We identified the Vwde as a novel ECM protein through bioinformatics using the NCBI expressed sequence tag database for mice. Vwde complementary DNA encodes 1773 amino acids containing a signal peptide, a von Willebrand factor type D domain, and tandem calcium-binding EGF-like domains. Real-time polymerase chain reaction demonstrated that Vwde is highly expressed in tooth tissue but not in other tissues including the brain, lung, heart, liver, kidney, and bone. In situ hybridization revealed that the IEEs expressed Vwde messenger RNA in developing teeth. Immunostaining showed that VWDE was localized at the proximal and the distal ends of the pericellular regions of the IEEs. Vwde was induced during the differentiation of mouse dental epithelium-derived M3H1 cells. Vwde-transfected M3H1 cells secreted VWDE protein into the culture medium and inhibited cell proliferation, whereas ameloblastic differentiation was promoted. Furthermore, Vwde increased the phosphorylation of extracellular signal-regulated kinase 1/2 and protein kinase B and strongly induced the expression of the intercellular junction protein, N-cadherin (Ncad). Interestingly, the suppression of endogenous Vwde inhibited the expression of Ncad. Finally, we created Vwde-knockout mice using the CRISPR-Cas9 system. Vwde-null mice showed low mineral density, rough surface, and cracks in the enamel, indicating the enamel hypoplasia phenotype. Our findings suggest that Vwde assembling the matrix underneath the IEEs is essential for Ncad expression and enamel formation.","ja":"Cell- and tissue-specific extracellular matrix (ECM) composition plays an important role in organ development, including teeth, by regulating cell behaviors, such as cell proliferation and differentiation.

Immunostaining showed that VWDE was localized at the proximal and the distal ends of the pericellular regions of the IEEs. Vwde was induced during the differentiation of mouse dental epithelium-derived M3H1 cells. Vwde-transfected M3H1 cells secreted VWDE protein into the culture medium and inhibited cell proliferation, whereas ameloblastic differentiation was promoted. Furthermore, Vwde increased the phosphorylation of extracellular signal-regulated kinase 1/2 and protein kinase B and strongly induced the expression of the intercellular junction protein, N-cadherin (Ncad). Interestingly, the suppression of endogenous Vwde inhibited the expression of Ncad. Finally, we created Vwde-knockout mice using the CRISPR-Cas9 system. Vwde-null mice showed low mineral density, rough surface, and cracks in the enamel, indicating the enamel hypoplasia phenotype. Our findings suggest that Vwde assembling the matrix underneath the IEEs is essential for Ncad expression and enamel formation."},"publication_date":"2021-12-26","publication_name":{"en":"Journal of Cellular Physiology","ja":"Journal of Cellular Physiology"},"volume":"Vol.237","number":"No.3","starting_page":"1964","ending_page":"1979","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1002/jcp.30667"],"issn":["1097-4652"]},"published_paper_type":"scientific_journal"},"priority":"input_data"} line:8, {"insert":{"user_id":"6000017140","type":"published_papers","id":"33902704"},"force":{"see_also":[{"@id":"https://repo.lib.tokushima-u.ac.jp/ja/116383","label":"url"},{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=382624","label":"url"}],"paper_title":{"en":"Peripherally Administered Botulinum Toxin Type A Localizes Bilaterally in Trigeminal Ganglia of Animal Model","ja":"Peripherally Administered Botulinum Toxin Type A Localizes Bilaterally in Trigeminal Ganglia of Animal Model"},"authors":{"en":[{"name":"Waskitho Arief"},{"name":"Yamamoto Yumiko"},{"name":"Raman S"},{"name":"Kano Fumiya"},{"name":"Yan Huijiao"},{"name":"Raju R"},{"name":"Afroz S"},{"name":"Morita Tsuyoshi"},{"name":"Ikutame Daisuke"},{"name":"Okura Kazuo"},{"name":"Ohshima Masamitsu"},{"name":"Yamamoto Akihito"},{"name":"Baba Otto"},{"name":"Matsuka Yoshizo"}],"ja":[{"name":"ARIEF WASKITHO"},{"name":"Yamamoto Yumiko"},{"name":"RAMAN SWARNA LAKSHMI"},{"name":"加納 史也"},{"name":"YAN HUIJIAO"},{"name":"RESMI RAJU"},{"name":"SHAISTA AFROZ"},{"name":"守田 剛"},{"name":"生田目 大介"},{"name":"大倉 一夫"},{"name":"大島 正充"},{"name":"山本 朗仁"},{"name":"馬場 麻人"},{"name":"松香 芳三"}]},"publication_date":"2021-10-05","publication_name":{"en":"Toxins","ja":"Toxins"},"volume":"Vol.13","number":"No.10","starting_page":"704","ending_page":"704","languages":["eng"],"referee":true,"identifiers":{"doi":["10.3390/toxins13100704"],"issn":["2072-6651"]},"published_paper_type":"scientific_journal"},"priority":"input_data"} line:9, {"insert":{"user_id":"6000017140","type":"published_papers","id":"36920370"},"force":{"see_also":[{"@id":"https://repo.lib.tokushima-u.ac.jp/ja/117268","label":"url"},{"@id":"https://www.ncbi.nlm.nih.gov/pubmed/34548598","label":"url"},{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=385382","label":"url"}],"paper_title":{"en":"Conditioned medium from stem cells derived from human exfoliated deciduous teeth ameliorates NASH via the GutLiver axis","ja":"Conditioned medium from stem cells derived from human exfoliated deciduous teeth ameliorates NASH via the GutLiver axis"},"authors":{"en":[{"name":"Muto Hisanori"},{"name":"Ito Takanori"},{"name":"Tanaka Taku"},{"name":"Yokoyama Shinya"},{"name":"Yamamoto Kenta"},{"name":"Imai Norihiro"},{"name":"Ishizu Yoji"},{"name":"Maeda Keiko"},{"name":"Honda Takashi"},{"name":"Ishikawa Tetsuya"},{"name":"Kato Asuka"},{"name":"Ohshiro Taichi"},{"name":"Kano Fumiya"},{"name":"Yamamoto Akihito"},{"name":"Sakai Kiyoshi"},{"name":"Hibi Hideharu"},{"name":"Ishigami Masatoshi"},{"name":"Fujishiro Mitsuhiro"}],"ja":[{"name":"Muto Hisanori"},{"name":"Ito Takanori"},{"name":"Tanaka Taku"},{"name":"Yokoyama Shinya"},{"name":"Yamamoto Kenta"},{"name":"Imai Norihiro"},{"name":"Ishizu Yoji"},{"name":"Maeda Keiko"},{"name":"Honda Takashi"},{"name":"Ishikawa Tetsuya"},{"name":"Kato Asuka"},{"name":"Ohshiro Taichi"},{"name":"加納 史也"},{"name":"山本 朗仁"},{"name":"Sakai Kiyoshi"},{"name":"Hibi Hideharu"},{"name":"Ishigami Masatoshi"},{"name":"Fujishiro Mitsuhiro"}]},"description":{"en":"Non-alcoholic steatohepatitis (NASH) occurrence has been increasing and is becoming a major cause of liver cirrhosis and liver cancer.

Numerous studies have reported that administrations of various types of MSCs improve arthritis symptoms in animal models, by paracrine mechanisms. However, the therapeutic effects of the secreted factors alone, without the cell graft, have been uncertain. Here, we show that a single intravenous administration of serum-free conditioned medium (CM) from human deciduous dental pulp stem cells (SHED-CM) into anti-collagen type II antibody-induced arthritis (CAIA), a mouse model of rheumatoid arthritis (RA), markedly improved the arthritis symptoms and joint destruction. The therapeutic efficacy of SHED-CM was associated with an induction of anti-inflammatory M2 macrophages in the CAIA joints and the abrogation of RANKL expression. SHED-CM specifically depleted of an M2 macrophage inducer, the secreted ectodomain of sialic acid-binding Ig-like lectin-9 (ED-Siglec-9), exhibited a reduced ability to induce M2-related gene expression and attenuate CAIA.

Numerous studies have reported that administrations of various types of MSCs improve arthritis symptoms in animal models, by paracrine mechanisms. However, the therapeutic effects of the secreted factors alone, without the cell graft, have been uncertain. Here, we show that a single intravenous administration of serum-free conditioned medium (CM) from human deciduous dental pulp stem cells (SHED-CM) into anti-collagen type II antibody-induced arthritis (CAIA), a mouse model of rheumatoid arthritis (RA), markedly improved the arthritis symptoms and joint destruction. The therapeutic efficacy of SHED-CM was associated with an induction of anti-inflammatory M2 macrophages in the CAIA joints and the abrogation of RANKL expression. SHED-CM specifically depleted of an M2 macrophage inducer, the secreted ectodomain of sialic acid-binding Ig-like lectin-9 (ED-Siglec-9), exhibited a reduced ability to induce M2-related gene expression and attenuate CAIA. SHED-CM also inhibited the RANKL-induced osteoclastogenesis in vitro. Collectively, our findings suggest that SHED-CM provides multifaceted therapeutic effects for treating CAIA, including the ED-Siglec-9-dependent induction of M2 macrophage polarization and inhibition of osteoclastogenesis.

Shisa2 encodes an endoplasmic reticulum (ER) protein that cell-autonomously inhibits FGF and Wnt signaling by preventing the maturation and the cell-surface expression of their receptors. Shisa2 is expressed in the PSM and its knockdown caused a reduction in somite number by the delayed maturation of PSM and anterior shift of the transition; however, the phase of the segmental clock remained intact.

Shisa2 is expressed in the PSM and its knockdown caused a reduction in somite number by the delayed maturation of PSM and anterior shift of the transition; however, the phase of the segmental clock remained intact. These phenotypes were abolished by the inhibition of both FGF and Wnt signals, but by neither alone. We therefore propose that the individual inhibition of both types of signaling by the regulation of receptor maturation in the ER plays an essential role in the establishment of proper segmental patterning."},"publication_date":"2006-10-25","publication_name":{"en":"Development","ja":"Development"},"volume":"Vol.133","number":"No.23","starting_page":"4643","ending_page":"4654","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1242/dev.02657"],"issn":["0950-1991"]},"published_paper_type":"scientific_journal"},"priority":"input_data"} line:45, {"insert":{"user_id":"6000017140","type":"published_papers"},"similar_merge":{"see_also":[{"@id":"https://www.ncbi.nlm.nih.gov/pubmed/15680328","label":"url"},{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=321536","label":"url"}],"paper_title":{"en":"Shisa promotes head formation through the inhibition of receptor protein maturation for the caudalizing factors, Wnt and FGF.","ja":"Shisa promotes head formation through the inhibition of receptor protein maturation for the caudalizing factors, Wnt and FGF."},"authors":{"en":[{"name":"Yamamoto Akihito"},{"name":"Nagano Takashi"},{"name":"Takehara Shoko"},{"name":"Hibi Masahiko"},{"name":"Aizawa Shinichi"}],"ja":[{"name":"山本 朗仁"},{"name":"Nagano Takashi"},{"name":"Takehara Shoko"},{"name":"日比 正彦"},{"name":"Aizawa Shinichi"}]},"description":{"en":"Head formation requires simultaneous inhibition of multiple caudalizing signals during early vertebrate embryogenesis.

Recent studies provided evidence that the Notch-Delta and the FGFR (fibroblast growth factor receptor) signalling pathways are required for segmentation. In addition, the Mesp family of bHLH transcription factors have been implicated in establishing a segmental prepattern in the presomitic mesoderm. In this study, we have characterized zebrafish mesp-a and mesp-b genes that are closely related to Mesp family genes in other vertebrates. During gastrulation, only mesp-a is expressed in the paraxial mesoderm at the blastoderm margin. During the segmentation period, both genes are segmentally expressed in one to three stripes in the anterior parts of somite primordia. In fused somites (fss) embryos, in which all early somite boundary formation is blocked, initial mesp-a expression at the gastrula stage remains intact, but the expression of mesp-a and mesp-b is not detected during the segmentation period. This suggests that these genes are downstream targets of fss at the segmentation stage. Comparison with her1 expression (Müller, M., von Weizsäcker, E. and Campos-Ortega, J. A. (1996) Development 122, 2071-2078) suggests that, like her1, mesp genes are not expressed in primordia of the first several somites. Furthermore, we found that zebrafish her1 expression oscillates in the presomitic mesoderm. The her1 stripe, which first appears in the tailbud region, moves in a caudal to rostral direction, and it finally overlaps the most rostral mesp stripe. Thus, in the trunk region, both her1 and mesp transcripts are detected in every somite primordium posterior to the forming somites. Ectopic expression of Mesp-b in embryos causes a loss of the posterior identity within the somite primordium, leading to a segmentation defect. These embryos show a reduction in expression of the posterior genes, myoD and notch5, with uniform expression of the anterior genes, FGFR1, papc and notch6. These observations suggest that zebrafish mesp genes are involved in anteroposterior specification within the presumptive somites, by regulating the essential signalling pathways mediated by Notch-Delta and FGFR.","ja":"Segmentation of a vertebrate embryo begins with the subdivision of the paraxial mesoderm into somites through a not-well-understood process.

The etiology and management of TMJ-OA are explained briefly, animal models of TMJ-OA are described, and the effectiveness of LIPUS on cell metabolism and tissue regeneration in the TMJ is discussed."},"publication_date":"2020-06-08","publication_name":{"en":"Annals of Biomedical Engineering","ja":"Annals of Biomedical Engineering"},"volume":"Vol.48","number":"No.8","starting_page":"2158","ending_page":"2170","languages":["eng"],"identifiers":{"doi":["10.1007/s10439-020-02540-x"],"issn":["1573-9686"]},"misc_type":"introduction_scientific_journal"},"priority":"input_data"} line:2, {"insert":{"user_id":"6000017140","type":"misc"},"similar_merge":{"see_also":[{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=369735","label":"url"}],"paper_title":{"en":"Multifaceted neuro-regenerative activities of human dental pulp stem cells for functional recovery after spinal cord injury.","ja":"Multifaceted neuro-regenerative activities of human dental pulp stem cells for functional recovery after spinal cord injury."},"authors":{"en":[{"name":"Yamamoto Akihito"},{"name":"Kiyoshi S"},{"name":"Kohki M"},{"name":"Kano Fumiya"},{"name":"Minoru U"}],"ja":[{"name":"山本 朗仁"},{"name":"Kiyoshi S"},{"name":"Kohki M"},{"name":"加納 史也"},{"name":"Minoru U"}]},"publication_date":"2014","publication_name":{"en":"Neuroscience Research","ja":"Neuroscience Research"},"volume":"Vol.78","starting_page":"16","ending_page":"20","languages":["eng"],"identifiers":{"issn":["0168-0102"]},"misc_type":"introduction_scientific_journal"},"priority":"input_data"} line:3, {"insert":{"user_id":"6000017140","type":"misc"},"similar_merge":{"see_also":[{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=321545","label":"url"}],"paper_title":{"en":"Molecular basis for specification of the vertebrate head field","ja":"Molecular basis for specification of the vertebrate head field"},"authors":{"en":[{"name":"Yamamoto Akihito"}],"ja":[{"name":"山本 朗仁"}]},"publication_date":"2009","publication_name":{"en":"Interface Oral Health Science","ja":"Interface Oral Health Science"},"starting_page":"27","ending_page":"32","languages":["eng"],"misc_type":"introduction_scientific_journal"},"priority":"input_data"} line:4, {"insert":{"user_id":"6000017140","type":"misc","id":"20263092"},"force":{"see_also":[{"@id":"https://www.scopus.com/record/display.url?eid=2-s2.0-85009580354&origin=inward","label":"url"},{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=321546","label":"url"}],"paper_title":{"en":"Regulation of Wnt and FGF Signaling within the Endoplasmic Reticulum for Head Formation","ja":"Regulation of Wnt and FGF Signaling within the Endoplasmic Reticulum for Head Formation"},"authors":{"en":[{"name":"Yamamoto Akihito"}],"ja":[{"name":"山本 朗仁"}]},"publication_date":"2006","publication_name":{"en":"Journal of Oral Biosciences","ja":"Journal of Oral Biosciences"},"volume":"Vol.48","number":"No.1","starting_page":"18","ending_page":"21","languages":["eng"],"identifiers":{"doi":["10.2330/joralbiosci.48.18"],"issn":["1349-0079"]},"misc_type":"introduction_scientific_journal"},"priority":"input_data"} line:5, {"insert":{"user_id":"6000017140","type":"misc","id":"20263113"},"force":{"see_also":[{"@id":"https://www.ncbi.nlm.nih.gov/pubmed/26612624","label":"url"},{"@id":"https://web.db.tokushima-u.ac.jp/cgi-bin/edb_browse?EID=321533","label":"url"}],"paper_title":{"en":"Conditioned media from hypoxic-cultured human dental pulp cells promotes bone healing during distraction osteogenesis.","ja":"Conditioned media from hypoxic-cultured human dental pulp cells promotes bone healing during distraction osteogenesis."},"authors":{"en":[{"name":"Fujio Masahito"},{"name":"Xing Zhe"},{"name":"Sharabi Niyaz"},{"name":"Xue Ying"},{"name":"Yamamoto Akihito"},{"name":"Hibi Hideharu"},{"name":"Ueda Minoru"},{"name":"Fristad Inge"},{"name":"Mustafa Kamal"}],"ja":[{"name":"Fujio Masahito"},{"name":"Xing Zhe"},{"name":"Sharabi Niyaz"},{"name":"Xue Ying"},{"name":"山本 朗仁"},{"name":"Hibi Hideharu"},{"name":"Ueda Minoru"},{"name":"Fristad Inge"},{"name":"Mustafa Kamal"}]},"description":{"en":"Distraction osteogenesis (DO) is a surgical procedure used to correct various skeletal disorders. Improving the technique by reducing the healing time would be of clinical relevance. The aim of this study was to determine the angiogenic and regenerative potential of conditioned media (CMs) collected from human dental pulp cells (hDPCs) grown under different culture conditions. CM collected from cells under hypoxia was used to improve bone healing and the DO procedure in vivo. The angiogenic potentials of CMs collected from hDPCs grown under normoxic (-Nor) and hypoxic (-Hyp) conditions were evaluated by quantitative PCR (VEGF-A, angiopoietin-1, angiopoietin-2, interleukin-6 (IL-6) and CXCL12), ELISA assays (VEGF-A, Ang-2), tube-formation and wound-healing assays, using human umbilical vein endothelial cells. The results demonstrated that hypoxic CM had significantly higher angiogenic potential than normoxic CM. Human fetal osteoblasts (hFOBs) were exposed to CM, followed by alizarin red staining, to assess the osteogenic potential. It was found that CM did not enhance the mineralization capacity of hFOBs. DO was performed in the tibiae of 30 mice, followed by a local injection of 20µl CM (CM-Nor and CM-Hyp groups) or serum-free DMEM (control group) into the distraction zone every second day. The mice were sacrificed at days 13 and 27. The CM-Hyp treatment revealed a higher X-ray density than the control group (p<0.05). Our study suggests that the angiogenic effect promoted by hypoxic culture conditions is dependent on VEGF-A and Ang-2 released from hDPCs. Furthermore, CM-Hyp treatment may thus improve the DO procedure, accelerating bone healing. © 2015 The Authors.
