Keiko Kudoh, Naoyuki Fukuda, Kazuya Akita, Natsumi Takamaru, Naito Kurio, 石川邦夫 and Youji Miyamoto : Reconstruction of rabbit mandibular bone defects using carbonate apatite honeycomb blocks with an interconnected porous structure., Journal of Materials Science. Materials in Medicine, Vol.34, No.1, 2022. (Summary) Carbonate apatite (COAp) granules are useful as a bone substitute because they can be remodeled to new natural bone in a manner that conforms to the bone remodeling process. However, reconstructing large bone defects using COAp granules is difficult because of their granular shape. Therefore, we fabricated COAp honeycomb blocks (HCBs) with continuous unidirectional pores. We aimed to elucidate the tissue response and availability of COAp HCBs in the reconstruction of rabbit mandibular bone defects after marginal mandibulectomy. The percentages of the remaining COAp area and calcified bone area (newly formed bone) were estimated from the histological images. COAp area was 49.1 ± 4.9%, 30.3 ± 3.5%, and 25.5 ± 8.8%, whereas newly formed bone area was 3.0 ± 0.6%, 24.3 ± 3.3%, and 34.7 ± 4.8% at 4, 8, and 12 weeks, respectively, after implantation. Thus, COAp HCBs were gradually resorbed and replaced by new bone. The newly formed bone penetrated most of the pores in the COAp HCBs at 12 weeks after implantation. By contrast, the granulation tissue scarcely invaded the COAp HCBs. Some osteoclasts invaded the wall of COAp HCBs, making resorption pits. Furthermore, many osteoblasts were found on the newly formed bone, indicating ongoing bone remodeling. Blood vessels were also formed inside most of the pores in the COAp HCBs. These findings suggest that COAp HCBs have good osteoconductivity and can be used for the reconstruction of large mandibular bone defects. The COAp HCB were gradually resorbed and replaced by newly formed bone.

(Summary) Programmed cell death-1 (PD-1) and its ligand programmed cell death 1 ligand 1 (PD-L1) are immune checkpoint inhibitors that play an important role in the host immune avoidance mechanism of tumors. The relationship between PD-L1 expression and malignancy has been reported in various types of cancer, such as lung and gastric cancer. In addition, epithelial-mesenchymal transition (EMT) of cancer cells is deeply involved in the invasion and metastasis of cancer. It has been reported that zinc finger E-box binding homeobox 1 (ZEB-1), an EMT inducer, contributes to metastasis in pancreatic and colon cancer. The present study aimed to investigate the relationship between the expression patterns of two markers, PD-L1 and ZEB-1, and clinicopathological characteristics and prognosis of oral squamous cell carcinoma (OSCC). Biopsy or surgical excision specimens from 169 patients with OSCC were used in the present study. Immunohistochemical staining with monoclonal anti-PD-L1 antibody and anti-ZEB-1 antibody was conducted. Cases with >1% tumor cells positive for PD-L1 and those with >10% tumor cells positive for ZEB-1 were considered positive, respectively. The findings revealed that individual expression of PD-L1 and ZEB-1 in OSCC was not associated with tumor size, degree of differentiation or Yamamoto-Kohama invasion pattern classification. However, co-expression of PD-L1 and ZEB-1 was associated with higher cervical lymph node metastasis and a lower survival rate. In conclusion, the results of the present study indicated that co-expression of PD-L1 and ZEB-1 could serve as a potential marker for the prognosis of patients with OSCC.

Part A, Vol.108, No.3, 709-721, 2020. (Summary) Carbonate apatite (CO Ap) granules are known to show good osteoconductivity and replaced to new bone. On the other hand, it is well known that a porous structure allows bone tissue to penetrate its pores, and the optimal pore size for bone ingrowth is dependent on the composition and structure of the scaffold material. Therefore, the aim of this study was to fabricate various porous CO Ap granules through a two-step dissolution-precipitation reaction using CaSO as a precursor and 30-, 50-, 120-, and 205-μm diameter microfibers as porogen and to find the optimal pore size of CO Ap. Porous CO Ap granules were successfully fabricated with pore size 8.2-18.7% smaller than the size of the original fiber porogen. Two weeks after the reconstruction of rabbit calvarial bone defects using porous CO Ap granules, the largest amount of mature bone was seen to be formed inside the pores of CO Ap (120) [porous CO Ap granules made using 120-μm microfiber] followed by CO Ap (50) and CO Ap (30). At 4 and 8 weeks, no statistically significant difference was observed based on the pore size, even though largest amount of mature bone was formed in case of CO Ap (120). It is concluded, therefore, that the optimal pore size of the CO Ap is that of CO Ap (120), which is 85 μm.

(Summary) A main inorganic component of human bone is not hydroxyapatite but carbonate apatite (CQ3Ap). Hydroxyapatite is not resorbed in the body but C03Ap can be resorbed and replaced with bone. We have succeeded in fabricating low crystalline CQ3Ap without sintering by dissolution-precipitation reaction using calcium hydroxide as a precursor. C03Ap showed excellent biocompatibility and faster bone formation compared to other bone substitutes (anorganic bovine bone and hydroxyapatite) in rabbit femur and dog mandible. Clinical study on effectiveness and safety of C03Ap granules in sinus floor augmentation was successfully concluded in 2016. CQ3Ap granules were approved by Japanese government in 2017, and marketed in 2018 as Cytrans® Granules. This comprehensive review explains the clinical cases of sinus lift and alveolar ridge augmentation of Cytrans® and its recommended clinical usage. Furthermore, we have succeeded in developing porous C03Ap and showed it was useful for reconstruction of mandibular bone defect in rabbit model and also aim to use it as a scaffold for bone regenerative medicine.
