摘要/Abstract

摘要： 目的：观察Ⅰ型骨形态发生蛋白（BMP）受体活化素Ⅰ型受体（ACVR1）对出生后小鼠下颌骨髁突软骨（MCC）细胞形态、增殖和分化的影响，为研究MCC相关性疾病的病因及治疗提供参考。方法：采用Cre-LoxP系统构建在C57BL/6J小鼠MCC细胞中条件性敲除ACVR1基因的动物模型。将基因型为Acvr1^fx/fx；RS/RS和Acvr1^+/-；Osterix （+）/（-）的雌性和雄性小鼠配对合笼，以子代Osterix-Cre （+）；Acvr1^fx/-；RS/+基因型小鼠为实验组，Osterix-Cre （+）；Acvr1^fx/+；RS/+小鼠为对照组。分别取新出生（n=3）、出生后21天（PN21）（n=4）和出生后42天（PN42）（n=5）雄性小鼠，X-gal染色检测MCC组织中Osterix-Cre表达，micro-CT法检测2组小鼠下颌骨髁突宽度和髁头长度，HE染色和甲苯胺蓝染色分析2组小鼠MCC细胞形态及各层软骨厚度，免疫组织化学（IHC）染色检测2组小鼠MCC组织中增殖细胞核抗原（PCNA）阳性细胞数和Ⅹ型胶原水平。结果：X-gal染色和IHC染色，ACVR1条件性基因缺失小鼠模型构建成功。在PN21时，与对照组比较，实验组小鼠下颌骨髁突宽度和髁头长度明显变短（P<0.05）；2组小鼠MCC细胞形态表现和结构无明显差异。与对照组比较，实验组小鼠肥大软骨细胞层（Hy）和成软骨细胞层（Ch）这2层及Hy单层MCC组织中PCNA阳性细胞数明显增多（P<0.05或P<0.01）。在PN42时，与对照组比较，实验组小鼠部分下颌骨髁突软骨细胞形态异常，部分髁突肥大软骨细胞的排列紊乱，实验组小鼠髁突软骨前1/3区的Hy和中1/3区除Hy以外的其他层细胞厚度明显增大（P<0.05或P<0.01）；与对照组比较，实验组小鼠MCC组织各层PCNA阳性细胞数和Ch中Ⅹ型胶原水平明显升高。结论：ACVR1通过抑制MCC细胞增殖和成软骨细胞向肥大软骨细胞的分化，从而影响MCC细胞形态及MCC组织结构。

Abstract: Objective: To observe the effect of type Ⅰbone morphogenetic protein(BMP)receptor activin A receptor type Ⅰ(ACVR1)on the morphology,proliferation and differentiation of the mandibular condylar cartilage (MCC) cells in the postnatal mice, and to provide the reference for the study on etiology and treatment of MCC-related disease. Methods: The C57BL/6J mouse model of conditional deletion of ACVR1 gene was constructed by using the Cre-LoxP system. The female and male mice with Acvr1^fx/fx; RS/RS and Acvr1^+/-; Osterix (+)/(-) genotypes were paired off with each other; the offspring Osterix-Cre (+); Acvr1^fx/-; RS/+ genotype mice were selected as experiment group,and the Osterix-Cre (+); Acvr1^fx/+; RS/+ mice were selected as control group. The newborn (n=3), postnatal day 21(PN21) (n=4) and PN42(n=5) male mice were selected. X-gal staining was used to detect the expressions of Osterix-Cre in MCC tissue of the mice in two groups,micro-CT was used to detect the condylar widths and condylar head lengths of mandible of the mice in two groups,HE and Toluidine blue staining were used to analyze the morphology of MCC cells and the thickness of caritilage in each layer of MCC tissue of the mice in two groups,immunohistochemical (IHC) staining was used to detect the number of proliferating cell nuclear antigen(PCNA)-positive cells and the level of type Ⅹ collagen in MCC tissue of the mice in two groups. Results: The X-gal staining and IHC results showed that the mouse model of ACVR1 gene conditional deletion was successfully constructed. At PN21, compared with control group, the condylar width and the condylar head length of mandible of the mice in experiment group were significantly shortened (P<0.05); the morphology of the MCC cells of the mice in two groups had no significant difference. Compared with control group, the number of PCNA-positive cells in the MCC cells of hypertrophic chondrocyte zone(Hy) and chondroblastic zone(Ch) and single Hy of the mice in experiment group were significantly increased(P<0.05 or P<0.01).At PN42, compared with control group, the shape of parts of the mandibular condylar cartilage cells of the mice in experiment group was abnormal, and the arrangement of some condylar chondrocytes was disordered, the cell thickness of the Ar, Pr and Ch in intermediate part and Hy in anterior part of the condylar cartilage of the mice in experiment group were significantly increased(P<0.05 or P<0.01); compared with control group, the number of PCNA-positive cells in each zone and the level of type Ⅹ collagen in Ch of MCC tissue of the mice in experiment group were incresed. Conclusion: ACVR1 affects the morphology of MCC cells and structure of MCC tissue by inhibiting the proliferation of MCC cells and the differentiation of chondroblasts into hypertrophic chondrocytes.
