Objective To investigate the proliferative and osteogenic activity of periosteal osteoblasts, calvarial osteoblasts and bone marrow stromal cells from the same embryo.

目的 比较从同一胚胎来源的骨膜成骨细胞、颅骨成骨细胞和骨髓基质干细胞的分裂增殖能力和细胞的功能状态。

Methods: The human osteoblasts were isolated from the trabecular bone by ...

结果：所分离培养的细胞具有成骨细胞的形态特征，保持了其在体内的功能；MG63细胞株和人成骨细胞均表达PRA和PRBmRNA和蛋白质。

Drived from the rabbit stromal cells of bone marrow from the trochanteric regoin of femur of rabbit and cultured the cells with special cultulal fluid in vitro.

结果：采用本法在体外培养的兔成骨细胞生长良好，生化指标稳定，表现出与典型的成骨细胞相似的形态特征和生物学特性。

Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin, demineralized bone matrix were implanted into the muscle pouch of mice, at different times after implantation, the immunological, histological and alkaline phosphatase assay were conducted. The results revealed that all four kinds of allogeneic implants activated specific cellular and humoral immune responses, most notably in fresh bone group, the AAA, BMG and DBM inhibited the proliferation of the lymphocytes in vitro and BMG had the most powerful inhibiting action, allogeneic AAA, BMG and DBM might induce heterotopic osteogenesis in vivo, however, there were obvious difference in ALP and histomorphometry between allografts and isografts.

在小鼠肌肉内植入同种异体或同系新鲜骨、自消化抗原去除骨、骨基质明胶、脱钙骨基质，术后免疫学、碱性磷酸酶、组织学检查发现：4种同种异体植入物均可引发特异性细胞免疫反应和体液免疫反应，其中以新鲜骨移植引发的免疫反应最为显著；自消化抗原去除骨、骨基质明胶、脱钙骨基质在体外具有抑制淋巴细胞增殖的作用，骨基质明胶对淋巴细胞增殖的抑制作用最显著；同种异体与同系4种植入物在体内成骨活性有显著差异；自消化抗原去除骨、骨基质明胶、脱钙骨基质均有异位诱导成骨活性，其中骨基质明胶骨诱导活性最佳。

The proliferation of osteoblast was measured by thiazolyl blue,activity of alkaline-phosphotase was observed with Golden s method and alizarin red stain was used to measure the mineral nodes of osteoblasts.

结果 0 10 g·L-1的麦胚提取物可以促进体外培养大鼠成骨细胞的增殖和分化作用，0 5 0g·L-1促使成骨细胞矿化结节的形成。
