Bone marrow-derived mesenchymal stem cells are capable of chondrogenesis, making them a possible source of cells for injectable cartilage tissue engineering. There exist different ideas on the ability of mesenchymal stem cells's chondrogenesis in monolayer culture. Because of this, the effect of adult rabbit's bone marrow-derived mesenchymal stem cells chondrogenesis in monolayer culture was studied. The mesenchymal stem cells was isolated from adult rabbit's bone marrow and monolayer cultured. TGF-β1, Vit-C and Dexamethasone were used. Immunohistochemistry analyses and histological staining of H-E, Methylaniline blue and Alcian blue were performed to identify the expression of collagen type Ⅱ and cartilage associated matrix. The results showed that the induced cells expressed and produced collagen type Ⅱ and cartilage associated matrix. This suggests that the differentiation of adult rabbit's marrow-derived mesenchymal stem cells into chondrocyte in monolayer culture is feasible and may be induced by TGF-β1, Vit-C and Dexamethasone.

骨髓基质干细胞的软骨分化潜能使其可能成为可注射组织工程化软骨研究的种子细胞，为探讨体外培养的骨髓基质干细胞在平面诱导条件下软骨分化的可行性，我们进行下列实验：获取并体外平面培养成体兔骨髓基质干细胞，应用TGF-β〓、Vit-C和地塞米松对其软骨分化诱导，诱导后的骨髓基质干细胞行细胞爬片组织学和Ⅱ型胶原免疫组化，结果证实，诱导后骨髓基质干细胞可分泌Ⅱ型胶原，组织学染色可见类似于软骨细胞，由此证明体外培养的骨髓基质干细胞在平面诱导条件下可以软骨分化，其软骨诱导因子为TGF-β〓、Vit-C和地塞米松。

Control group: inflammatory cell infiltration (1W); inflammatory cell disappearance, fibroblast and capillary tachyauxesis (2W); osteoblast appearance around bone defect (1M); small amount neoformative bone tissue around bone defect.

对照组：术后1周，骨缺损区周围有大量炎性细胞浸润；术后2周，炎性渗出吸收，成纤维细胞、毛细血管生长活跃；术后1个月，骨缺损区周围有成骨细胞；术后3个月，骨缺损边缘有少量新骨沉积。

Autogenous bone is an ideal material to repair bone defect, however, autogenous bone harvest increases patient trauma and pain. Moreover, its source is very limited, and it could not meet the requirement to repair large-segment transplantation. Metal prosthesis has problems such as sensitivity to defect, loosening, breakage, bad histocompatibility and nondegradation.

自体骨虽然是理想的骨缺损修复材料，但自体取骨增加了患者的创伤和痛苦，并且供骨的来源有限，难以满足大段骨移植的要求；金属假体对缺口敏感，存在松动、断裂、组织相容性差、不可降解等问题。

The common people does everything possible to need to be grasping its evidence that can be got hold of in lawsuits or arguments , can claim indemnity one, evidence that can be got hold of in lawsuits or arguments does not also need to set aside bone , the bone should not also be very many set aside ice; Reporter who has chosen bone with a covetous look that is to big news having speculation value absolutely , the problem does not also need to create problem, in that USA does not become a problem's filter oil powder having arrived at China is a problem, being put into use filtering oil powder is pinker than being needless to filter oil also being problem , nonutility therefore in the homeland the eatery is fundamental, that the common people knows this neither is what thing.

老百姓想方设法要抓着它的把柄，可以索赔它一笔，没有把柄也要挑出骨头，没有骨头也要挑出冰太多；记者虎视眈眈谁挑着了骨头那绝对是有炒作价值的大新闻，没有问题也要创造问题，在美国不成为问题的滤油粉到了中国那就是个问题，使用滤油粉比不用滤油粉更是个问题，所以国内餐馆基本不用，老百姓也不了解这是个什么东西。

Methods BMSCs isolated from rabbit iliac bone marrow were culture-expanded in vitro. The injectable tissue-engineered bone constructed from autologous PRP, FG, and BMSCs was cultured in vitro, and its biological characteristics were observed including the time of gel formation, histological features, seed cell survival and microscopic structures. Results The constructed injectable tissue-engineered bone began gel formation within 20 to 30 s, and after a week-long culture, the gelatine began to degrade, and numerous well viable fusiform cells could be seen to adhere to the bottom of the Petil dish, Scanning electron microscopy identified globular and olivary cells embedded in the fibrin glue, and numerous small particles could be seen around of the cells.
