We have researched distribution of TGF β and its receptor in various age group and discs of various degeneration grade, found that positive ratio of TGF β and its receptor is higher in below 40 year old group and discs of MRI Ⅰ and Ⅱ grade, mainly occur in fibrous cartilagous cells of fibrous annulus and nucleus pulpous; In group of 40-60 years old and grade Ⅱ and Ⅲ discs, TGF β decreased and TGF β R decreased not as much as TGF β; In above 60 years old group, TGF β and its receptor almost disappear.

生长因子包括TGF-β对细胞功能有重要调节作用，它是一种相对分子质量为2.5×10〓的二聚体多肽，几乎参与了哺乳动物所有细胞的病理，生理过程，尤其是在细胞外基质的产生及调控方面意义重大，且TGF-β已被公认为是与胶原代谢关系最密切的细胞因子。胡有谷、陈宏等，应用杂交技术检测了TGF-β对椎间盘Ⅰ、Ⅲ型胶原MRA的调节作用。

①Rat MSC and VSMC were cultured and identified, respectively. MSC were labeled with DAPI firstly, and then co-cultivated with VSMC. The changes of morphology and ultrastructure of co-cultured cells were observed. Immunfluorescence analysis was performed by using monoclonal antibodies against specific antigen.②We established the regulatable system in two steps: a stable MSC line expressing rtTA has been constructed and characterized firstly by transfected with pUHD 17-1hyg and then selected by hygromycin B; in a second step, this line was used for trandfer the AT2R gene to MSC to get the well establishing double stable MSC lines;③The expression of AT2R regulated by doxycycline was evaluated by western blot;④The MSCs were transduced into rat carotid arteries with regulatable AT2R gene after the establishment of rat carotid balloon injury restenosis model. The intimal/medial area ratio were measured by digital analysis system.

研究方法：(1)密度梯度离心法及胶原酶消化法分别培养原代大鼠MSC及VSMC，细胞共培养并行免疫荧光化学染色和透射电镜观察超微结构；(2)组成受Dox调控的哺乳动物表达系统的四种成分的转化、扩增及提纯并酶切鉴定；(3)采用常规分子生物学方法连续两个回合转染体外培养的MSC，并分别采用发光计检测不同细胞克隆萤光素酶活性改变以及RT-PCR方法检测AT2R目的基因mRNA表达情况，根据各个细胞克隆受Dox调控表达的程度，选择低背景、高诱导表达AT2R的细胞系，作为双重稳定MSC细胞系；蛋白免疫印迹法观察该细胞系在Dox调控下AT2R表达的时相性、持续性及在不同浓度Dox调控下的表达情况；(4)建立大鼠颈动脉球囊损伤动物模型，将双重稳定MSC在术中导入血管，分别于14 d、28 d进行病理切片，检测可调控AT2R对新生内膜增生的影响；采用RT-PCR免疫组织化学免疫荧光等技术观察AT2R基因在新生内膜中的表达以及细胞外基质成分表达的改变，TUNEL法检测血管组织中细胞凋亡的变化情况。
