The cells were shammed or irradiated with different dosages of UVB radiation and treated with the above TCM monomers. The damage of fibroblasts was observed with inverted phase contrast microscope.Cellular proliferation activity was detected by MTT method.The secretory volume of IL-6 and TNF-α was measured by ELISE. Results The damage degree of the cells irradiated was dependent with the irradiated doses and the proliferation activity reduced by 28%-44%.

After 3-8 passages, the oral CAFs and the normal mucosa fibroblasts from tissue culture were observed under light microscope. Vimentin,α-SMA and Cytokeratin protein were detected by immunohistochemistry SP method on glass coverslips. VEGF, TGF-β1, MMP-9, Tenascin-C mRNA were analyzed by semi-quantitative RT-PCR.

用组织块培养法获得原代CAFs和正常粘膜成纤维细胞，0.25%胰蛋白酶消化传代和纯化细胞；通过形态学观察和免疫细胞化学染色对口腔CAFs和NMFs进行鉴定：采用半定量RT-PCR检测口腔CAFs和NMFs 4种基因的表达。

In a word, mad1 gene or mad1 combining with c-myc gene could inhibit TCCB cell proliferation but not normal fibrocytes in vitro and in vivo, which targeted hTERT, suppressed its transcription and expression, and down-regulated the expression of cyclin D1 and TGF-β1, to further block the cell cycle, change cell morphology and suppress proliferation.

综上所述，mad1基因或mad1联合c-myc基因能在体内外抑制TCCB细胞的增殖，但对正常成纤维细胞无明显影响，二者以hTERT为作用靶点，抑制其转录和表达，并下调cyclin D1和TGF-β1的表达，进而阻止细胞周期、改变细胞形态和抑制癌细胞的增殖。

For the purpose of constructing mammary gland specific expressional vector, we use the updream regulation sequence of bovine BLG to regulate lacS gene to express in mammary gland. Positive clone cells are selected and purified by the expression Neo gene and report gene EGFP. So the cells can be used as sources to create transgenic animals by nuclear transfer techniques.
