4、作用.在皮肤鳞癌中,有关MMP9的研究报道很少,其结果也不完全一致.我们通过免疫组织化学技术检测Boouscellcarcinoma,SCC)组织中MMP9和CD34的表达,并对MMP9的表达与微血管密度(MVD)做定量分析,探讨皮肤鳞状细胞癌、BoAb(MAB0245)和CD34mAb((MAB0034),免疫组化SP试剂盒(KIT9710)及DAB试剂盒均购自福州迈新生物技术有限公司.1.2方法所有组织均经40g/L甲醛液固定,常规石蜡包埋切片,连续切片5张,厚约4μm.采用SP法,免疫组化染色程序按试剂盒说明书进行.阳性对照采用自身对照,.freelanD,StemY,Shpize
