摘要 目的:观察不同浓度孕酮、左炔诺孕酮和醋酸甲羟孕酮对体外培养子宫肌瘤细胞生长的影响。方法:体外培养子宫肌瘤细胞,采用四甲基偶氮唑蓝(MTT)法检测应用不同浓度孕酮、左炔诺孕酮和醋酸甲羟孕酮后子宫肌瘤细胞增殖的情况,并采用细胞免疫化学方法检测增殖细胞核抗原(PCNA)的表达。结果:成功进行子宫肌瘤细胞的原代培养,加入浓度为10、1000ng/mL孕酮、左炔诺孕酮和醋酸甲羟孕酮后,与对照组相比,明显促进细胞增殖,差异有显著性(P<0.05),并且呈剂量依赖性,浓度为0.1ng/mL时轻度促进细胞增殖,与对照组相比差异无显著性(P>0.05)。加入浓度为1000ng/mL孕酮、左炔诺孕酮和醋酸甲羟孕酮后,与对照组相比,明显促进胞核内PCNA的表达(P<0.05)。结论:孕酮、左炔诺孕酮和醋酸甲羟孕酮可刺激体外培养肌瘤细胞增殖,呈剂量依赖性。
