摘要: 本试验应用不同消化分离途径获取犬子宫内膜基质细胞,调节培养液中雌激素(E2)和孕酮(P4)的浓度,采用MTT法测定E2和P4浓度水平对犬子宫内膜基质细胞体外增殖的影响,利用细胞免疫组织化学法鉴定细胞并测定细胞孕酮受体(PR)表达与激素浓度水平的相关性。结果表明,E2浓度变化(15、30、100 pg/mL)对犬子宫内膜基质细胞的增殖和PR的表达均没有显著的调节作用(P>0.05);P4(15、30 ng/mL)对犬子宫内膜基质细胞的增殖有显著促进作用(P<0.05),P4(3、15、30 ng/mL)对犬子宫内膜基质细胞PR的表达具有显著的抑制作用(P<0.05),其影响程度与浓度和作用时间关系密切。

Abstract: In this study different digestion and isolation methods were applied to obtain canine endometrial stromal cells (ESCs), different concentration levels were set for estrogen (E2) and progesterone (P4), then MTT method was used to measure their effect on cell proliferation in vitro, also cell immunohistochemistry was used for cell identification and measurement of effect on progesterone receptors (PR) expression.The results indicated that E2 (15, 30 and 100 pg/mL) showed no significant regulations on both cell proliferation and PR expression, P4 (15 and 30 ng/mL) had significant promoting effect on proliferation of ESCs (P<0.05), P4 (3, 15 and 30 ng/mL) showed significant inhibitory effect on PR expression (P<0.05), the regulation level was related to concentration and acting time.

Key words: progesterone receptor (PR); primary culture; cell proliferation; canine endometrium stromal cells
