To investigate the immunocytochemical expression and presence of mRNA transcripts of oncostatin M (OSM) and its exclusive receptor (OSM-Rbeta) in ovaries from human adults and fetuses.
Immunocytochemical and reverse transcription polymerase chain reaction (RT-PCR) study.
Major tertiary care and referral academic centers.
PATIENT(S): Ten women and girls undergoing laparoscopic ovarian biopsy and 30 women undergoing second-trimester and third-trimester pregnancy terminations.
INTERVENTION(S): None.
MAIN OUTCOME MEASURE(S): Microscopic morphometric analysis, immunocytochemistry for OSM and OSM-Rbeta, and RT-PCR analyses.
RESULT(S): There was strong to moderate immunocytochemical staining for OSM in both oocytes and granulosa cells of follicles from primordial stages onwards in ovaries from both fetuses and adults/adolescents. OSM-Rbeta was detected mainly in the oocytes. Transcripts of OSM and OSM-Rbeta RNA were detected by RT-PCR analyses.
CONCLUSION(S): The expression of OSM and its receptor in ovarian tissue from fetuses and women suggests a possible role of OSM in growth initiation of human primordial follicles.
研究抑瘤素M(OSM)及其特异性受体(OSM-Rβ)在成年和胎儿卵巢中的免疫细胞化学表达及mRNA转录本的存在情况。
免疫细胞化学和逆转录聚合酶链反应(RT-PCR)研究。
主要的三级医疗和转诊学术中心。
10名接受腹腔镜卵巢活检的女性和女孩,以及30名接受孕中期和孕晚期终止妊娠的女性。
无。
显微镜形态计量分析、OSM和OSM-Rβ的免疫细胞化学检测以及RT-PCR分析。
在胎儿和成年/青少年卵巢中,从原始卵泡阶段开始,卵泡的卵母细胞和颗粒细胞中均有强至中度的OSM免疫细胞化学染色。OSM-Rβ主要在卵母细胞中检测到。通过RT-PCR分析检测到了OSM和OSM-Rβ RNA的转录本。
OSM及其受体在胎儿和女性卵巢组织中的表达表明,OSM在人类原始卵泡的生长启动中可能发挥作用。
