摘要
体外培养145-170gm牛腔前卵泡能够形成卵泡腔已有人报道,但体外培养50-70μm的牛初级卵泡能否发育成腔仍没有报道。为了建立适合牛初级卵泡体外生长发育的培养体系,同时进一步揭示牛腔前卵泡体外发育的相关机制,本实验以屠宰场获取的牛卵巢为材料,以机械分离法获取直径50-70μm的牛初级卵泡,以α-MEM为基础培养基,调整不同浓度促卵泡素(FSH)、促黄体素(LH)和雌二醇(E2)激素配比以及优化碱性成纤维生长因子(bFGF)和表皮生长因子(EGF)添加量等试验,使用胶原包被的三维培养方法对牛初级卵泡进行体外培养13或21天(d),观察卵泡直径以及成腔的变化,并用Real-Time PCR检测卵泡发育及成熟相关基因:芳香化酶(CYP19A1)、抗缪勒激素(AMH)、生长分化因子9(GDF-9)、骨形成蛋白15(BMP-15)以及m型转化生长因子p受体(TGFβR3)的表达。结果发现,以α-MEM为基础培养基,0.25μg/mL FSH+5IU/mL LH+0.1μg/mL E2+50ng/mL bFGF组以及FSH+LH+E2+bFGF和25ng/mL EGF联合处理组卵泡直径在体外培养21d时显著高于其他组(p<0.05),并且在培养第19d和17d形成小的卵泡腔,成腔率分别为16.7%和33.3%。卵泡发育、成熟相关基因CYP19A1,AMH, GDF-9,BMP-15和TGFβR3的表达也有显著变化。综上,我们建立了一套有效的体外促进牛初级卵泡生长和成熟的培养体系,即α-MEM+FSH(0.25μg/mL)+LH(5IU/mL)+E2(0.1μg/mL)+bFGF(50ng/mL)+EGF(25ng/mL);
     MicroRNA(miRNA)是近年来发现的一类长度为20-25nt的小干扰RNA,它通过对基因的转录后调控,在细胞的增殖、分化、凋亡等方面发挥重要作用。本实验在之前牛初级卵泡培养的基础上,发现miR-27a在牛卵巢中表达较高,但由于条件限制,我们利用小鼠模型来探讨miR-27a对颗粒细胞功能的影响。我们发现,miR-27a在小鼠腔前卵泡颗粒细胞中表达较高,但在有腔卵泡颗粒细胞中表达明显下降。因此,本实验通过体外高效转染技术,将miR-27a模拟物(mimics)和抑制剂(inhibitor)转入小鼠颗粒细胞中,利用Real-Time PCR、流式细胞术等实验方法检测miR-27a和相关基因的表达以及观察其对颗粒细胞增殖和激素分泌的影响。结果发现:miR-27a有促进颗粒细胞凋亡、抑制颗粒细胞增殖、抑制颗粒细胞分泌雌激素的功能,它可能是通过下游的靶基因CREB1来影响颗粒细胞的凋亡和雌激素分泌,但具体机理还需进一步验证。
Successful antral formation in vitro from bovine preantral follicles (145-170μm) has been described previously, but antrum formation from the primary follicle (50-70μm) has not yet been achieved in vitro. In order to establish the optimal bovine primary follicle culture system in vitro and investigate the related mechanisms. Primary follicles (50-70μm) were dissected from bovine ovaries, and cultured in a three-dimensional culture system for13or21days in alpha-minimum essential medium (a-MEM). Various treatments including follicle stimulating hormone (FSH), luteinizing hormone (LH),17β-estradiol (E2), basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF) were tested. The follicular diameter and antrum formation rate were recorded, and follicular maturation markers (P450aromatase, CYP19A1; anti-Mullerian hormone, AMH; growth differentiation factor-9, GDF-9; bone morphogenetic protein-15, BMP-15; and type III transforming growth factor P receptor, TGFβR3) were analyzed by Real-Time RT-PCR. After21days of culture under each treatment condition, the follicular diameter was significantly enlarged in the presence of FSH+LH+E2+bFGF or FSH+LH+E2+bFGF+EGF (p<0.05). An addition of50ng/mL bFGF or bFGF+25ng/mL EGF initiated antrum formation by day19and day17of culture, and the antral cavity formation rate was16.7%and33.3%by21days of culture, respectively. The expression of follicular maturation markers (CYP19A1, AMH, GDF-9, BMP-15and TGFPR3) was significantly altered. We conclude that addition of50ng/mL bFGF+25ng/mL EGF to media containing FSH+LH+E2turned out to be the most effective optimized culture conditions to support the growth and maturation of bovine primary follicles in vitro.
     MicroRNAs (miRNAs) are a class of small (20-25nt) non-coding RNAs which function in gene post-transcriptional regulation with important roles in cell proliferation, differentiation and apoptosis. Based on our previous bovine primary follicle culture study, we observed that expression of miR-27a was abundant in bovine ovary. We investigated the molecular function of miR-27a in mouse granulosa cell. Our results showed that expression of miR-27a in mouse preantral follicles granulose cell was higher than the expression in antral follicles granulose cell. After transfected miR-27a mimics and its inhibitor into mouse granulosa cells, we found that miR-27a played a important role in suppressing granulosa cells proliferation, promoting granulosa cell apoptosis and inhibiting estrogen secretion, and these effects were mainly by targeting transcriptional factor CREB1.
