To clarify the mechanisms of intrauterine platelet-rich plasma (PRP) infusion that support embryo implantation in in vitro fertilization treatment.
Blood and endometrial samples were collected from four infertile women. Human endometrial stromal cells (HESCs) were cultured and passaged equally into four cell culture dishes in each patient. Two were treated with PRP twice, and the other two were treated with vehicle. Subsequently, two cultures with and without PRP were decidualized with 8-bromoadenosine 3',5'-cyclic AMP and progesterone for 5 days.
The gene expression in undifferentiated or decidualized HESCs with and without PRP was compared. In the microarray analysis, 381 and 63 differentially expressed genes were detected in undifferentiated and decidualized HESCs, respectively. In the undifferentiated HESCs, PRP was found to promote the gene expression associated with cell growth, tissue regeneration, proinflammatory response, and antibiotic effects. In decidualized HESCs, PRP was found to attenuate the gene expression involved in cell proliferation and inflammation by inhibiting the expression of phosphoinositide 3-kinase signaling.
Platelet-rich plasma regulates the reprogramming of cell proliferation and inflammation depending on menstrual cycle phases in an appropriate manner, suggesting that PRP has the potential to increase endometrial thickness in the proliferative phase and improve immune tolerance in the secretory phase.
阐明在体外受精治疗中,宫腔内输注富血小板血浆(PRP)支持胚胎着床的机制。
从4名不孕女性中采集血液和子宫内膜样本。培养人子宫内膜基质细胞(HESC),并将每位患者的细胞均等传代至4个细胞培养皿中。其中两个培养皿用PRP处理两次,另外两个用赋形剂处理。随后,用8-溴腺苷3',5'-环磷酸腺苷和孕酮将两个含PRP和不含PRP的培养物进行蜕膜化处理5天。
比较了有无PRP的未分化或蜕膜化HESC中的基因表达。在微阵列分析中,未分化和蜕膜化的HESC中分别检测到381个和63个差异表达基因。在未分化的HESC中,发现PRP可促进与细胞生长、组织再生、促炎反应和抗生素作用相关的基因表达。在蜕膜化的HESC中,发现PRP通过抑制磷酸肌醇3激酶信号通路的表达来减弱参与细胞增殖和炎症的基因表达。
富血小板血浆根据月经周期阶段以适当方式调节细胞增殖和炎症的重编程,提示PRP有潜力在增殖期增加子宫内膜厚度,并在分泌期提高免疫耐受性。
