摘要: 目的:研究甲醛对人绒毛膜滋养细胞活性及分泌功能的影响。方法:收集9例早孕人工流产患者的绒毛组织,原代培养绒毛膜滋养细胞,分别加入50,100,150,200 μmol/L甲醛处理细胞48 h。用Cell Counting Kit-8(CCK-8)检测滋养细胞活性、放射免疫法检测人绒毛膜促性腺激素(hCG)水平。以DMEM/F12培养液为对照。结果:与对照组比较,100,150,200 μmol/L甲醛染毒组的细胞活性显著抑制,差异有统计学意义(均P<0.05);各组之间hCG水平差异无统计学意义(P>0.05)。结论:甲醛达到一定浓度时(≥100 μmol/L)对人绒毛膜滋养细胞的细胞活性有毒性作用。

Abstract: Objective:To investigate the toxic effect of formaldehyde on the cellular viability and secretory function of human cytotrophoblasts at the first trimester stage. Methods:Human villi were obtained from nine patients undergoing abortion with the signed consent form. Cytotrophoblasts were extracted and cultured in vitro in medium, and then treated with formaldehyde(50,100,150,200 μmol/L) for 48 hours. The cellular viability of cytotrophoblasts was determined with Cell Counting Kit (CCK-8), while the level of human chorionic gonadotropin(hCG) in medium was assayed with radioimmunoassay. DMEM/F12 medium was used as the negative control. Results:The cellular viabilities of cytotrophoblasts in three treatment groups with ≥100 μmol/L of formaldehyde was significantly decreased than that in the control group (P<0.05). The differences of the hCG levels among those groups were not significant(P>0.05). Conclusions:Formaldehyde at a higher dose (≥100 μmol/L) may reduce the cellular viability of cytotrophoblasts.
