摘要:目的研究甲醛对BM—MSCs的遗传毒性,从而为甲醛导致白血病的发作提供生物学依据。方法采用噻唑篮比色(Mrrr)法检测BM—MSCs的增殖活性;用彗星、KCI—SDS沉淀、姐妹染色单体互换(SCE)和微核(MN)柃测甲醛对BM—MSCs的遗传毒忡效应。结果75~200μmol/L。甲醛可呈剂量依赖抑制BM—MSCs的增殖(P〈0.01),诱导BM—MSCsDNA断裂效应呈现先增高后降低趋势,在125μmol/L时,达到峰值,其中75~150μmol/L甲醛作用较对照组显著升高(P〈0.01);甲醛在≥125μmol/L,时可以明显引起BM—MSCsDNA-蛋白交联(DPCs)、SCE和MN的形成,较对照组显著升高(P〈0.01)。结论甲醛可抑制BM—MSCs的增殖活性,并且对BM—MSCs具有一定的遗传毒性效应。
Objective To find potential genotoxic effect of formaldehyde on BM-MSCs, for providing the biological evidence for the formaldehyde to lead to leukemia. Methods Proliferation activity was measured by MTT assay; Genotoxic effect was detected by comet assay, KC1-SDS precipitation assay, sister chromatid exchange (SCE) test and micronucleus (MN) test. Results 75 - 200 μmol/L formaldehyde can inhibit the BM-MSCs proliferation in a dose-dependent manner (P 〈0. 01 ) ; DNA strand breakage increased gradually at increasing concentrations below 125 μmol/L, however, when formaldehyde concentration was over 125 μmol/L, DNA strand breakage decreased. There were significant rises in 75 - 150 μmoL/L formaldehyde groups compared with control group (P 〈 0. O1 ) ; In- duction of DNA-protein crosslinks ( DPCs), SCE and MN in /〉 125 μmol/L formaldehyde groups were significant higher than in control group (P 〈 0. 01 ). Conclusions Formaldehyde can inhibite the BM-MSCs proliferation ac- tivity, and have a genotoxic effect on the BM-MSCs.
