Abstract

Hyperthermia along with hydrocortisone (HC) are proven teratogens that can negatively influence embryo development during early pregnancy. Proliferation of cells is one of the main developmental processes during the early embryogenesis. This study was focused on testing the effect of elevated temperature and HC addition on proliferation of cells in in vitro cultures. The V79-4 cell line was treated with HC and cultured in vitro at 37 °C or 39 °C, respectively. To reveal the effect of both factors, the proliferation of cells cultured under different conditions was evaluated using various approaches (colony formation assay, generation of growth curves, computation of doubling times, and mitotic index estimation). Our results indicate that a short-term exposure to elevated temperature slightly stimulates and a long-term exposure suppresses cell proliferation. However, HC (0.1 mg/ml) acts as a stimulator of cell proliferation. Interestingly, the interaction of HC and long-term elevated temperature (39 °C) exposure results in at least partial compensation of the negative impact of elevated temperature by HC addition and in higher proliferation if compared with cells cultured at 39 °C without addition of HC.

高温和氢化可的松对成纤维细胞增殖的影响
高热和氢化可的松(HC)已被证实是致畸剂,会对怀孕早期的胚胎发育产生负面影响。细胞增殖是早期胚胎发育的主要过程之一。本研究的重点是测试温度升高和添加 HC 对体外培养细胞增殖的影响。用 HC 处理 V79-4 细胞系,并分别在 37 ℃ 或 39 ℃ 下进行体外培养。为了揭示这两种因素的影响,我们采用多种方法(菌落形成检测、生成生长曲线、计算倍增时间和有丝分裂指数估算)评估了在不同条件下培养的细胞的增殖情况。我们的结果表明,短期暴露于高温会轻微刺激细胞增殖,而长期暴露于高温则会抑制细胞增殖。然而,碳氢化合物(0.1 毫克/毫升)会刺激细胞增殖。有趣的是,HC 和长期暴露于高温(39 °C)的相互作用至少部分补偿了高温的负面影响,与在 39 °C下培养而不添加 HC 的细胞相比,增殖率更高。
