We performed comparative analysis of paracrine activity of neuronal and glial progenitors derived from induced pluripotent stem cells under conditions of hypoxia modeled by addition of cobalt dichloride. Neuronal and glial progenitors produced neuroprotective and neurotrophic effects on SHSY-5Y neuroblastoma cells in co-culture during the post-hypoxic recovery and reduced the number of apoptotic and necrotic cells. Moreover, they produced a neurotrophic effect and promote the formation and growth of neurites in neuroblastoma cells. The paracrine effect of glial progenitors was more pronounced, which can be explained by more intensive expression and secretion of neurotrophic factors in these cells.
我们在模拟缺氧的条件下,对比分析了诱导多能干细胞来源的神经元和神经胶质前体细胞的旁分泌活性。在缺氧后恢复过程中,神经元和神经胶质前体细胞在共培养中对 SHSY-5Y 神经母细胞瘤细胞产生了神经保护和神经营养作用,减少了凋亡和坏死细胞的数量。此外,它们还产生了神经营养作用,并促进神经母细胞瘤细胞中神经突的形成和生长。神经胶质前体细胞的旁分泌作用更为明显,这可以解释为这些细胞中神经营养因子的表达和分泌更为活跃。
