Disclosed are certain heterocyclic organic compounds that inhibit mitochondrial respiration and also lead to the maintenance of pluripotency of human embryonic stem cells in culture, even in the presence of oxygen. Exemplified are compounds, such as substituted 5-aminotetrazoles, which are reversible mitochondrial inhibitors. The pluripotency of the stem cells after culture is verified by the overexpression of pluripotent stem cell markers, exemplified by at least one of the genes NANOG, OCT4, and SURVIVIN after periods of culture in ambient oxygen.
已公开的某些杂环有机化合物可抑制线粒体呼吸,还能使培养中的人类胚胎干细胞保持多能性,即使在有氧的情况下也是如此。例如,取代的 5-
氨基
四唑化合物是可逆的线粒体
抑制剂。培养后干细胞的多能性通过多能干细胞标志物的过度表达来验证,例如,在环境
氧气中培养一段时间后,多能干细胞标志物中至少有一种
基因NANOG、OCT4和SURVIVIN。
