[Abstract]  Erythroid-Myeloid-Lymphoid cells (EML) are a multipotent haematopoietic cell line of mouse bone marrow origin capable of long-term maintenance in vitro in the presence of SCF (stem cell factor) (Tsai et al., 1994). The self-renewal capacity of the EML cell line is conferred by the presence of a dominant-negative retinoic acid receptor (RAR) originally delivered by retroviral transduction (Tsai et al., 1994), which arrests cells at an early progenitor stage blocked from normal progression into myeloid differentiation. The presence of the RAR trans-gene does not interfere with erythroid differentiation, and it is possible to capture a low percentage of early erythroid, but not myeloid, committed cells in maintenance cultures (Pina et al., 2012; Ye et al. ... [摘要]  红细胞 - 髓样淋巴细胞(EML)是能够在SCF(干细胞因子)存在下在体外长期维持的小鼠骨髓来源的多潜能造血细胞系et al。,1994)。 EML细胞系的自我更新能力通过最初通过逆转录病毒转导递送的显性 - 负性视黄酸受体(RAR)的存在(Tsai等人,1994)来赋予,其捕获细胞在阻止从正常进展成骨髓分化的早期祖细胞阶段。 RAR转基因的存在不干扰红细胞分化,并且可能在维持培养中捕获低百分比的早期红细胞而不是骨髓,定型细胞(Pina等人, 2012; Ye等人,2005)。通过使用高剂量的视黄酸(RA),细胞可以被驱动进入粒细胞/嗜中性粒细胞分化,其克服了分化阻断。应当注意,RA的这些药理学剂量与红细胞分化不相容,因此在相同测定中获得稳定的红细胞和骨髓分化是不可行的。实际上,在CFC测定中作为混合谱系评分的集落是未分化和类红细胞的混合物(Tsai et al。,1994)。然而,在如下所述的确定的细胞因子条件下的液体培养中可以获得稳定的单谱系红细胞和嗜中性粒细胞分化。
