Patches of cells, which at the light-microscope level appear to be epithelial, persist for several months in cultures of normal mouse colon. Ultrastructural studies showed that these cells were nerve-associated and were probably derived from the Schwann cell-satellite cell group. True epithelial cells all died out within the first 2 wk of culture, and epithelial cell lines could not be established.
在光学显微镜水平看似上皮细胞的细胞斑块，在正常小鼠结肠培养物中持续存在数月。超微结构研究表明，这些细胞与神经相关，可能源自雪旺细胞 - 卫星细胞群。真正的上皮细胞在培养的前2周内全部死亡，无法建立上皮细胞系。
