Clonal propagation of plants by runners is based on meristematic activity of the differentiated cells of the plants . 植物通过长匐茎的无性繁殖基于植株分化细胞的分生活性
Cell cycle control , 细胞生长分化细胞凋
The numbers of differentiated cells induced by bmp - 2 , atra , vd3 and dex were not correlative with the amount of ra receptor mrna Bmp一2 、 atra 、 vd3和dex诱导形成的分化细胞量与ra受体mrna表达量之间不存在相关性。
Still , approximately one third of patients return with after - cataracts , caused by undifferentiated cells ? stem cells ? that are inadvertently left behind during surgery 不过,仍有约三分之一的病人因未分化细胞(干细胞)造成的白内障后遗症而再度求医。
Vascular plants plants containing differentiated cells forming conducting tissue ( vascular tissue , also known as fascicular tissue ) , which comprises the xylem and phloem 维管植物:具有能够形成体内运输组织(维管组织:包括木质部和韧皮部)的分化细胞的植物。
