Isolation and identification of human fetal kidney - derived mesenchymal - like stem cells and their differentiation to adipocyte and osteoblast 人胎肾间充质样干细胞分离鉴定及其向脂肪和成骨细胞的分化
2.
These fetal kidneys ( from a gestation estimated at 25 weeks in the second trimester ) demonstrate a normal cut surface . note the pelvis and calyces . note the well - defined corticomedullary junctions 这是妊娠中期，估计为25周胎儿肾。切面正常，可见肾盂、肾盏，皮质、髓质分界清楚。
3.
The difference between these 2 groups was statistically significant . conclusions the results suggested that the genesis of nephroblastoma is relevant to the retarded differentiation of fetal kidney 结果肾母细胞瘤与早期胚胎肾在组织形态上有相似之处； 22例肾母细胞瘤瘤旁肾组织中6例见肾源性剩余存在， 30例非肿瘤成熟肾组织中仅1例见肾源性剩余存在。
