查询词典 stem cells

Of stem cells created in this way have only one parent, they are immunologically simpler than normal embryonic cells—in other words they have a smaller variety of the proteins that trigger rejection.

也许，这一方法除了具有道德优势以外，它还具有医疗优势。因为这样产生出来的干细胞只是来自一方的遗传，相对普通胚胎干细胞他们要面对的免疫排斥问题要简单一些，换言之，就是产生排斥的蛋白质种类要少一些。

Bone marrow mesenchymal stem cells could differentiate into osteoblasts, adipocytes and neural like cells with osteoblast inductor (β-sodium glycerophosphate, dexamethasone, vitamin C), lipoblast inductor (dexamethasone, 3-isobutyl-1-methylxanthine, bovine insulin, indometacin) and serum-free medium inductor (dimethyl sulphoxide, butylated hydroxyanisole) respectively. Osteoblast marker (alkaline phosphatase, osteocalcin mRNA, calcium node), adipocyte marker (lipid droplet, PPAR γ-2mRNA) and neural cell-like marker (nissl body, neuron specific enolase, neurofilament protein) were respectively determined by the immunohistochemical method, polymerase chain reaction and immunocytochemical method.
