胶质细胞源性神经营养因子 (GDNF) 家族的配体是多种细胞类型发育和存活的营养因子,但它们对非神经元干细胞的影响尚不清楚。我们检查了神经营养因子对从成人骨骼肌中分离出的候选干细胞群的作用。当生长成球形时,这些细胞表达 GDNF、persephin、GFR-α2、GFR-α4(神经营养因子受体)和 Ret 的 mRNA。将这些细胞暴露于神经营养因子可通过增加细胞增殖来显着增加细胞数量。添加视黄酸后,细胞退出细胞周期,形成细突,并对 βIII-微管蛋白产生免疫反应,同时 Ret mRNA 表达下降,但 GFR-α2 mRNA 水平没有变化。 Neurturin 诱导这些 βIII-微管蛋白阳性细胞上的突起生长。因此,Neurturin 可能有益于使用这些从成人肌肉中分离的多能细胞进行神经学应用中的自体移植。
Ligands of the glial cell line-derived neurotrophic factors (GDNF)-family are trophic factors for the development and survival of multiple cell types, however their effects on non-neuronal stem cells are unknown. We examined the action of neurturin on a candidate stem cell population isolated from adult skeletal muscles. When grown as spheres, these cells expressed mRNAs for GDNF, persephin, GFR-α2, GFR-α4 (neurturin receptor), and Ret. Exposure of these cells to neurturin significantly augmented cell numbers via increased cell proliferation. After addition of retinoic acid, the cells exited the cell cycle, developed thin processes, and became immunoreactive for βIII-tubulin, while Ret mRNA expression decreased, without changes in the level of GFR-α2 mRNA. Neurturin induced an outgrowth of processes on these βIII-tubulin positive cells. Neurturin may therefore be beneficial in the use of these multipotent cells isolated from adult muscles for autologous transplants in neurological applications.
