胶原质

The bodies have much greater potential to regulate spermatogonial stem cell proliferation and differentiation. The dosage of GFRα1 mRNA produced by undifferential spermatogonial cells regulates the signal transduction of glial cell-derived neurotrophic factor so as to regulates the direction of spermato gonial stem cells: at a low level, spermatogonoial stem cell favors differentiation; at a high level, spermatogonial stem cell favors self-proliferation.

GFRαl在小鼠生精恢复过程中以剂量相关性调控著胶质细胞源性神经营养因数资讯传人，从而调控著精原干细胞的去向：高剂量时诱导其增殖，低剂量时诱导其分化。

In contrast, 11/15 primary glioblastomas contained a significant CD133 subpopulation that displayed neurosphere-like, nonadherent growth and asymmetrical cell divisions yielding cells expressing markers characteristic for all three neural lineages.

相反，15个原代胶质母细胞瘤中有11个含有明显的CD133阳性亚群，呈神经球样，非附着性生长和非对称性细胞分裂，后者产生表达所有三种神经细胞系的特征标志物的细胞。15

Results as follows;(1) At 25th week of fetal age, the staining intensity and cell density almost equalled to that at birth in cervical spinal cord, brainstem, hippocampus, and vermis of cerebellum; while there are only 1/4 cell densities in cerebral cortex.
