我们这里用过,我还见过师兄们使用Y-27632之后干细胞和未使用y-27632的生长状态的对比。效果是很 明显的,使用Y-27632处理后的挑传后的干细胞生长状态比未使用同样使用挑传方法传代的干细胞生长状态好很多。另外,使用Y-27632需要注意其处理时间,时间太长是对干细胞有害的。如果你想详细了解Y-27632对干细胞的作用,推荐你看下下面几篇文章:

0 i* f( r6 B' jSince their derivation, human embryonic stem (hES) cells have been used for a variety of applications including developmental biology, pathology, chemical biology, genomics, and proteomics. However, their most important potential application is the generation of cells and tissues, which can be used for cell-based therapies. One of the main drawbacks of hES cell culture is that they are particularly sensitive to dissociation, which is required for passaging, expansion, cryopreservation, and other applications. Recently, it has been discovered that an inhibitor of Rho kinase (ROCKi; Y-27632) increases the survival rate of dissociated, single hES cells. This breakthrough has allowed new methods in hES cell culture to be developed, with the promise of increasing hES cell numbers into the realm of clinical relevance. In our studies demonstrating that ROCKi dramatically increases hES cell cryopreservation efficiency, we have observed that ROCKi treatment does not decrease hES cell's susceptibility to apoptosis. Rather, we hypothesize that ROCKi treatment desensitizes single hES cells to their environment reducing the odds that individual cells will undergo anoikis.( o& T% T2 j; D2 C5 J
