The present invention provides ocular cells, genetically modified by a CRISPR system targeting the expression of B2M for ocular cell therapy. The invention further provides methods of generating an expanded population of genetically modified ocular cells, for example limbal stem cells (LSCs) or corneal endothelial cells (CECs), wherein the cells are expanded involving the use of a LATS inhibitor and the expression of B2M in the cells has been reduced or eliminated. The present invention also provides cell populations, preparations, uses and methods of therapy comprising said cells.
本发明提供了一种通过CRI
SPR系统靶向B2M表达进行
基因修饰的眼部细胞,用于眼部细胞疗法。该发明进一步提供了一种生成扩增的
基因修饰眼部细胞群体的方法,例如角膜缘干细胞(LSCs)或角膜内皮细胞(C
ECs),其中这些细胞在扩增过程中涉及使用
LATS抑制剂,并且这些细胞中的B2M表达已经减少或消除。本发明还提供了细胞群体、制剂、用途和包括上述细胞的治疗方法。
