今天3分钟我们来聊聊干细胞复制眼角膜
from 源于细胞BioInsid的个人播客
角膜内皮细胞一旦受损,就会导致水肿、混浊,最终失明。传统手段只能依赖角膜移植,但全球供体严重不足,每70个患者里,只有1人能等到角膜。再生细胞疗法带来了新希望:科学家从一个供体角膜提取少量细胞,在实验室扩增,能获得 1000倍以上的治疗剂量。医生只需去除病变细胞,再注射这些培养好的细胞,患者俯卧3小时后即可回家。在日本,首个获批疗法 Vyznova,10年随访中 83.7% 的患者视力稳定恢复,排斥率也远低于传统移植。Emmecell 和 Aurion 等公司还在推进新技术,比如磁性定位和细胞冷冻保存,让疗法更安全、更普及。一句话:再生细胞疗法不依赖角膜买卖,更不会有“黑市风险”,它正在让角膜失明患者真正重见光明。前往小宇宙评论区与主播互动
