评估iMSCs在受损气管中的生存和分化.
调查iMSCs作为一种可行的替代方案,用于用于气管重建的非生物降解网格.

主要方法:

iMSCs是通过神经细胞从人类诱导的多能干细胞 (hiPSCs) 生成的.
iMSCs用原海绵覆盖的聚烯网移植到免疫缺陷的老鼠气管缺陷中.
移植后评估了细胞存活率和冠原体分化标记物 (SOX9,II型原体).

主要成果:

移植后的IMSC在老鼠气管缺陷中在移植后的4周和12周生存.
人类核抗原 (HNA) 阳性细胞表达了SOX9并被II型原体包围,表明了原体的分化.
观察到软骨样组织再生的证据,支持iMSC的潜力.

结论:

移植的iMSCs可以在气管缺陷中生存并分化为chondrogenic细胞.
iMSC移植促进气管软骨再生,为呼吸道重建提供了一个有前途的策略.
这种方法可以克服当前人工气管材料的局限性,特别是在儿科应用中.

iPS Cell Differentiation

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
