1382-诱导多能干细胞分化为灵长类精原细胞

from 聊聊Sci

这份研究报告阐述了科学家如何利用人类和恒河猴的诱导多能干细胞 (iPSCs),在实验室中成功诱导分化出精原细胞。研究人员开发了一种异种重组睾丸 (xrTestis) 系统,将干细胞衍生的生殖细胞与小鼠体细胞结合并植入免疫缺陷小鼠体内。实验结果显示,这些诱导细胞能够发育至减数分裂早期,并在转录组和表型上高度还原体内真实的生殖细胞特征。此外,该平台还成功模拟了prepachytene piRNA 的生物合成过程,这对于保护生殖细胞基因组完整性至关重要。这项成果为研究灵长类动物生殖系发育提供了新模型,标志着体外配子发生技术取得重大进展。该系统不仅有助于揭示男性不育的分子机制,也为未来开发再生医学疗法奠定了基础。References:Whelan E C, Guo M, Yokomizo R, et al.
