EPS and iPS Cells in Disease Research

2.8K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

科学领域:

  • 产科和妇科 产科和妇科
  • 心血管生物学 心血管生物学
  • 干细胞生物学 干细胞生物学

背景情况:

  • 孕前影响全球5-7%的怀孕,其中母亲内皮功能障碍是关键因素.
  • 了解孕前的发病因子受限于患者特异性内皮细胞的稀缺性,用于研究.
  • 需要一个强大的体外模型来研究患儿特异性的子宫内皮功能障碍在孕前.

研究的目的:

  • 建立一个可再生的,针对患者的体外内皮细胞 (EC) 模型,用于产前的研究.
  • 研究不同妊娠期血清对内皮细胞功能的影响.
  • 在患者特定的基础上,使预先怀孕症内皮功能障碍的机制研究成为可能.

主要方法:

  • 从正常紧张妊娠中诱导的多能干细胞 (iPSC) 分化为内皮细胞 (EC).
  • 来自患者的iPSC-EC暴露于来自正常压力怀孕,先兆怀孕和非怀孕对照的聚合血清.
  • 评估了内皮功能,包括氧化 (NO) 释放,细胞迁移,管道形成和活力.

主要成果:

  • 与对照人群相比,先血清显著减少了氧化 (NO) 的释放.
  • 内皮细胞迁移和管形成受到预先塞血清的影响.
  • 细胞活力不受任何血清治疗的影响,结果在患者特定的线条中一致.

结论:

  • 来自患者的iPSC-ECs为研究子宫前提供了一个新的模型.
  • 这种模型有助于探索母体内皮质健康状况和孕前的循环因素.
  • 该模型有助于剖析产前时内皮功能障碍的机制.
