Embryonic Stem Cells

25.8K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

4.5K
Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

科学领域:

  • 胚胎学
  • 人工智能
  • 生殖医学

背景情况:

  • 在辅助生殖技术 (ART) 中,胚胎质量评估对于选择可行的胚胎和确定最佳移植时间至关重要.
  • 目前的人工智能工具可以自动评估,但缺乏对未来胚胎发育的预测能力.
  • 人工智能系统需要能够预测胚胎形态的变化.

研究的目的:

  • 开发一个能够预测胚胎形态动态的AI系统.
  • 帮助胚胎学家在早期评估和选择胚胎进行移植.
  • 预测胚胎的未来形态变化超出目前的观察能力.

主要方法:

  • 人工智能系统分析过去的胚胎发育 (2小时) 以预测未来的形态变化 (长达23小时).
  • 使用卷积式LSTM层的新型预测模型使胚胎发育的递归预测成为可能.
  • 该模型分析了之前的视频序列变化以预测形态.

主要成果:

  • 人工智能系统准确地预测了胚胎在分裂 (2日) 和胚胎 (4日) 阶段的发育.
  • 提供了关于细胞分裂过程和胚胎细胞形成的宝贵见解.
  • "转移"类胚胎的预测显示,与"避免"类胚胎相比,细胞膜更清晰,扭曲程度更小.

结论:

  • 人工智能系统为胚胎质量提供了早期见解,有助于对转移和避免的评估.
  • 胚胎学家可以利用预测来想象和理解胚胎的形态变化.
  • 提高图像质量可以提高这种预测性AI方法的临床相关性.
