单细胞是必须要做的

  • 细胞系没有做单细胞的必要,除非是Perturb-seq;
  • 其次就是Patient或Mouse derived Organoid了;
  • 最后就是纯in vivo的Mouse,这个周期长门槛高;

 

重点来讲一下肠道类器官

Hans clever,鼻祖,YT上有ibiology的教学,可以看一看;

Gastrointestinal Organoid Derivation and Culture

L-WRN细胞系:

  • Wnt3a - Wnt激活剂,stem cell
  • R-spondin3 - 辅助剂,提高Wnt的敏感度
  • Noggin - BMP抑制剂,防止分化

ER medium:

  • EGF - promoting proliferation
  • R-spondin3 - 辅助剂,提高Wnt的敏感度

什么是conditioned media?这里的条件是指引分化的条件。

In the strictest sense, the cell secretome (conditioned media) refers to the collection of proteins that contain a signal peptide and are processed via the endoplasmic reticulum and Golgi apparatus through the classical secretion pathway.
