ETV2およびNKX3.1の直交活性化を介したヒト血管オルガノイド生成プロトコル

Vascular organoids (VOs) are 3D multicellular constructs that model vascular development and function. Here, we present a protocol to generate VOs from human induced pluripotent stem cells via orthogonal activation of transcription factors. We describe steps for inducing endothelial and mural lineages independently using doxycycline-inducible expression of ETV2 and NKX3.1. This protocol enables efficient formation of functional VOs within 5 days, streamlining conventional techniques and supporting applications in vascular biology, tissue engineering, and regenerative medicine. For complete details on the use and execution of this protocol, please refer to Gong et al.¹.
