Protocol for establishing genetically engineered murine lung organoids mimicking cell plasticity and regeneration

Lung endothelial cells (LuECs) play crucial roles in lung regeneration and support lung organoids (LOs). However, detailed guidelines for LO culture using LuECs have not been reported yet. Here, we present an efficient protocol for generating and culturing murine LOs that mimic regeneration. We describe steps for the isolation of LuECs and lung epithelial cells, followed by LO culture. We also describe how to establish genetically engineered LOs using viral transduction. For complete details on the use and execution of this protocol, please refer to Kim et al.¹^,².
