Differentiating stem cells into specific cell types is a critical step in regenerative medicine and disease modeling. Generating lung epithelial cells from stem cells offers promising avenues for studying s, drug screening, and potentially developing cell-based therapies for respiratory disorders. In this protocol, we will outline a comprehensive method to differentiate stem cells into lung epithelial cells. This protocol can be applied to various stem cell sources, including induced pluripotent stem cells (iPSCs) or embryonic stem cells (ESCs).
Thaw stem cells, culture on Matrigel/Geltrex-coated plates, and maintain them in an appropriate stem cell medium. Passage the cells when they reach 70-80% confluence. Change the stem cell culture medium daily.
Detach the stem cells using EDTA and culture them as aggregates (EBs) in suspension using low-attachment plates. After 3 days, plate the EBs on Matrigel/Geltrex-coated plates in definitive endoderm medium. Change the medium daily for 5-7 days.
Switch to anterior foregut endoderm medium and culture for 3-4 days.
Switch to lung progenitor medium for 6-8 days. Monitor cell morphology and marker expression (e.g., NKX2.1, FOXA2) under a microscope or by immunostaining.
Switch to a maturation medium. Optimize the culture conditions for desired lineage-specific differentiation (e.g., alveolar type II cells, ciliated cells) based on your research needs.
The protocol outlined here provides a robust method for differentiating stem cells into lung epithelial cells, which can be a valuable resource for studying lung development, modeling diseases, and developing potential therapies. The differentiation process involves multiple steps and the use of various growth factors to guide the cells along the desired lineage.
