Stem cell niche in the lung

How do lung progenitors recognize stem cell niches, and what cell-cell interactions mediate normal repair?

Tags (Keywords associated with the idea)

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? : Compelling Question (CQ)

Details on the impact of addressing this CQ or CC :

Research on the stem cell-niche interaction will enhance our understanding of stem cell behavior, enable manipulation of stem cell activity and differentiation potential, and facilitate the development of stem cell-based therapy.

Feasibility and challenges of addressing this CQ or CC :

Developing novel models for in vitro 3D culture and in vivo transplantation assays will facilitate the progress.


Recent advances have identified and characterized several lung progenitor cell types. However research gaps remain on understanding the interaction of stem cells with the niche, and how the microenvironment impacts on the stem cell activity during injury/repair.
