Person-in-charge Differentiation of tissue-specific stem/progenitor cells has a role in homeostasis and repair. We previously isolated progenitor cells from adult human lung tissues, which had the ability to generate alveolar epithelial type II (ATII) cells (Fujino N, et al. Lab Invest 2011;91:363). However molecular mechanisms underlying the progenitor cell differentiation remain poorly understood. To address this question, we carried out a phenotypic screen using a small molecule library consisting of stem cell modulators and a diverse set of kinase inhibitors. We identified an inhibitor of AXL receptor tyrosine kinase, which drove the lung progenitor cells towards ATII cells via mesenchymal-to-epithelial transition. Our study reveals that AXL kinase acts as a barrier in the epithelial differentiation of human lung progenitor cells.
