Fig. 2From: Inflammatory responses in the initiation of lung repair and regeneration: their role in stimulating lung resident stem cellsTissue-resident stem cells for repair and regeneration after lung injury and acute inflammation. a Schematic image of the roles of epithelial stem/progenitor cells during lung injury. b AEPCs can differentiate to AT II cells in vitro culture. c Alveolar epithelial progenitor cells (AEPCs; arrowheads) express both CD90 (mesenchymal marker) and pro-SPC (AT II marker) and are localized in the regions of hyperplasia of AT II cells in the lungs of IPF patientsBack to article page
