Fig. 7From: Interactions between rat alveolar epithelial cells and bone marrow-derived mesenchymal stem cells: an in vitro co-culture modelTransmission electron micrographic images of AECs in direct contact with BMSCs on day 14. a Type II-like epithelial cells observed in this preparation. b Freshly isolated type II AECs. The lamellar bodies that were observed in the freshly isolated cells were also observed in some of the epithelial cells in a (a, b white arrow heads). c A magnified image of the cellular contact observed in the black rectangle shown in a. The black arrow heads indicate contacts between the epithelial and mesenchymal cells. mv microvilliBack to article page
