Interactions between rat alveolar epithelial cells and bone marrow-derived mesenchymal stem cells: an in vitro co-culture model

摘要

Background Bone marrow-derived mesenchymal stem cells (BMSCs) reduced the severity of acute lung injury after transplantation in multiple experimental studies, and several paracrine soluble factors secreted by the cells likely contribute to their therapeutic effect. The direct interactions between BMSCs and alveolar epithelial cells (AECs) may be an important part of their beneficial effects. Therefore, we assessed the interactions between BMSCs and AECs using a co-culture model of these two cell types from rats.
