Epithelial cell differentiation of human mesenchymal stromal cells in decellularized lung scaffolds.

ABSTRACT: Identification of appropriate donor cell types is important for lung cell therapy and for lung regeneration. Previous studies have indicated that mesenchymal stromal cells derived from human bone marrow (hBM-MSCs) and from human adipose tissue (hAT-MSCs) may have the ability to trans-differentiate into lung epithelial cells. However, these data remain controversial. Herein, the ability of hBM-MSCs and hAT-MSCs to repopulate acellular rodent lung tissue was evaluated. hBM-MSCs and hAT-MSCs were isolated from bone marrow aspirate and lipoaspirate, respectively. Rat lungs were decellularized with CHAPS detergent, followed by seeding the matrix with hBM-MSCs and hAT-MSCs. Under appropriate culture conditions, both human MSC populations attached to and proliferated within the lung tissue scaffo
