Decellularized ECM effects on human mesenchymal stem cell stemness and differentiation.

ABSTRACT: Microenvironment extracellular matrices (ECMs) influence cell adhesion, proliferation and differentiation. The ECMs of different microenvironments have distinctive compositions and architectures. This investigation addresses effects ECMs deposited by a variety of cell types and decellularized with a cold-EDTA protocol have on multipotent human mesenchymal stromal/stem cell (hMSC) behavior and differentiation. The cold-EDTA protocol removes intact cells from ECM, with minimal ECM damage and contamination. The decellularized ECMs deposited by cultured hMSCs, osteogenic hMSCs, and two smooth muscle cell (SMC) lines were tested for distinctive effects on the behavior and differentiation of early passage ('naïve') hMSC plated and cultured on the decellularized ECMs. Uninduced hMSC decellularize
