Abstract (original English)
The human amniotic membrane (hAM) has been applied as a scaffold in tissue engineering to sustain stem cells and enhance their regenerative capacities. We investigated the molecular and biochemical regulations of mesenchymal stromal cells (MSCs) cultured on hAM scaffold in a three-dimensional (3D) setting. Culture of adipose-MSCs (AMSCs) on decellularized hAM showed significant improvement in their viability, proliferative capacity, resistance to apoptosis, and enhanced MSC markers expression. These cultured MSCs displayed altered expression of markers associated with pro-angiogenesis and inflammation and demonstrated increased potential for differentiation into adipogenic and osteogenic lineages. The hAM scaffold modulated cellular respiration by upregulating glycolysis in MSCs as evidenced by increased glucose consumption, cellular pyruvate and lactate production, and upregulation of glycolysis markers. These metabolic changes modulated mitochondrial oxidative phosphorylation (OXPHOS) and altered the production of reactive oxygen species (ROS), expression of OXPHOS markers, and total antioxidant capacity. They also significantly boosted the urea cycle and altered the mitochondrial ultrastructure. Similar findings were observed in bone marrow-derived MSCs (BMSCs). Live cell imaging of BMSCs cultured in the same 3D environment revealed dynamic changes in cellular activity and i
