Abstract (original English)
Nowadays, discovering osteogenesis stimulating effectors is one of the major topics in bone tissue engineering and regenerative medicine. In this study, the proliferation rate and osteogenic differentiation potency of adipose-derived mesenchymal stem cells (AT-MSCs) cultured on poly (l-lactide acid) (PLLA) and willemite-coated PLLA were investigated by MTT assay and common osteogenic markers such as alkaline phosphatase (ALP) activity, calcium mineral deposition and bone-related genes expression. Willemite-coated PLLA showed a higher proliferation support to AT-MSCs in comparison to PLLA and TCPS. During the period of study, AT-MSCs cultured on willemite-coated PLLA scaffolds exhibited the greatest ALP activity and mineralization. Gene expression analysis demonstrated that the highest expression of four important osteogenic-related genes, osteonectin, Runx2, collagen type 1 and osteocalcin was observed in stem cells cultured on willemite-coated PLLA nanofibrous scaffolds. According to the results, willemite-coated PLLA could be a suitable substrate to support the proliferation and osteogenic differentiation of stem cells and holds promising potential for bone tissue engineering and regenerative medicine applications.
