IN VITRO EVALUATION OF SURFACE STIFFNESS EFFECTS ON OA-PATIENTS' MSC OSTEOGENIC LINEAGE COMMITMENT

British Orthopaedic Research Society (BORS) Annual Conference



Abstract

hMSC cultures were prepared from osteoarthritic patients. Silicone elastomer (PDMS) culture surfaces of varying degrees of stiffness (1:10, 1:30 and 1:50 PDMS, tissue culture plastic and glass) were investigated in isolation and in combination with differentiation media. CD marker expressions of ‘stemness’ were investigated. RNA expression changes in OA-hMSCs and non-OA-hMSCs were also investigated for a panel of genes (inclusive of ‘stemness-’ and osteogenic-linked genes, FKBP5 and osteomodulin).
