This study aims to investigate the effects of dexamethasone on apoptosis in human mesenchymal stem cells (MSCs) related to cell density.
Analyzed apoptosis via DAPI staining and DNA fragmentation ELISA Assay in MSC cultures initiated at different cell densities.
Co-cultured MSCs and fibroblasts to assess the role of soluble factors in density-related apoptosis.
Compared apoptosis levels in BrdU-labeled MSCs cultured alone and with unlabeled chondrocytes at varying densities, with and without dexamethasone.
Higher MSC density correlated with increased apoptosis, especially in cultures without dexamethasone.
Apoptosis was significantly reduced in cultures containing 100 nM dexamethasone, indicating protective effects.
Direct cell contact was necessary for the observed density-related apoptosis.
