Cell attachment is a crucial step in tissue regeneration. In this study, human bone marrow stromal cells (hBMSCs) were isolated, and the effects of CCN2 on their attachment were examined. CCN2 significantly enhanced the hBMSC attachment, and this enhanced cell attachment was mainly regulated by the C-terminal module of CCN2. This enhancement was negated by the anti-integrin αvβ3 antibody and p38 MAPK inhibitor, and phosphorylation of p38 MAPK was detected upon the enhanced cell attachment mediated by CCN2. We thus conclude that CCN2 enhances hBMSC attachment via integrin-p38 MAPK signal pathway. Enhanced hBMSC attachment on hydroxyapatite plates by CCN2 further indicated the utility of CCN2 in bone regeneration.
