(A) Human mesenchymal stem cells (MSCs) and (B) MSCs cultured in osteogenic media (MSC-OM) were incubated with different PMMA bone cements for different time periods. Data are normalized to day 1 of controls and presented as mean ± SEM of five individual experiments (*p≤0.05, ***p≤0.001 vs. 1d-control w/o testing material).
