Improving the effectiveness of adipose-derived human mesenchymal stromal/stem cells (AMSCs) for skeletal therapies requires a detailed molecular characterization of mechanisms supporting cell proliferation and multi-potency of AMSCs. We compared gene expression data obtained by high-throughput RNA sequencing and RT-qPCR of actively proliferating and uninduced post-proliferative AMSCs with flow cytometry data for mesenchymal stem cell markers (e.g., CD44, CD73/NT5E, CD90/THY1 a...

Few drugs generate bone-stimulatory effects via epigenetic mechanisms. Modulation of CpG-residues hydroxymethylation in gene-promoters of key osteoblast-related factors (e.g., DLX5) induces their expression and increases osteoblast differentiation in vitro. The chemical properties of sulforaphane (SFN), a natural compound abundantly present in cruciferous vegetables like broccoli, suggest that it may have similar molecular and biological effects.
