MesenCult Osteogenic Diff Kit (Human)

Osteogenic differentiation of cultured human mesenchymal stromal cells (MSCs) into mineral-depositing osteoblasts is supported by a defined supplement system from STEMCELL Technologies. The MesenCult Osteogenic Differentiation Kit (Human) pairs a basal medium with a serum-free osteogenic supplement containing dexamethasone, ascorbic acid 2-phosphate, and beta-glycerophosphate, delivering the biochemical cues required for matrix mineralization across a 14 to 21 day in vitro differentiation timeline.

Bone tissue engineering laboratories, osteoporosis research groups, and musculoskeletal drug discovery teams rely on this kit to drive reproducible osteoblast differentiation from primary bone marrow- and adipose-derived MSCs. The standardized formulation reduces lot-to-lot variability compared with manually supplemented media, supporting consistent alkaline phosphatase activity, calcium quantification, and Alizarin Red S staining across donor sources. The complete differentiation kit is supplied with separate basal medium and concentrated supplement components; supplement components are stored frozen at -20 °C and aliquoted to limit freeze-thaw cycles.

A typical workflow begins with MSC expansion in compatible MesenCult proliferation medium, seeding at roughly 3 x 10^4 cells/cm^2, and a medium switch once cultures reach 70 to 80% confluency. Researchers replace the differentiation medium every 3 to 4 days. By day 21, cultures typically display von Kossa-positive mineralized nodules, elevated osteocalcin expression, and quantifiable calcium deposition, establishing the system as a reference platform for in vitro osteogenesis research.
