Example application: osteogenic differentiation of mesenchymal stem cells
Objective
Perform a CombiCult™ screen to identify new and improved serum-free protocols for differentiation of primary
human mesenchymal stem cell (MSCs) to osteochondral lineages.

Screen
A CombiCult™ screen comprising 15 serum-free media in 3,375 (153) combinations.
![]()
Results
Validation and refinement of serum-free differentiation protocols determined by CombiCult™ resulted in identification of protocols that drive rapid MSC differentiation to mineralizing osteocytes.
The novel protocols are more effective than commercially available media formulations, most of which contain serum, and give consistent results across multiple cell lines.
Aizarin red staining of MSC cultures differentiated for 28 days; cell lines 1-3: bone marrow-derived MSC, cell line 4: adipose-derivied MSC.
