Fig. 2From: Changes in phenotype and differentiation potential of human mesenchymal stem cells aging in vitroMorphological representation of in-vitro aging MSCs. Phase-contrast images of MSCs at P3 through P8 exposed to the DMEM-based (top panel) and αMEM-based (bottom panel) culture conditions were captured on days 4, 7, and 10. Scale bars = 100 μm. αMEM, minimum essential medium alpha; DMEM, Dulbecco’s modified Eagle’s mediumBack to article page
