Visualization of calcium mineralization (black deposits) using von Kossa staining after hASC/hTERT microspheroid encapsulation in 5%, 7.5%, or 10% Gel-MOD hydrogels and a 3-week differentiation in osteogenic medium. Green arrows indicate stronger mineralization in close proximity to the encapsulated microspheroids. Scale bars = 100 μm. Color images are available online.
