Alizarin staining for the synthesis of bone mineral at 7, 14, and 21 days. The calcium minerals are stained in red. The mineral concentration was measured by osteogenesis assay and the results are shown in (d). The mineral concentration at day 21 is 10-fold higher than day 7, which demonstrated cells released from microbeads synthesized bone mineral successfully [53].
