β1 integrin regulates in vitro mineralization in an Icap-1–dependent manner. β1fl/fl (wild type), β1WT (rescue), β1D759A, β1V787T, and β1−/− cells were induced to differentiate into osteoblasts. Expression of alkaline phosphatase (ALP) was used to follow the early commitment of cells to the osteoblast lineage at day 0 (D0) and day 15 (D15). Mineralization was visualized by Alizarin red S staining (ARS) at day 20 (D20). Arrowheads indicate mineralized bone nodules. Bar, 1 mm.
