From: β3-integrin is required for differentiation in OC-2 cells derived from mammalian embryonic inner ear
β1 and β3-integrin expression profiles change during differentiation. Surface expression of (A) β1-integrin and (B) β3-integrin was examined by FACS at days 2, 6, 10 and 14 of the differentiation process The differentiating cells ('dif' red line) were compared to undifferentiated ('33' green line) and fully differentiated cells ('39' red line). Increase of β1-integrin expression profile is visible from day 2 and it reaches the level of differentiated cells by day 10. β3-integrin expression which is undetectable above the Ig signal up to day 2, becomes visible at day 6 and gradually reaches the differentiated levels at day 14.
