Individual hydrogels releasing BMP-2 were exposed to fresh cultures every 3 days (consecutive treatment) for up to 27 days and ALP activities were determined (A). In a separate experiment, cells were cultured for up to 28 days (continuous treatment) in the presence of BMP-2 releasing hydrogels and ALP activities were determined (B).
