(A) Collagens were extracted from 5- and 8-week monolayer cultures grown in medium with or without 100 ng/mL of bone morphogenetic protein (BMP)-2. Two μg of total protein extracted was resolved on a 7.5% Tris-hydrochloric acid gel and western blotted for type I and type II collagen. (B) Immunohistochemical analysis for types I and II collagen in 5- and 8-week culture tissue from control and BMP-2–stimulated monolayer cultures. Specific labeling was developed using enzyme substrate vector red substrate kit. Images were taken at 10× magnification.
