Figure 1. Expressions of BMPs and BMP receptors in human and guinea pig sclera. A: Semi-quantitative RT–PCR analysis of total RNA from 3 normal human sclera and 3 normal guinea pig sclera using specific primers for BMP-2 to BMP-7, BMPR-IA, BMPR-IB, and BMPR-II normalized to Actb at 35 cycles (M: molecular size marker). B: Distribution of the BMPs in human sclera by indirect immunofluorescence (FITC marked the secondary antibody).
