PURPOSE. To characterize the cellular expression patterns of antiangiogenic factorsdifferentially regulated in the fetal human macula. METHODS. RNA was extracted from macular, nasal, and surround biopsies of three human fetal retinas at midgestation. Relative levels of expression of pigment epithelium- derived factor (PEDF), brain natriuretic peptide (BNP), collagen type IV_2 (COL4A2), and natriuretic peptide receptors A and C (NPRA and NPRC) were determined with quantitative PCR.
