Apelin reduces PDGF-stimulated PSC density

PDGF + Vehicle	PDGF + Apelin
127 ± 12	103 ± 7*

Values (means ± SE) are %increase in PSC density compared with PSCs not treated with PDGF; n = 7 wells per group. Cultures of mouse PSCs were exposed to PDGF-BB (10⁻⁸ M) + vehicle or apelin-13 (10⁻⁶ M) for 2 days.

^*P < 0.05 vs. PDGF + vehicle.
