From: Comparative analysis of the effects of opioids in angiogenesis
The effects of opioids in HUVEC apoptosis. Morphine, fentanyl and oxycodone but not codeine at 0.1 μM to 1000 μM decreased apoptosis. VEGF at 15 ng/ml was used. Results shown are relative to control. Each experiment was repeated three times in triplicate, and each value indicates mean ± SD. *p < 0.05, compared to control
