Colon epithelial cell wound healing with nitrite. (A) SW480 colon epithelial cells were treated with varying concentrations of sodium nitrite (1 µM–1 mM), and (B) with or without cPTIO (100 µM) after wound incision. Healing was measured after 24 h and expressed as healing vs. 0 h (%) (P<0.01, ⁎ vs. untreated, # vs. Nitrite 100 µM).
