This article corrects: In our original published version of Fong et al., J. Cell. Biochem (2014) 115: 290–302, the histology panel C of Figure had incorrect images. The correct Figure and its legend is published below with the histology panel C removed. The description of the histological features that were observed in the study remains the same in the body of the text. 3 (Figure presented.) A: Digital images of mouse excisional wounds showing faster wound closure by 14 days (D14) in SCID mice exposed to GFP-hWJSCs and hWJSC-CM (treatment arms) (white arrows) compared to controls (GFP-CCDs, CCD-CM, and UCM). B: On day 7, mean ± SEM percentage healing rates in excisional wounds in SCID mice were significantly greater in the treatment arms (GFP-hWJSCs and hWJSC-CM) compared to controls (*P < 0.05). On day 14, the mean ± SEM percentage healing rates were significantly greater for the GFP-hWJSCs treatment arm compared to controls (*P < 0.05).
