Effect of Zn2+ or Se2+ added papaya extracts on expression of TGF-β1 and VEGF A at the wound area. A marked increase in TGF-β1 expression in the wound area was observed only at day 4 (row 1) unlike at day 10 (row 2) after treatment with PC, PE and PES as compared to the NC and PEZ. A marked increase in VEGFA expression was observed in the wound area at day 4 (row 3) after treatment with either PC, PE or PES. Expression of VEGFA was similar in the wound at day 10 (row 4) for all treatment groups (i.e., PE, PES, PEZ and NC). [n = 5 per group; Scale bar = 5 μm]
