Figure 7. The closure of scratched HCEC wounds in response to 0.5% CMC, 0.3% HA and 0.1% HA stimulation.

The effect of CMC and HA on wound closure was visualized and also represented as the percentage reduction of the average wound width 24h after confluent HCECs were scratch wounded and incubated in the culture medium in the absence (A) or presence of CMC (B) or HA (C&D) (2 mg/mL). Data represent the mean±SD (n=3) of percentage reduction of the wound width which was measured as the average width of the 10 measurements along the wound edge. CMC and HA stimulation was significant compared with the control and CMC showed more wound healing effect than HA.
