VEGF, an important growth factor to drive angiogenesis, was higher in response to the synergism between hyaluronic acid (10%) and green tea (10%) in human fibroblasts. Control cultures were considered when the cells were maintained under classical conditions, without any treatment. The value of expression was normalized with 18S data (housekeeping gene).
