Royal jelly (RJ) is exclusive food that is secreted from the hypopharyngeal and mandibular glands of worker honeybees, and it is well known to be a necessary for the growth of the queen honeybee Although fresh royal jelly have been demonstrated to enhance wound healing, the wound healing effects of water soluble royal jelly (WSRJ) have not been elucidated. We investigated whether WSRJ promotes the migration, attachment, and proliferation of human dermal fibroblasts (HDFs) during in vitro wound healing. HDFs were treated with 1-5ug/ml WSRJ and RJ for up to 24hr following wound formation. Cell migration was assessed by measuring recovery from wound margin, while cell attachment and proliferation were determined by MTT assay. By observing the numbers of cell attached, we confirmed that not only WSRJ but also RJ did not affect on the initial cell adhesion. WSRJ (5 ug/ml) enhanced cell migration rate approximately 84.3% in HDFs at 24hr, whereas RJ (5 ug/ml) increased cell migration rate 71.3% in HDFs at 24hr, which is similar to cell migration rate of WSRJ 1 ug/ml (73.7%). In cell proliferation assays, WSRJ induced an increase in the number of HDFs, compared with control and RJ. In conclusion, WSRJ promotes cell migration with increased cell proliferation in an in vitro wound healing model.
