Research Abstract |
In mammals, type of skin wound healing drastically change in the middle stage of fetus, from fetal-type regeneration into adult-type scarring, but underlying mechanism is yet to be elucidated. Here we focused on angiogenesis and lymphangiogenesis during wound healing process, using fetal skin wound healing model. Before embryonic day 15, there were seldom vessels and lymphatic vessels forming tube-like structures. We also found that the macrophages before embryonic day 15 were larger in size compared to the ones in later stage, and the proportion of cells expressing LYVE-1 was higher in earlier stage. These results suggest that they have some unique ability in skin wound healing and contribute to skin regeneration.
