Stem cell therapy has shown promise in treating a variety of pathologies including skin wounds, but practical applications remain elusive. Here, we demonstrate that endogenous stem mobilization produced by AMD3100 and low-dose tacrolimus is able to reduce 25% the time complete healing full-thickness wounds created surgical excision. Equally important, was accompanied reduced scar formation regeneration hair follicles. Searching for mechanisms, found combined with mobilized increased number...
