Substance P enhances EPC mobilization for accelerated wound healing

Wound healing is essential for the survival and tissue homeostasis of unicellular and multicellular organisms. The current study demonstrated that the neuropeptide substance P (SP) accelerated the wound healing process, particularly in the skin. Subcutaneous treatment of SP accelerated wound closing, increased the population of α-smooth muscle actin positive myofibroblasts, and increased extracellular matrix deposition at the wound site....
