Autocrine and Paracrine Effects of Vascular Endothelial Cells Promote Cutaneous Wound Healing

Figure 1

Flow diagram: the supernatant of P3 umbilical vein endothelial cells was collected, filtered, and concentrated tenfold using vacuum freeze-drying centrifugation. One part was mixed with several factors that participate in wound repair, and the other part was used to treat full-thickness skin defects in mice.
