The schematic presentation of the perinatal derivatives used in skin wound healing in preclinical studies. Cells: hUC-MSC, human umbilical cord mesenchymal stromal cells; hAMSC, human amniotic membrane mesenchymal stromal cells; hPMSC, human placenta mesenchymal stromal cells; hUC-PVC, human umbilical cord perivascular cells; hAEC, human amniotic membrane epithelial cells; hAFSC, human amniotic fluid stem cells; hAFC, human amniotic fluid cells; Conditioned media (CM) derived from hUC-MSC, hAEC, hAMSC, hPMSC, hUC-PVC; Small extracellular vesicles (sEV) derived from hUC-MSC, hAMSC, hDMSC; Tissues: hAM, human amniotic membrane; hAM/hCM, human amniotic/chorionic membrane; Tissue extracts derived from hAM, hP (human placenta), hP-ECM (human placenta-derived extracellular matrix), hWJ-ECM (human Wharton’s jelly derived extracellular matrix).
