Skin tissue regeneration and barrier function improvement effect of Panax PDRN in a 3D skin model. (A,B) Analysis of the skin regeneration ability in the 3D skin model using the wound-healing assay when treated with 5% or 50% Panax PDRN. (C) After treatment with Panax PDRN, the recovery of the damaged skin barrier was confirmed through TEER measurement and (D) immunostaining in the tissue. * p < 0.05 compared with basal levels. Red dash line: non epithelialized area; blue solid line: initial wound area.
