Direct reprogramming of human fibroblasts into sweat gland-like cells.

ABSTRACT: The skin of patients with an extensive deep burn injury is repaired by a process that leaves a hypertrophic scar without sweat glands and therefore loses the function of perspiration. The aim of this study was to identify whether the key factors related to sweat gland development could directly reprogram fibroblasts into sweat gland-like cells. After introducing the NF-κB and Lef-1 genes into fibroblasts, we found that stably transfected fibroblasts expressed specific markers of sweat glands, including CEA, CK7, CK14 and CK19, both at the protein and mRNA levels. The immunofluorescence staining also showed positive expression of CEA, CK7, CK14 and CK19 in induced fibroblasts, but there were no positive cells in the control groups. The expression of Shh and Cyclin D1, downstream genes of NF
