Peroxisome proliferator-activated receptor-γ signalling protects hair follicle stem cells from chemotherapy-induced apoptosis and epithelial-mesenchymal transition.

Since a key cyclophosphamide metabolite alone suffices to damage and deplete human scalp eHFSCs by promoting apoptosis, DNA damage and EMT ex vivo, strategies to prevent pCIA need to target these pathomechanisms. Given the ability of NAGED to prevent chemotherapy-induced eHFSCs damage ex vivo, our study introduces the stimulation of PPAR-γ signalling as a novel intervention strategy for the prevention of pCIA.
