July 2012 in “Experimental Dermatology” In this study, treatment with human follicular keratinocyte-conditioned media improved the trichogenicity of cultured dermal cells by activating key signalling pathways, suggesting its potential use in cell therapy for hair loss.
November 2023 in “Cell Biology International” This study investigated the effects of exosomes from human umbilical cord mesenchymal stem cells on hair loss in mice with alopecia areata, emphasizing the potential of these easily isolated and stored exosomes for research and clinical treatment.
