The study addressed the challenge of hair loss, particularly in large areas of alopecia where patients lack sufficient hair for auto-transplantation. Traditional 2D cultures for multiplying hair follicle stem cells (SCs) were unsuccessful, leading to the development of a 3D culture technology that successfully formed new hair follicles suitable for transplantation. The research also explored the use of Fetal Tissue Extracts (FTEs) to create a supportive microenvironment for SCs, showing high efficacy in treating liver cirrhosis and non-healing wounds in patients unresponsive to previous SC treatments. The combination of SC transplantation and SC-derived exosomes in a rejuvenation program yielded optimal therapeutic results in 78.9% of patients, significantly reducing biological age and frailty index, thus lowering the risk of age-related diseases. The findings highlighted the potential of 3D cultivation, in vivo modeling of SC niches, and prenatal SC exosomes to enhance the outcomes of SC-based regenerative medicine.
