Exosomes for Hair Growth and Regeneration
November 2023
in “Journal of Bioscience and Bioengineering”
TLDR Exosomes show promise for hair growth but face challenges in standardization and concentration for clinical use.
Exosomes, a type of extracellular vesicle, have been studied for their potential in promoting hair growth and regeneration due to their long shelf life, simple storage conditions, long intracellular communication distances, and low risk of immune responses. These characteristics make them superior to direct cell therapy. Exosomes derived from dermal papilla cells (DPCs), which are mesenchymal cells with adult stem cell properties that regulate hair follicle development, are widely used in hair studies. In one study, human two-dimensional cultured DPC-derived exosomes were injected into the dorsal skin of mice, resulting in hair follicle growth. However, there are limitations to the clinical application of exosomes, including a lack of uniform standards for origin, isolation, purification, identification, and storage, and the need for precise quantification and effective concentration methods.
