July 2017 in “Wiley Interdisciplinary Reviews-Developmental Biology” This review discusses the emerging roles of transit-amplifying cells in tissue regeneration and cancer formation, highlighting their significance beyond a mere transitional state in hair follicles and the hematopoietic system.
April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that local PGE2 injection may prevent radiotherapy-induced hair loss by protecting hair follicle cells and promoting hair follicle self-repair.
This research reports that after genotoxic stress from ionizing radiation or chemotherapy, hair follicles can utilize progenitor cells from transit-amplifying compartments, not quiescent stem cells, for repair, suggesting a potential therapeutic approach to prevent therapy-induced hair loss by activating these progenitors.
