October 2005 in “Journal of Investigative Dermatology” This study found that human hair follicle stem cells formed more colonies and adhered more rapidly, while transit-amplifying cells showed significantly greater mobility.

September 2017 in “Cancer Research” This study reports that hair follicles can mobilize ectopic progenitors for regeneration to repair damage from ionizing radiation. Augmenting WNT signaling enhanced this regenerative process and prevented radiation- and chemotherapy-induced hair loss, highlighting a potential approach to manage alopecia during cancer treatment.

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.
In this study, various cellular responses and signaling pathways were examined in hair follicles after exposure to ionizing radiation, including the effects of Wnt3a treatment, with findings noted in apoptosis, DNA damage, and differentiation processes.
