Studysummary This study found that doxorubicin disrupts hair-follicle-associated blood vessels, which may contribute to hair follicle dystrophy and alopecia in mice, but hair-follicle stem cells remained unaffected.

The study found that the chemotherapy drug doxorubicin disrupted the blood vessel network associated with hair follicles in ND-GFP transgenic mice, leading to reduced vessel density and dystrophic hair follicles, which contributed to chemotherapy-induced alopecia. However, it did not affect hair-follicle stem cells, allowing for potential hair regrowth after chemotherapy. The research highlighted the role of inhibited angiogenesis in hair follicle dystrophy and alopecia, providing a model for studying the effects of chemotherapy on hair follicles and tumors.
