This study demonstrated that engineered skin substitutes using human keratinocytes and murine dermal papilla cells can develop pigmented hairs without sebaceous glands, suggesting separate pathways for hair development and eruption.

This review discusses recent advances in hair regeneration strategies, including mechanical stimulation and complementary therapies like MSC transplantation and platelet-rich plasma, and reports no new clinical results.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This study found that a 671-base pair promoter sequence from the ultra-high-sulfur keratin gene is sufficient to direct tissue-specific and development-specific expression of a reporter gene during hair growth in transgenic mice.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.
