April 1993 in “Cell” This study found that mice with a disrupted TGFα gene display a curly whisker-coat phenotype, similar to waved-1 mice, suggesting TGFα's crucial role in skin architecture and hair development.

,
May 1991 in “Genes & Development” This study observed that overexpression of TGF-alpha in transgenic mice led to thicker epidermis and stunted hair growth, particularly in regions with normally thick skin and low hair density.
October 2025 in “Clinical Cosmetic and Investigational Dermatology” This study synthesizes knowledge of how dendritic cell signals, epithelial integrins, and fibroblast activity converge on TGF-β1 to maintain or disrupt skin healing, contrasting normal and fibrotic scar formation and suggesting possible integrin and immune-targeted treatments for skin fibrosis.

October 2002 in “The FASEB journal” In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.
103 citations
,
July 2001 in “Proceedings of the National Academy of Sciences” This study found that conditional expression of TGFβ1 in mice affects epidermal and hair follicle growth, with chronic expression causing severe alopecia and a negative feedback loop involving Smad7.
