TLDR Neuregulin3 affects cell development in the skin and mammary glands.

The study demonstrated that Neuregulin3 (NRG3) significantly influenced cell fate in the epidermis and mammary gland by regulating epithelial proliferation and development. Using transgenic mouse models, researchers observed that NRG3 altered the expression and activation of ErbB receptors, leading to phenotypic changes such as hyperproliferation, sebaceous differentiation, and abnormal hair follicle structures. The findings suggested that NRG3 promoted epidermal proliferation and differentiation into sebaceous lineages over hair lineage, highlighting its potential as a target for therapeutic strategies in related disorders.
