research The Expression Rules of Wnt10b and SFRP2 Genes in the Skin of Wanxi Angora Rabbits January 2013 Wnt10b promotes hair growth, while SFRP2 inhibits it in Wanxi Angora rabbits.
research Mouse Hair Cycle Expression Dynamics Modeled as Coupled Mesenchymal and Epithelial Oscillators 12 citations, November 2014 in “PLOS Computational Biology” The study concluded that hair growth in mice is regulated by a stable interaction between skin cell types, and disrupting this can cause hair loss.
