December 2009 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” This study found that in keratin 14-targeted transgenic mice, BMP antagonism via noggin led to the development of hair follicle tumors, mediated through alterations in Wnt and Shh signaling pathways.
This study demonstrated that a ligand-independent action of the vitamin D receptor significantly affects keratinocyte behavior in hair follicles and skin, pointing to its crucial role in maintaining normal hair and skin structures in rats.
April 2016 in “Journal of Investigative Dermatology” This study found that Sonic hedgehog signaling is crucial for Merkel cell development around hair follicles in mice, with Polycomb repressive complex 2 loss causing ectopic Merkel cells across all hair types.
This study suggests that Sonic hedgehog from hair follicles may support the proliferation of dentate neural stem cells in mice through transport by platelets during the perinatal period.

June 2012 in “Genes & Development” This study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.
