July 2022 in “Journal of Investigative Dermatology” This study found that Dkk4-knockout mice exhibited disrupted hair follicle patterning, including a lack of the first wave of hair follicles in the lateral back skin.
October 2021 in “Journal of Investigative Dermatology” This study reported that Dkk4-knockout mice showed disrupted hair follicle patterning, suggesting a WNT-DKK axis may influence regional specificities in hair follicle induction related to androgenetic alopecia.

February 2012 in “Developmental biology” This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.
November 2022 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, researchers mapped gene expression in developing hair follicles to reveal unknown cell populations and markers, suggesting early establishment of cell fates in hair placodes.
