November 2022 in “Journal of Investigative Dermatology” This study found that "early" transit amplifying cells, marked by CD271, are the first keratinocyte stem cell progenitors with distinct features, playing a significant role in early epidermal differentiation and regeneration.
November 2022 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that conditional deletion of CD271 in mouse epidermis led to significant disorganization and increased thickness, suggesting CD271's crucial role in regulating skin differentiation and structure.
October 2025 in “Cell Death and Disease” In this study, researchers developed two novel mouse models to investigate how CD271 deletion in keratinocytes affects skin homeostasis, finding that it leads to changes resembling dysplastic skin conditions with immune cell recruitment and inflammatory cytokine release.
November 2022 in “Journal of Investigative Dermatology” This study found that stimulating the olfactory receptor OR2A4/7 with cyclohexyl salicylate promoted human hair growth and increased progeny of hair follicle epithelial stem cells in an ex vivo setting.
July 2022 in “Journal of Investigative Dermatology” This study found that the cosmetic olfactory receptor agonist cyclohexyl salicylate may stimulate hair growth and expand stem cell progeny, suggesting potential as a cosmetic adjuvant for hair loss.
