This study found that Bone morphogenetic proteins (BMPs) play a crucial role in dermal papilla cells' ability to induce hair follicle stem cell differentiation, and that androgens may impair this process by downregulating BMPs.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This study found that while Eda and Edar proteins interact in vitro, their roles in dental development differ, with downless mutant mice showing distinct tooth defects compared to tabby mutants.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This study reports that overexpression of activin in transgenic mice enhances granulation tissue formation during wound healing, highlighting a novel role for activin in cutaneous repair processes.

This study suggests that a novel micropatterned dermal–epidermal matrix (μDERM) enhances keratinocyte function and epidermal morphology, offering potential improvements in skin substitute design for wound healing applications.

This study demonstrated that an engineered human skin equivalent can generate follicle-like structures resembling fetal skin, highlighting the role of the dermal compartment in directing epithelial cell fate in vitro.

This study found that TSC2-null fibroblast cells from TSC skin hamartomas can induce hair follicle formation and hamartomatous changes in keratinocytes, with active mTOR signaling observable in a mouse xenograft model.

This study found that knocking out the transactivation domain of Miz1 in mouse keratinocytes disrupted hair follicle orientation, caused irregular pigmentation, and increased keratinocyte proliferation, indicating Miz1's role in hair follicle development and morphogenesis.
