This study found that Sox10 may play a role in early hair follicle development and cycling, as it is expressed in specific regions of the hair follicle during different phases of the hair cycle in mice.

In this study, nestin-expressing cells in the hair follicle bulge, marked by GFP in transgenic mice, were identified as progenitors of the hair follicle outer-root sheath.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

This study reports the cloning and sequencing of two type II hair-specific keratin genes, ghHb1 and ghHb6, located on chromosome 12q13, which are expressed during hair growth.

This review explores the mechanisms of wound-induced hair follicle neogenesis in mice, discussing its potential to inform precision therapies for alopecia and scarless wound healing, but reports no new clinical results.

This study found that exposing adult esophageal epithelial cells to skin stroma can induce them to transition toward a hair follicle identity, with HIF1a playing a crucial role in this conversion process.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This study found that keratinocytes show increased expression of the TGF-β system and collagen type I with age, suggesting a heightened profibrotic response during skin differentiation associated with scarring.

This study identified genes potentially involved in the development and differentiation of skin appendages in Atelerix albiventris, noting significant enrichment of immune-related genes in hair-type tissues.

This study demonstrated that bioengineered hair follicles reconstituted from embryonic skin cells and transplanted into hosts can restore physiological hair functions, suggesting potential applications for treating alopecia.

This study identifies a specific cell population, PDGFRα+/Sca1+/CD34+ mesenchymal cells, which play a crucial role in regenerating hair follicles by promoting the downgrowth phase of the hair cycle, offering insights into organ morphogenesis and stem cell niches essential for adult hair regeneration.

This study identified two distinct fibroblast subsets in mouse skin, revealing that adult skin scarring occurs due to the repair process utilizing only one, lineage-restricted fibroblast type instead of coordinated diverse populations.

This study found that Brg1, a chromatin-remodeling enzyme, plays a critical role in hair regeneration and early epidermal repair by regulating bulge stem cells through a Brg1-Shh interaction.

This source reviews current understanding of fibroblast lineage differentiation and its role in wound healing, highlighting the potential to reprogram adult cells for scar-free repair by emulating fetal-like regenerative states.

This study found that in skin blister healing, hair follicle development is compromised as stem cells repair wounds at the expense of morphogenesis gene expression.

In this study using live mice, researchers observed that during hair follicle regression, apoptosis in basal cells may propagate by triggering neighboring cells, potentially regulated by a gradient of pro-survival signals from stem cells, and proposed a testable mechanism to further explore this process.

This review examines the complex mechanisms that regulate skin stem cell development, activation, and differentiation, emphasizing the molecular signaling pathways that influence their fate and contribute to skin homeostasis.

This study observed that the expression of EGF and EGFR increased during goat fetal skin development, suggesting these components play significant roles in skin maturation.
