This study found that Polyomavirus A2 infection in mice led to the development of pilomatricomas in hair follicles, with the virus replicating initially in the skin and later infecting matrix cells.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This study found that combined loss of Atr and p53 in adult mice led to severe tissue degeneration and delayed regeneration due to the accumulation of highly damaged cells.

This study found that prolactin plays a direct role in regulating the timing of hair growth cycles in mice by affecting the skin, rather than through other endocrine factors.

This study found that the vitamin D receptor is essential for the self-renewal, migration, and differentiation of epidermal stem cells during skin wound healing in mice.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

In this mouse study, researchers found that hydrogen peroxide and monoethanolamine in hair dyes may be key contributors to dermatitis and hair loss due to oxidative stress.

This study found that reducing HDAC1 activity in the skin of mice led to defects in hair follicle structure and pigmentation, highlighting HDAC's role in skin and hair maintenance.

This review of stem cell-based tissue engineering treatments in preclinical burn wound models reports promising improvements in skin repair, suggesting potential as an enhanced therapy for burn wounds.

In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.

This study found that the loss of Smad4 in keratinocytes reduces Dsg4 expression via disrupted BMP signaling, contributing to hair follicle degeneration and alopecia.

This study identified a large deletion in the desmoglein 4 gene as the genetic basis of the Iffa Credo "hairless" rat's skin phenotype, linking it to lanceolate hair mutations.

This study reported that heterozygosity for FHIT affects mice's susceptibility to spontaneous alopecia areata and to certain preneoplastic lesions induced by benzo[a]pyrene, but does not change how they respond to budesonide and N-acetyl-L-cysteine.

This study found that HPV16 oncogene expression in multipotent epithelial stem cells led to abnormal mobilization, altering their quiescence without affecting other stem cell markers, suggesting a distinct stem cell compartment.

This article reviews the interaction between sex hormone pathways and morphogenesis-related signaling in epithelial organ development, using a chicken model to propose testable hypotheses, but reports no new clinical results.

This study found that exposure to finasteride impaired spermatogenesis in male Xenopus laevis by affecting sex-specific feedback mechanisms in the hypothalamus–pituitary–gonad axis.

This study found that hairless mice with homozygous mutations developed significantly more aggressive basal cell carcinomas and a heightened inflammatory response to UVB exposure compared to their haired littermates.

This study suggests that the patchy thickening and reddish discoloration in rabbit skin during the hair cycle may be due to large anagen-phase hair follicles compressing the dermis and increased blood vessels causing redness.

This study found that the penta-peptide Gly-Pro-Ile-Gly-Ser increased the proportion of thick hair and improved baldness appearance in Japanese men with androgenetic alopecia.

This study found that Fraser's Dolphin, a tight-skinned mammal, can regenerate complex skin architecture with minimal scarring after large full-thickness wounds, even in high-tension environments, offering insights into regenerative healing mechanisms typically obscured by fibrotic responses.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

This study indicates that the Sp6 gene is crucial for the development of skin, teeth, limbs, and lungs in mice, possibly through regulating apoptosis.

This study developed a multifunctional bilayer dressing containing nanosilver and basic fibroblast growth factor, which improved wound healing by preventing bacterial penetration, promoting angiogenesis and hemostasis, and accelerating cell proliferation and migration, outperforming a control group by increasing healing rates by 47% in vivo.

This study found that ATP synthases and the mitochondrial gene COX2 play a key role in determining the size of skin appendages in hedgehogs and mice by influencing energy metabolism and cell proliferation.

In this study, researchers observed that dormant TRP-2+ melanoma cells in bone marrow can interact with CD8+ T cells in tumor-bearing ret transgenic mice, potentially influencing immune responses.

In this study, sildenafil was found to enhance human dermal papilla cell proliferation and promote hair growth in mice, suggesting potential use in alopecia treatment.

This study found that experimentally induced hypothyroidism in rats is associated with impaired skin structure, but topical application of triiodothyronine (T3) improved these changes to resemble normal skin.

This review evaluates existing research on topical metformin for skin conditions, reporting promising outcomes such as improved wound healing, melasma, psoriasis, acne, and alopecia, with innovative formulations like hydrogels and lipid nanoparticles enhancing its cutaneous delivery while minimizing systemic exposure.
