This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

This study observed that chemically-induced intersex frogs displayed altered brain mRNA profiles, with finasteride increasing certain hormone-related gene expressions and fadrozole reducing aromatase activity without affecting gene transcript levels.

In this study, researchers found that TSPyV T antigens can disrupt normal cell differentiation and proliferation in hair follicles and interfollicular epidermis, possibly contributing to trichodysplasia spinulosa pathology.

This study found that Hex gene expression patterns in chick embryo dorsal skin during feather bud development suggest a significant role in initiating feather morphogenesis.

In this study, the RADA-PRG hydrogel enhanced SKP proliferation, survival, and gene expression, effectively supporting hair follicle regeneration in mice.

This study suggests that mouse lineage specification during pre-implantation development involves distinct timing and mechanisms for trophectoderm and inner cell mass differentiation, challenging existing models.

In this study, murine follicular cell aggregates developed into hair-like structures in culture, which upon implantation into mice skin matured into complete hair follicles, suggesting potential for treating hair loss.

This study demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.

This study presents the first detailed 3D models of the complete K1/K10 keratin dimer and identifies structural features and interactions that may inform understanding of keratin filament assembly.

This study demonstrated that fibrin hydrogels support skin-derived precursors in hair follicle neogenesis in mice, with new hair growth and regeneration of blood vessels and sebaceous glands observed.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

Secreted inhibitors of Wnt and IGF signaling control hair and tooth development, creating species-specific patterns.

This study suggests that spiny keratoderma may be an ectopic hair formation on palms and soles, based on keratinization patterns observed using antikeratin antibodies and electron microscopy.

This study reports that expressed mouse type Ia and type IIa trichocyte keratins were successfully assembled into intermediate filaments in vitro, while also suggesting that disulfide bond cross linking enhances their stability.

This study found that ribbed hairs on tarantulas closely resemble chemoreceptors rather than silk-producing spigots, with no silk observed emitting from them under microscopy.

In this case report, researchers described a unique skin lesion in a 55-year-old woman, identifying it as folliculosebaceous cystic hamartoma with an unusual combination of spindle cell lipomatous and neural components, which had not been previously documented in such cases.

Syringomas likely start in the upper dermis and form distinct luminal structures.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This review highlighted that in an in vitro setting, 3D spheroid cultures of fish cells offer a promising alternative to traditional monolayer cultures, potentially advancing research in eco-toxicology, immunology, drug screening, and more by better mimicking in vivo conditions.

This study found that transplanting cell aggregates from mouse skin and lung mesenchymal cells can regenerate hair follicles in immunodeficient mice with skin wounds.

This case report describes a rare pedunculated follicular hamartoma on the nasal septum of a 77-year-old Japanese male, emphasizing its unique clinical and pathological features.

In this study, researchers identified a temperature-sensitive mutation in the FERONIA gene of plants that prevents root hair formation at elevated temperatures, highlighting its role in maintaining root hair growth and response to plant hormones.

This study revealed that basement membrane dynamics are crucial to hair follicle development, influencing progenitor cell behavior and cell division patterns in developing mouse hair follicles.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

In this study, researchers discussed how specific protein interactions in reptile skin allow for the development of protective structures like scales and scutes, which facilitated reptiles' adaptation to terrestrial environments.

This study used developing mouse hair follicles to explore early epithelial bud formation, finding that the Rho GTPase regulator ARHGEF3 plays a crucial role in regulating cell fate and cadherin patterning, with knockouts showing disrupted morphology and increased straight hair follicle growth.

This study outlines a method to isolate hair follicle stem cells from mouse skin using fluorescence activated cell-sorting for use in research models, but reports no experimental findings.

This case report documents the first known instance of FOXN1 duplication linked to congenital hypertrichosis.
