This study reports that follicular cells isolated from murine skin can regenerate hair follicles after being injected into nude mouse skin, with the regeneration process relying on cell interactions, recipient sites, and cell numbers.

This study explored the structure and keratin composition of marsupial hairs, finding similarities in keratin localization to hairs in placental mammals, and highlighting potential roles of trichohyalin and transglutaminase during hair development and shedding.

This study describes a protocol for generating a fully functional 3D integumentary organ system from murine induced pluripotent stem cells, including the formation of hair follicles and sebaceous glands that function in vivo.

In this case report, researchers observed multiple trichofolliculomas in family members, noting this as a rare manifestation of typically singular hair follicle hamartomas.

This study found that deleting FoxN1 in specific thymic epithelial cells disrupted the 3D thymic structure and led to age-dependent formation of 2D epithelial cysts, highlighting FoxN1's critical role in thymic morphogenesis.

This research suggests that defects in keratinocyte differentiation due to putrescine accumulation in SSAT transgenic mice lead to skin changes and hair loss, and reducing putrescine can promote hair regrowth.

This study re-examined the structure of lanceolate endings in rat vibrissae, suggesting that their apical cones may function as a transducer site for detecting hair movements.

This study found that human hair follicle bulge stem cells exhibited autofluorescence, potentially due to high flavin- and NAD-related compound levels, highlighting the need to consider this when using fluorescent antibodies for studying these cells.

This review discusses recent advancements in generating appendage-bearing skin organoids from pluripotent stem cells and their potential applications in dermatological research, but reports no new clinical results.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

Stem cells in mouse nails are found in the nail matrix and may control nail growth.

This study observed that Langerhans cells and melanocytes migrated to hair follicle sites during human embryogenesis, suggesting that Langerhans cells acquire immunoregulatory properties there.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

In this study, Hedgehog signaling in dermal papilla fibroblasts was found to accelerate hair growth and induce follicle multiplication in mice via the SCUBE3/TGF-β pathway, with some effects observed in human scalp hair follicles.

This study found that PGRP-S expression in mouse epidermis is specific to certain hair follicle epithelia, depending on the skin region, and can be transiently induced in flank skin hair follicle epithelium after exposure to Staphylococcus aureus, suggesting a role in environmental surveillance.

This study developed 3DEEP, a tissue clearing and spatial transcriptomic method, to map hair follicle development in a single time point from a 12-hour-old mouse, detailing molecular stages, signaling dynamics, and structural changes within developing follicles.

This study found that the gene BSSP, a serine protease, is predominantly expressed in sebaceous glands and is overexpressed in nude mouse skin.

This study proposed the existence of a membrane-like structure between the cuticle and cortex in human hair, which may provide strong protection against external stimuli.

This study identified two new Wnt genes, EsWnt1 and EsWnt4, in red starfish, with their expression patterns suggesting a role in wound healing and regeneration.

This study observed that key signaling events controlling hair growth in ferret follicles occur between 0 and 4 days after melatonin implantation, highlighting distinct processes in follicular regeneration and fibre growth.

In this study, the researchers observed that the expression of certain growth factors and their receptors increases with gestational age, implying a role in skin development, structure maintenance, and wound healing.

This study found that hair follicle-specific keratins can form different structural assemblies depending on ionic conditions, with hair cortex keratins requiring physiological salt conditions to form intermediate filaments.

This study reported that exogenous R-spondin-1 can restore hair follicle neogenesis in adult mouse cells, highlighting differences in gene expression and signaling pathways between fetal and adult dermal papilla cells.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This article reports on lentiginosis observed within plaques of linear atrophoderma of Moulin and discusses its potential classification as a twin-spotting phenomenon but provides no new clinical research results.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

In this study, the researchers found that EGF and EGFR play crucial roles in goat fetal skin development, with their expression increasing progressively during gestation.

In this study, researchers observed that different ERK signal activation dynamics during hair follicle regeneration are linked to cell fate specification and are affected by distinct upstream signaling pathways.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.
