This study describes a method for labeling and tracking hair follicle stem cells in mouse skin using a Cre/lox recombination system with tamoxifen, providing insights into stem cell behavior and contribution to tissue regeneration.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This review discusses the roles and mechanisms of chromatin remodelers and their subunits in mammalian development, but reports no new experimental results.

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 found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.

This study found that hair-type tissues in hedgehogs show higher enrichment of immune-related genes compared to spine-type tissues, suggesting that spines evolved to protect against injuries and infections.

This study achieved regeneration of hair follicle-like structures and erector muscle of hair in vitro by simulating cellular organization and applying mechanical stimuli.

This review highlights the regenerative abilities of *Xenopus laevis*, focusing on how tadpoles regrow complex tail structures and the cellular and molecular mechanisms behind this. It underscores *X. laevis* as a valuable model for understanding regeneration, with insights potentially advancing regenerative medicine.

This study found that mouse embryoid bodies adhered quickly and differentiated efficiently into cardiomyocytes on negatively charged poly(sodium p-styrene sulfonate) hydrogels, similar to their behavior on gelatin-coated polystyrene.

Researchers created long-lasting, diverse skin organoids from mouse hair follicle stem cells, useful for studying skin.

This study found that generating pluripotent stem cell-derived skin organoids in a 3D bioprinted hydrogel device improved keratinocyte differentiation and hair follicle formation while reducing necrosis.

This research explored methods to obtain transgenic sheep embryos expressing synthetic spider silk genes in hair follicles using somatic cell nuclear transfer, with successful in-vitro development observed.

In this study, researchers used quantitative fate mapping to investigate how the infundibulum, part of the epidermis, is maintained during adulthood, finding that progenitors maintain this tissue through stochastic cell fate choices, with cells at the bottom providing transient support during hair growth phases.

This review discusses hair follicle organoids as emerging models for studying hair biology and disorders, emphasizing their promise for bridging basic research and clinical applications, but reports no new results.

The researchers reported that scaffoldin, a protein identified in chicken embryos, likely plays a role in forming periderm granules and contributes to the soft cornification of embryonic epidermis.

This study found that transplanting genetically modified dermal fibroblasts into full-thickness skin defects in rats led to the formation of hair follicles with mature pilosebaceous systems by 16 weeks.

In this study, researchers used advanced techniques to map the early embryonic development of mouse skin, identifying diverse cell populations and uncovering complex interactions essential for skin structure, signaling, and function.

In this research, LEF1 was identified as a crucial transcription factor for submucosal gland development in mouse and ferret tracheas, though it requires other factors to induce gland formation.

This abstract contains no research findings and pertains only to website navigation and policies.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

In this study, researchers observed that during zebrafish fin regeneration, osteoblast Erk activity, influenced by Fgf receptor signaling, forms gradients scaling with amputation length, which predicts regenerative tissue growth and skeletal structure size.

This study reports that Ca 2+ binding alters the dynamics and surface properties of PKD-like domains in Clostridium histolyticum collagenases, enhancing their stability and potentially aiding in collagen-targeting vehicle development.

This study observed that melanocytes in the outer root sheath of fetal scalp hair follicles may act as stem cells, showing rapid proliferation but immature function and morphology in culture.

Terrestrial vertebrates have balanced keratin gene clusters, unlike teleost fish.

In this study, researchers analyzing human fetal skin fibroblasts found eight distinct populations with developmental stage-specific abundance, identifying markers linked to fibroblast functions in blood vessel development, dermal layers, and hair follicle maturation.

This research suggests that hair keratins evolved from claw keratins in a hairless ancestor, with Hoxc13 controlling their expression in tetrapods, evidenced by the knockout of Hoxc13 hindering claw formation in Xenopus tropicalis frogs.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.
