In this study, bioengineered hair germ microspheres made from HME hydrogels promoted hair follicle regeneration in vivo, suggesting a promising approach for hair loss treatment.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This study evaluated the protective effects of a hair conditioner containing rice derivatives on natural Caucasian hair using various analysis methods and found that the conditioner, especially with rice germ oil GX-N, effectively improved hair properties even under stress conditions like irradiation.

This study found that inducing miR-205 reduces actin contractility and stiffness in hair follicle stem cells and progenitors, stimulating hair regeneration in both young and old mice.

This study found that overexpression of the anti-apoptotic protein Bcl-2 in mice disrupted cell death during the hair cycle, impairing hair regeneration by delaying anagen entry and hair growth.

In a mouse model, this study found that intradermal keratin injection stimulated hair growth and suggested its potential use for treating hair loss by promoting hair regeneration.

Sox13 is a new marker for early hair follicle development and differentiation.

In this study, Sox13 was identified as a novel marker for early hair follicle development and differentiation in mice, though it appears to be dispensable for overall epidermal and adnexal development.

This study found that human hair follicles can be used to generate induced pluripotent stem cells, which can then efficiently differentiate back into keratinocytes.

This study suggests that the expression patterns of keratin and filaggrin indicate milia may originate from the outermost cells of the hair bulge in the outer root sheath.

In this animal study, zinc deficiency in mice was linked to disrupted hair cycles and impaired hair regrowth, which were reversed by zinc supplementation.

This study provides a comprehensive platform to explore stem cell interactions regulating hair follicle growth, revealing key signaling pathways in epithelial-mesenchymal interactions using advanced RNA sequencing and transgenic reporters.

Valentina Greco's research shows that the environment around hair follicle stem cells is more crucial for regeneration than the stem cells themselves.

Keratin 79 cells help form and regenerate hair canals.

This review discusses the role of BMP/Wnt signaling in regulating stem cell homeostasis and activation but reports no new experimental findings.

This study assessed the effects of a formulation containing millet extract, wheat germ oil, L-cystine, and calcium pantothenate on women with telogen effluvium using Digital Phototrichogram, but it reports no new results.

Finasteride lowers PSA levels in men, certain factors increase testicular cancer risk, and current guidelines for penile cancer may lead to unnecessary surgeries.

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.

This study found that hair germ and epidermal basal cells differ in keratin expressions in rat hair tissues, with hair-specific keratins appearing after the differentiation of each layer.

This review discusses recent advancements in hair follicle regeneration technologies, including the authors' own development of functional hair regeneration through bioengineered follicle germ transplantation, but reports no new clinical results.

This study found that the phenotype of Hedgehog/Gli-driven skin tumors in mice depends on the cell of origin, tissue context, and level of oncogenic signaling.

This study found that RANK-RANKL signaling regulates hair renewal and epidermal homeostasis in mice, revealing its role in initiating hair growth cycles and maintaining skin cell activity.

In this study, mouse sweat gland development relied on a regulatory sequence initiated by Wnt/β-catenin signaling, and disruptions in Wnt, Eda, or Shh pathways led to distinct developmental failures.

This study found that circadian clock genes are involved in regulating the hair growth cycle, suggesting a connection between daily rhythms and the longer hair follicle cycling process.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

Basonuclin helps identify and track hair follicle development and cycling in mice.

This study identified a proliferative intermediate transcriptional state associated with the transition from secondary hair germ cells to lower hair follicle-associated cells during early hair follicle regeneration in mice.

In this study, researchers developed a novel therapy using the secretome of human fetal cartilage progenitor cells, which successfully regenerated functional hair follicles in animal models and significantly increased hair regrowth, suggesting potential as a new treatment for androgenic alopecia.

In this study, topical inhibition of casein kinase 1 in mice was found to enhance melanocyte precursor migration and eumelanin production, suggesting potential applications for treating vitiligo and graying hair through KitL/c-Kit signaling pathway activation.

This study used infrared spectral imaging to show for the first time the distribution of glypican-4 and glypican-6 in hair follicles across different growth phases, highlighting the potential of this technique for studying alopecia.
