This study found that pen-type microwells enhanced hair follicle germ formation by promoting cell assembly, suggesting microwell array geometry significantly influences in vitro hair follicle development.

The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

This study found that epimorphin is closely linked to developing hair follicles in human fetuses, suggesting it plays a significant role in hair follicle morphogenesis.

This study found that while extracellular matrix components like hyaluronic acid promoted larger organoid formation, other matrix components hindered hair follicle germ assembly in an in vitro model.

This study developed a method for generating germ-like tissues called bbHFGs, which efficiently promoted hair follicle formation in mice, potentially advancing hair regenerative medicine applications.

This study reports that using activated platelet-rich plasma releasate in the preparation of bioengineered hair follicle germs enhanced follicular gene expression and significantly improved hair regeneration in vitro.

This study demonstrated a method for large-scale preparation of self-sorted hair follicle germs in vitro, which successfully generated hair follicles when transplanted into the skin of nude mice.

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 found that hyaluronic acid increased the size of hair follicle germ-like aggregates and the number of proliferative cells but did not maintain specific markers during the process.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

This study found decreased hair density and altered follicular architecture in the balding frontal scalp of patients with androgenic alopecia, with increased vellus hairs noted.

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 the creation of hair follicle lumens in mice is driven by the outward migration of keratin 79-positive cells, suggesting a novel mechanism for generating hollow cores in hair follicles.

This review discusses the development and advances in studying trichogenic dermal cells for hair follicle morphogenesis, summarizing methods, bioassays, and molecular markers, but reports no new research findings.

In this mouse study, NF-κB was shown to play a role in hair follicle cycling and morphogenesis, with specific activity patterns differing by hair type and involving noncanonical signaling for zigzag hair bending.

This study developed an in vitro artificial hair germ model using dermal papilla cells and skin keratinocytes to explore early stages of hair follicle regeneration.

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

Basonuclin is crucial for hair follicle development and cycling in mice.

This study reports two cases of trichoblastic neoplasms with histologic features suggesting they may be distinct, locally aggressive trichoblastic carcinomas separate from basal cell carcinoma.

Stem cells in developing hair follicles move to specific areas as they mature.

In this report, researchers describe an unusual case of congenital pili multigemini, a hair follicle disorder, presenting on the eyebrow of a female infant, highlighting its rarity and atypical location.

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.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

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 found that disrupting the inturned gene in developing mouse epidermis halted hair follicle formation due to impaired keratinocyte differentiation, highlighting primary cilia's role in tissue-specific planar cell polarity signaling.

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 found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

This study suggests that hair removal lasers, potentially combined with topical minoxidil, may target and treat the underlying mechanisms of trichoepithelioma lesions effectively, though clinical trials are needed to verify this approach.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.
