The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This review discusses age-related changes in scalp skin and their potential effects on hair follicle aging, but reports no new clinical results, calling for further investigation.

This study found that formulation factors like pH, viscosity, and chemical enhancers can significantly influence intrafollicular hydrocortisone permeation in vitro, with higher pH and enhancers reducing follicular contribution.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

In this study, fetal stem cells were identified in adult human hair follicles long after childbirth, indicating potential for autologous therapies due to their pluripotent characteristics.

This study developed a method to culture and maintain chicken feather follicles in vitro, preserving structure and biology similar to their in vivo state, though some gene expression was altered.

The document explains how hair follicles develop, their structure, and how they grow.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.

This integrative review developed a Spiral Model to better represent human hair follicle dynamics and aging, which may assist in distinguishing natural aging from pathological changes and improving trichological interventions.

This study highlights that current research efforts to deliver anti-acne drugs to hair follicles have primarily targeted healthy follicles, overlooking the distinct characteristics of pathologically clogged follicles in acne vulgaris.

This study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This article provides contact information for Bruce A. Morgan and features no new research findings.

This study found that human hair follicles express ATP-sensitive potassium channels, suggesting that minoxidil acts on these channels and that drugs targeting them may treat hair disorders.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This study found that PGD2 inhibits hair follicle regeneration in mice through the Gpr44 receptor, suggesting that blocking PGD2 or Gpr44 may enhance skin regeneration after wounds.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This review discusses recent findings on hair follicle morphogenesis and regeneration, focusing on molecular signals and stem cells, and suggests that understanding these processes may aid in developing new strategies for wound healing.

This article reviews methods to enhance epithelial–mesenchymal interactions for hair follicle bioengineering but does not present new experimental results; it emphasizes optimizing combinations for successful regeneration.

This study suggests that a sandwich-structured wound dressing with bioceramic and polylactic acid layers may improve burn wound healing by absorbing exudates and promoting hair follicle regeneration.

This study found that DKK1 and WNT10b are paracrine factors that modulate hair follicle stem cell differentiation inhibition, contributing to androgenetic alopecia by affecting Wnt signaling in androgen-sensitive dermal papilla cells after dihydrotestosterone stimulation.

Hair follicles in people with alopecia have lower levels of a key blood vessel growth protein.

This review explores the relationship between hair follicles and wound healing, emphasizing the importance of translating scientific findings into practical therapies for chronic wounds, but it reports no new experimental results.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

This review synthesizes recent findings on the hair follicle stem cell niche and its complex interactions, exploring potential pathways for developing new hair growth therapies; it reports no new clinical results.

This review discusses the role of the immune niche in hair follicle regeneration and its impact on different forms of alopecia, highlighting research gaps and potential therapeutic strategies.

This study found that the transcription factor Gata6 plays a crucial role in adult mouse hair follicle regeneration by promoting the renewal and preventing DNA damage of rapidly proliferating progenitor cells.

This study found that a cocktail of three proteins from embryonic skin can enable adult fibroblasts to regenerate hair follicles by altering gene expression and activating regenerative signaling pathways.
