Obesity is a worldwide epidemic that predisposes individuals to many age-associated diseases, but its exact effects on organ dysfunction are largely unknown1. Hair follicles-mini-epithelial organs that grow hair-are miniaturized by ageing to cause hair loss through the depletion of hair follicle stem cells (HFSCs)2. Here we report that obesity-induced stress, such as that induced by a high-fat diet (HFD), targets HFSCs to accelerate hair thinning. Chronological gene expression analysis revealed… 

Regulation and dysregulation of hair regeneration: aiming for clinical application

By analyzing the dysregulation of hair regeneration under pathological conditions, this work can better address the complex interactions among stem cells, the differentiated progeny, and mesenchymal components, and highlight the critical role of macroenvironment adjustment that is essential for hair growth and regeneration.

Dysregulated behaviour of hair follicle stem cells triggers alopecia and provides potential therapeutic targets

Recent findings on how HFSC metabolism, ageing and the microenvironment give rise to hair growth disorders, as well as related genes and signalling pathways are summarized.

Toward Elucidating Epigenetic and Metabolic Regulation of Stem Cell Lineage Plasticity in Skin Aging

This review discusses recent studies that proposed molecular mechanisms that drive the degeneration of hair follicles, a major appendage of the skin, and summarizes literature on genotoxic stress, nutritional sensing, metabolic rewiring, mitochondrial activity, and epigenetic regulations of stem cell plasticity.

Perspectives on miRNAs Targeting DKK1 for Developing Hair Regeneration Therapy

Light is shed on the perspectives of miRNA-mediated hair growth for treating AGA via regulating DKK1 and, eventually, modulating Wnt/β-catenin signaling.

Hydra and the hair follicle – An unconventional comparative biology approach to exploring the human holobiont

It is argued that general principles of how Hydra manages its microbiota can inform the development of novel, microbiome‐targeting therapeutic interventions in human skin disease.

Integrated Transcriptomics and Metabolomics Analyses of Stress-Induced Murine Hair Follicle Growth Inhibition

This study established a chronic restraint stress (CRS)-induced hair growth inhibition mouse model and performed a comprehensive analysis of metabolomics and transcriptomics, finding that numerous genes associated with metabolism were significantly changed in CRS-inducedhair growth inhibition.

Role of Diet in Stem and Cancer Stem Cells

A deep understanding of the specific dietetic requirements of normal and cancer stem cells may pave the way for the development of nutrition-based targeted therapeutic approaches to improve regenerative and anticancer therapies.

Morphogenesis, Growth Cycle and Molecular Regulation of Hair Follicles

The structure, development, cycle and molecular regulation of hair follicles are reviewed in order to provide new ideas for solving diseases and forming functional hair follicle.



Hair follicle aging is driven by transepidermal elimination of stem cells via COL17A1 proteolysis

The fate analysis of HFSCs during aging revealed that organ aging is primed by the sustained DNA damage response against DNA damage that accumulates in renewing stem cells during aging.

High fat diet enhances stemness and tumorigenicity of intestinal progenitors

It is shown that high-fat diet (HFD)-induced obesity augments the numbers and function of Lgr5+ intestinal stem cells of the mammalian intestine and highlights how diet-modulated PPAR-δ activation alters not only the function of intestinal stem and progenitor cells, but also their capacity to initiate tumours.

Distinct types of stem cell divisions determine organ regeneration and aging in hair follicles

It is reported that hair follicle stem cells (HFSCs) lose their regenerative capabilities during aging owing to the adoption of an atypical cell division program, and this results demonstrate that distinct stem cell division programs may govern tissue and organ aging.

Roles of MED1 in quiescence of hair follicle stem cells and maintenance of normal hair cycling.

Flow cytometric analysis revealed that the numbers of hair follicle bulge stem cells were reduced in Med1(epi-/-) mice from a few months after birth, suggesting that MED1 has roles in maintaining quiescence of keratinocytes and preventing depletion of the follicular stem cells.
