This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that CD34 is necessary for TPA-induced activation of hair follicle stem cells and tumor formation in mice, with CD34 knockout mice showing delayed and reduced tumor development compared to wild-types.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This study found that skin-derived precursor cells in mice can originate from both neural crest and somite lineages but show functional similarities regardless of their developmental origins.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

This study found that lymphatic vessels in mice are important for hair follicle development and organization, as their depletion blocks hair growth.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study suggests that prolactin has complex, gender- and location-dependent effects on human hair follicles, promoting hair growth in female frontotemporal scalp areas while inhibiting it in male occipital regions.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

This study found that foot shock stress prolonged the telogen stage and delayed anagen induction in the hair cycle of non-depilated mice, potentially through stress-induced actions of substance P.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

This study suggests that Thyroxine (T4) may promote key features of human skin wound healing, such as re-epithelialization and angiogenesis, in an ex vivo model.

This study reported the feasibility of detecting six cell-cycle-related nuclear markers in plucked human scalp and eyebrow hair, providing valuable insights for future intervention studies.

In this study, researchers identified a gene expression pre-pattern and implicated the Wnt inhibitor Dickkopf 4 in the formation of color patterns in domestic cat embryos.

This study demonstrates that keratinocyte cell lines derived from cultured hair follicles can fully differentiate in organotypic skin models, offering a minimally invasive alternative to obtaining keratinocytes for research.

This study found that exposure to 12-O-tetradecanoyl-phorbol-13-acetate in mouse skin caused changes in claudin expression and localization, indicating disruption and eventual recovery of the epidermal barrier.

This study found that elevated expression of the protein Zyxin in hair follicles is associated with androgenetic alopecia and suggests it may be targeted for therapy.

This study suggests that high proliferative activity and peripheral invasion are key indicators of malignancy in canine sebaceous gland tumours. It also reports a higher incidence of circumanal gland and testicular tumours, indicating a possible androgen-related pathway in tumour development.

This study found that platelet-rich plasma therapy led to significantly increased hair growth and density compared to placebo in patients with androgenic alopecia over six months.

This study found that rhamnose can restore hair-inducing gene expression in dermal papilla cells and accelerate hair follicle regeneration by promoting the hair cycle into the anagen phase, suggesting its potential therapeutic application for alopecia treatment.

In this study, researchers differentiated human induced pluripotent stem cells into dermal papilla-like cells and observed gene expression dynamics during five stages of dermal differentiation, demonstrating the potential of these cells to interact with epidermal cells in functional assays.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This study observed that gerbils exhibit a different wound healing mechanism compared to mice, with lower TGF-B1 expression and distinct tissue responses, yet achieve similar healing outcomes.

In this study, XMU-MP-1 unexpectedly reduced cell proliferation and altered cell cycle progression in a model human hair follicle, possibly due to off-target kinase inhibition.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This review discusses the pathogenesis and challenges in treating primary cicatricial alopecia, highlighting the need to understand immune protection collapse in hair follicle stem cells; it reports no new clinical results.
