This study found that thymus transplantation in athymic mice resulted in T-cell-driven hair follicle depigmentation and loss, without multiorgan autoimmune disease, highlighting mechanisms of tissue-specific tolerance.

This study presents evidence that specific thymus-derived peptides affect human hair follicle growth, identifying thymulin as a potential hair growth stimulator despite interindividual response variations.

In this study, 150 kHz electromagnetic radiation reduced the number and size of follicular cysts in a rat model of polycystic ovary syndrome without causing significant morphological damage to developing follicles.

The researchers reported that Gambogic Amide may prevent hair greying and promote hair growth by maintaining follicle pigmentation in vitro through activation and migration of melanocytes.

This study found that chronic stress may inhibit hair follicle growth and melanogenesis in mice through modulation of the central HPA axis, with C57BL/6 mice appearing most sensitive to these effects.

This study found that scalp hair follicles had higher expression of cytokeratin 15 and distinct hair layers compared to other body regions, highlighting differences in hair follicle characteristics.

This review summarizes major growth factors that promote hair follicle growth, but it reports no new experimental findings.

This study observed that downregulation of laminin-511 plays an important role in hair regression during the catagen stage in mice.

In this study, 0.5% timosaponin BII from Anemarrhena asphodeloides promoted hair growth in C57BL/6 male mice, showing effects comparable to 2% minoxidil.

In this study, researchers reported that adenosine stimulated hair shaft elongation in cultured human hair follicles by promoting proliferation and prolonging the anagen phase, suggesting the A2B adenosine receptor in outer root sheath keratinocytes as a promising target for treating hair growth disorders like alopecia.

This study found that Oriental melon leaf extracts promoted hair growth in a mouse model and cultured human hair follicles, suggesting potential use as a treatment for hair loss.

In this study, topical acyclovir significantly delayed hair growth initiation and completion in mice and reduced hair follicle size, suggesting potential inhibitory effects on hair growth.

This study found that patients with androgenetic alopecia had increased scalp microbial diversity and reduced Staphylococcus abundance, particularly in the frontal and vertex regions, suggesting this dysbiosis as a sensitive indicator of AGA.

This study found that the prenatal skin development in Red Sokoto goats undergoes significant morphological changes across gestational stages, which may be important for their adaptation and thermoregulation after birth.

In this study, researchers examined the histological structure of wild boar skin from three anatomical regions and found it comprises three main layers: epidermis, dermis, and hypodermis, containing various cell types and structures such as hair follicles, sebaceous glands, and fat cells.

Multiple-wavelength radiation helps hair grow by boosting early hair follicle development.

This study found that elastin-like recombinamer (ELR) wound dressings promote tissue regeneration and stability without rejection in ex vivo and in vivo models, indicating potential for hard-to-heal wound treatment.

In this study, freezing gamma-irradiated amniotic fluid increased hair follicles and accelerated the transition to the anagen stage in rats, suggesting potential for treating hair loss safely and effectively.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

This study found that nanovesicles derived from ReNcell VM cells promoted hair growth in mice by activating the Wnt/β-catenin signaling pathway, suggesting they may serve as an alternative to extracellular vesicles for hair growth therapy.

This study identified two distinct fibroblast subsets in mouse skin, revealing that adult skin scarring occurs due to the repair process utilizing only one, lineage-restricted fibroblast type instead of coordinated diverse populations.

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 review discusses recent advances in surface modification and endothelialization of biomaterials for vascular grafts, highlighting promising methods like gene engineering and targeting ligand immobilization to improve clinical outcomes.

This study found that IL-17A-producing γδ T cells play a key role in bone fracture healing by promoting bone formation, with deficiencies leading to impaired repair in mice.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

In a mouse model, this study demonstrated that a microneedle patch system using keratin and integrated with MSC-derived exosomes and UK5099 promoted hair regrowth more efficiently than traditional delivery methods.

This review discusses the effects of hormonal treatments on the physical and mental health of transgender individuals, reporting significant reductions in mental health issues following treatment, but calls for more research on long-term and nonbinary outcomes.
