This study identified the transcription factor Elf5 as a novel regulator of keratinocyte proliferation and differentiation in skin, with expression elevated in stem/progenitor cell populations, suggesting its potential role in determining cell fate during skin and hair development.

In this study, researchers reviewed the roles of autophagy and mitophagy in hair follicle cycles, exploring their potential links to hair loss and investigating how manipulating these pathways might offer new therapeutic strategies.

This study used single-cell RNA sequencing to characterize 19 distinct cell populations in sheep hair follicles, uncovering differentiation signatures and intercellular communication that may influence wool curvature and sheep breeding.

This case study reports on a rare benign skin tumor known as Pilomatricoma in the lower left orbital region of a 32-year-old male, highlighting its characteristic histopathological features and emphasizing the importance of surgical excision for successful treatment and minimal recurrence risk.

This study reports that the composite galeal frontalis pericranial flap can be successfully used for reconstruction in anterior cranial base surgery, effectively sealing cerebrospinal fluid leaks, while minimizing complications like numbness and skin necrosis.

This case report describes a twenty-year-old woman misdiagnosed with a sebaceous cyst that was actually pilomatrixoma, a benign skin lesion from hair matrix cells, confirmed by histopathology after excision.

Crickets have genetically controlled hair plates that help them sense and move their antennae.

This study found that Sox9 plays a critical role in maintaining radial glial progenitor cells and regulates the timing of their generation of upper-layer cortical neurons.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This study found that the corneal epithelium differentiation program can proceed independently of lens formation, suggesting the corneal program is the default in eye development.

This study found that Krox20 marks a diverse stem cell population in mouse hair follicles, which significantly contributes to the interfollicular epidermis and regulates epidermal homeostasis.

Cortexolone 17a-propionate may be an effective new treatment for hair loss.

Keratin-associated proteins are crucial for hair strength and structure.

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

This study introduced a new classification system for distinguishing between anagen VI and early catagen stages in human hair follicle organ culture, using it to confirm eflornithine's ability to induce premature catagen.

This study demonstrated that HOXC13 directly influences hair keratin gene expression by binding to specific DNA motifs, suggesting its role in early hair follicle differentiation.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This study found that small proline-rich proteins modify the biomechanical properties of cornified cell envelopes in rodent forestomachs, potentially affecting the tissue's ability to withstand mechanical stress.

This review explains the genetic diversity of sheep wool keratin-associated protein genes and explores how this variation might be leveraged for selective breeding to enhance wool fiber traits.

This review discusses the effects of IGF-1 on hair follicle cell proliferation and differentiation, highlighting its roles in paracrine signaling, apoptosis prevention, and hair growth, but reports no new clinical results.

This review highlights recent advances in chitosan-based nanoparticles (CS NPs) for drug delivery, discussing their modifications, preparation methods, production with organic and inorganic materials, and their latest implementations in the field, emphasizing the role of CS NPs in improving drug transport and release properties.

Gene expression in wool follicles changes with growth cycles, offering insights into wool and human hair growth.

This study found that interleukin-1 directly induces the expression of keratin 6 in keratinocytes, which is a marker of activation and involved in inflammatory skin responses.

This review discusses factors affecting hair aging and the current pharmacological treatments for androgenetic alopecia, mentioning topical minoxidil and oral finasteride, but does not present new clinical findings.

In this study, researchers found that simple hair clipping in mice induced dynamic plasticity and axogenesis in skin sensory axons, linked to follicular activation and HGF signaling.

This review examines the chemical composition and potential health risks of hair straighteners, but it reports no new findings and emphasizes the importance of understanding hair fibre structure for safe use.

In this study, researchers found that connexin 43-negative cells in the basal layer of the epidermis could serve as markers for keratinocyte stem cells, aiding their identification and separation.

This study demonstrated that anagen can be induced in Stat3-disrupted mice, suggesting that both Stat3-dependent and independent pathways, possibly involving PKC, mediate hair cycle progression with required PI3K activation.
