This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study suggests that nerve growth factor may support hair follicle growth in Liaoning cashmere goats through pathways involving its receptor, TrkA, particularly during the anagen phase.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

This study found that macrophages play a crucial role in nerve regeneration by regulating Schwann cell dynamics and remyelination, with Gas6 identified as a key factor in this process.

This study in neonatal chicks reported that intense sound exposure severely impaired auditory function, but function returned to near normal within 3 days, primarily due to non-hair-cell mechanisms.

In this study, transplantation of hair follicle stem cells and nerve growth factor-modified stem cells significantly reduced amyloid deposition and tau hyperphosphorylation in an Alzheimer's disease rat model, suggesting potential as a treatment option.

This study reported that a novel chitosan/polyvinyl alcohol nanofiber sponge effectively enhances the hair follicle-inducing ability of dermal papilla multicellular spheroids in a mouse model.

This chapter discusses the structure and function of the skin, detailing its protective roles and the layers that comprise it, but reports no new research findings.

This study found that androgen receptor inactivation in male and female mice reduced susceptibility to DMBA-induced skin cancer, but the effect varied by the carcinogenesis model.

The authors suggest that male-pattern hair loss may be linked to neuropathy caused by tension on scalp nerves, potentially worsened by testosterone, and propose electrical stimulation as a temporary treatment.

Understanding skin structure and development helps diagnose and treat skin disorders.

This study found that brain-derived nerve factor protein expression was significantly increased in balding scalp samples from men with androgenetic alopecia, suggesting it may play a role in hair follicle regulation.

In this study, researchers used NIR-II fluorescence imaging to track the survival and migration of EPI-NCSCs in rat models, finding that these stem cells aided in repairing facial nerve defects when applied via acellular nerve allografts.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

This chapter reviews therapies for skin and corneal regeneration and hair loss, discussing various treatments but presenting no new research findings.

This study demonstrated that keratin derived from human hair can improve axon extension and alleviate motor deficits from sciatic nerve injuries, highlighting its potential as a promising biomaterial for peripheral nerve regeneration.

This study observed significant differences in hair care practices and biologic hair parameters between Caucasian and African American women, which may contribute to varying hair fragility and growth.

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

This review discusses the potential for surface-modified nanostructured lipid carriers to enhance hair regrowth by improving drug absorption and stability, focusing on their use with agents like minoxidil and finasteride for hair loss treatment.

This study observed that deleting PTEN in mouse facial motoneurons enhanced peripheral axon regeneration but also led to physiological changes and potential hyperplasia in older mice.

This study found no evidence supporting the hypothesis that Aβ afferents sprout into the superficial laminas of the spinal cord after nerve injury in rats.

This study concluded that early-stage tissue-engineered skin substitutes, developed using skin progenitor cells, had a better graft efficiency and supported hair follicle formation, which may improve wound healing outcomes.

This study found that a biomaterial gel made from human hair keratins facilitated nerve regeneration in an animal model, potentially matching the effectiveness of traditional autografts.

This review highlights essential preoperative assessments for ophthalmologists and non-oculo-facial surgeons performing upper facial rejuvenation, emphasizing the importance of understanding ocular and periocular anatomy to achieve both cosmetic and functional improvements.

This study found that improved outcomes in scalp surgery were achieved by utilizing knowledge of the surgical anatomy of the scalp to avoid complications like unsightly scars and distorted hair patterns.

In this study, the aim was to define the indications, diagnostics, and surgical techniques for eyebrow lift procedures, noting that the primary complication is a visible scar, especially concerning for individuals with a tendency for keloid formation.

This review derived guidelines for scalp surgery suggesting improved outcomes when avoiding neurovascular structures, preserving tissue integrity, and maintaining hair direction, but it reports no new clinical results.

In this study, the researchers found that a keratin hydrogel filler in nerve conduits led to earlier Schwann cell migration and improved cellular behaviors compared to other fillers in a rat sciatic nerve model.
