This study observed that subcutaneously implanted mixtures of human hair follicle cells in nude mice resulted in the formation of hair follicle-like structures, suggesting potential for hair regeneration.

In this study, local injection of nanosized recombinant human erythropoietin at the injury site improved skin regeneration and re-epithelialization in a mouse model of deep second-degree burns through coexpression of specific receptors.

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 article reviews the structure and function of the skin and its importance for understanding skin diseases, without providing new clinical results.

This article reviews over 1000 skin diseases affecting patients' quality of life and highlights the importance of understanding skin biology and pathology, but provides no new results.

This study found that in patients with non-cicatricial alopecia, hair follicles and their sheaths were thinner compared to controls, especially in cases of alopecia areata and telogen effluvium, with notable thinning beginning in the subcutaneous fat tissue.

In this study, researchers found that patients with non-scar alopecia exhibited thinner hair sacs and root sheaths compared to a control group, with significant thinning observed in cases of alopecia areata.

This study found that JAM-A modification in mouse wound models significantly promoted wound healing and fibroblast proliferation, potentially linked to increased levels of growth factors bFGF and EGF.

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.

This review discusses recent advances in noninvasive hair imaging technologies, such as global photography, trichoscopy, reflectance confocal microscopy, and optical coherence tomography, highlighting their potential to improve hair diagnostics and treatment monitoring, while also outlining their clinical applications and limitations.

This review discusses age-related changes in scalp skin and their potential effects on hair follicle aging, but reports no new clinical results, calling for further investigation.

This study examined the subcutaneous structures in forehead creases using cadavers and observed that dense fibrous structures connecting the dermis to the frontalis muscle, as well as specific epidermal and dermal characteristics, may contribute to the formation of these creases.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

In this study, a subcutaneous injection of recombinant RSPO1 was found to activate hair follicle stem cells and enhance hair regeneration in mice by stimulating the Wnt/β-catenin signaling pathway, suggesting its potential as a treatment for hair loss.

This study reports that transplantation and in vivo reprogramming using specific reprogrammed cell types can generate skin appendage-like structures in adult mice, suggesting potential therapeutic avenues for skin regeneration and disorders.

This study observed that multiphoton excitation microscopy revealed changes in vascular structure and hair papillae in mice subcutaneous tissue following cyclophosphamide treatment for chemotherapy-induced alopecia.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This study observed that during the postnatal development of gray short-tailed opossums, skin transitions from facilitating gas exchange through a dense capillary network at birth to supporting thermoregulation, with significant changes in skin thickness and structure occurring by 35 days old.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This study found that patients with androgenetic alopecia had thinner scalp and subcutaneous tissues, narrower and shorter hair follicles, a lower hair follicle count, and fewer color flow signals compared to healthy volunteers, as measured by 22 MHz ultrasound.

The skin is essential for protection, temperature control, and immune defense.

This study reports that the mechanical interactions between human skin and adjacent subcutaneous white adipose tissue influence the appearance of skin wrinkles, with sWAT reinforcement potentially more effective for reducing signs of skin aging than skin reinforcement alone.

This review discusses the multifunctional role of subcutaneous adipocytes, their contribution to metabolic and pathological processes, and reports no new experimental results; it suggests potential protective roles against metabolic syndrome.

This study found that keratin scaffolds derived from human hair promoted excellent cell viability and showed minimal inflammatory response and vascular integration when tested in in vitro and in vivo settings.

This study found that subcutaneous isotretinoin in male hamsters reduced sebaceous gland size without affecting other androgen-dependent skin structures, while etretinate had no effect.

This study found that cyclosporin A treatment in young nude mice induced dose-dependent hair growth, which stopped after treatment cessation, but did not result in hair growth in older mice.

This paper reviews the complex histology of skin layers and underscores its importance for accurate and reproducible diagnosis in cutaneous pathology, but reports no new research findings.

This case report describes a 42-year-old male with alopecia areata and a scalp neurofibroma, emphasizing the tumor's histopathological features and the patient's decision against surgical treatment.

This study found that dermal papilla cells and dermal sheath fibroblasts can induce hair follicle formation when combined with hair follicle epithelial cells, both in vitro and in vivo in nude mice.
