This study found that stem cells from the human umbilical cord's Wharton's jelly may significantly enhance healing in excisional and diabetic wounds compared to controls.

Hair shape is determined by genetic, molecular, and cellular factors.

In this study, researchers demonstrated that the expression of the oncogene SmoM2 leads to basal cell carcinoma in the ear epidermis of mice but not in the back skin, with differences in susceptibility linked to the composition of the extracellular matrix.

This review discusses the interactions and signals affecting skin stem cells and their environments but reports no new experimental results; the authors highlight the need for understanding these processes to enhance tissue rejuvenation and repair.

This review discusses the role of iron from cosmetic sources in skin nutrition and reports no clinical results, highlighting its significance for skin, hair, and nail health.

This review discusses the role and interactions of the calcium-binding protein S100A6 in cellular processes and its association with various diseases, highlighting the need for further research to fully understand its biological impact.

In this study, women with PCOS who took 12 mg of Astaxanthin daily for 8 weeks showed a reduction in certain inflammatory markers and apoptosis-related genes, suggesting potential benefits for managing PCOS, though effects on symptoms like BMI and hirsutism were not significant.

This study provided the first proteome dataset for alopecia areata, revealing novel pathways in the disease mechanisms that may lead to new therapeutic targets.

This study found that TGF-β2 may enhance collagen expression and spheroid formation in human dermal papilla cells, which could improve their hair inductivity and maintenance.

In this review, researchers explored how PGC-1α might improve aged skin barrier function by influencing mitochondrial function and reducing inflammation, factors that are linked to epidermal health during aging.

This systematic review found that chitosan-based wound therapy may accelerate wound healing by reducing inflammation and modulating immune response, but notes limited clinical trials to date.

This review discusses the impact of immune-modifying therapies on COVID-19 vaccine responses, noting that a complete vaccine course can improve initially inadequate humoral responses among treated individuals compared to a single dose.

In this study, the combination of low level light therapy with arginine, arterial extract, or biotin tripeptide-1 was associated with improvements in hair density and follicle structure in androgenic alopecia.

This review examines the molecular effects of photobiomodulation therapy, particularly its influence on gene and protein expression related to inflammation and cell functions, but reports no new clinical results.

This review article evaluates new treatment techniques for androgenetic alopecia, including low-level laser therapy, platelet-rich plasma therapy, microneedling, and topical growth factors and peptides, reporting positive outcomes such as hair regrowth and improved hair density and thickness.

In this study, using a mouse model, researchers found that inducing senescence in hair follicle stem cells led to hair regeneration failure and sebaceous gland enlargement, akin to androgenetic alopecia features.

This study found that inhibiting PI3 kinase in epidermal stem cells reduces YBX1 phosphorylation, thereby decreasing cellular senescence and enhancing wound healing and regeneration in adult-derived skin models.

Ginseng and Albizia extracts help prevent hair thinning with age.

This preclinical study reported that the mix of biomimetic peptides, MGF, promoted hair growth and increased cell proliferation in cultured human hair follicles from AGA subjects.

This study found that subcutaneous injection of medroxyprogesterone acetate was more effective than intramuscular or topical treatments in reducing hair diameter for hirsute females.

This article integrates existing literature on hair follicle structure and formation at the cellular and molecular level, reporting no new findings.

This study observed that dermatological patients using certain immunosuppressants, like azathioprine and high-dose prednisolone, had a reduced humoral immune response to the Sinovac-CoronaVac COVID-19 vaccine compared to those without such treatments.

This research suggests that autism's genetic links are partially related to factors influencing physiological sex differences, with rare variants interacting with placental sex differences and common variants affecting steroid-related traits.

This review discusses how combining single-cell RNA sequencing and 3D bioprinting is advancing skin tissue engineering by enhancing cellular-level precision and addressing challenges like vascularization, ultimately improving regenerative outcomes and therapeutic strategies.

In this study, distinct immune and cellular profiles were observed in adults with atopic dermatitis associated with high levels of Staphylococcus aureus, including increased proinflammatory T cells and markers of skin barrier impairment, pointing to potential therapeutic targets for managing these interactions.

This study observed dynamic behaviors such as cluster formation, migration, and active proliferation of transplanted bone marrow cells in a mouse model, providing insight into cellular-level changes post-transplantation.

In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

This study explored the use of multiphoton microscopy to monitor changes in tumors and surrounding tissues in breast cancer patients undergoing neoadjuvant chemotherapy, finding it may effectively detect treatment response at cellular levels without using exogenous contrast agents.

This study found that adenine supplementation in cultured human follicle dermal papilla cells stimulated proliferation and reduced senescence, possibly through AMPK activation and increased cellular NAD+ levels.

In this study, Artemisia sieversiana extract was found to safely promote hair follicle dermal papilla cell growth and inhibit hair loss through anti-androgen, anti-inflammatory, and antioxidant effects at a cellular level.
