This study observed initial hair regrowth in a businessman with alopecia areata universalis treated with tofacitinib, but the effect diminished, leading to renewed hair loss.

This source reports that scalp cooling is currently the only safe and FDA-cleared method to potentially reduce chemotherapy-induced hair loss, with about a 50% chance of maintaining sufficient hair to avoid needing a wig.

This review discusses chemotherapy-induced alopecia, highlighting its pathogenesis, clinical patterns, and current therapeutic approaches, with no new clinical results reported.

This study found that glioblastoma cancer stem cells avoid immune suppression by downregulating TLR4, and restoring TLR4 signaling may reduce tumor growth and self-renewal.

In this study, basal cell carcinoma developed in Ptch-deficient mice only after chemical treatment, not skin wounding, suggesting a second unknown event is necessary for tumor formation.

The authors find the endoscopic forehead midface lift to be a reliable and safe method for facial rejuvenation.

SA linked to mitochondrial issues and oxidative stress, while AGA involves disrupted hair growth genes.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.

This study found that cardiac fibroblasts significantly enhance the maturation of neonatal mouse and human embryonic stem cell-derived cardiomyocytes, suggesting a pivotal role in postnatal heart development and disease.

This study reports that generalized discoid lupus erythematosus is a recognized canine variant of cutaneous lupus erythematosus, resembling its human counterpart, with varied treatment responses and common relapses.

This study describes recurrent or persistent follicular dysplasia and interface dermatitis in Boxers, noting concurrent courses and potential influences from photoperiod or genetics, but without identifying the condition's exact causes.

This review discusses experimental data, technologies, and genetic factors related to stem cell niches, highlighting their role in tissue regeneration and diseases, but reports no new results.

This review examines how epigenetic dysregulation affects adult stem cell function, noting that impacts range from minor to serious disruptions in tissue homeostasis and potential cancer development.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

This review explores how adipose-derived stem cells contribute to skin homeostasis and highlights recent advances in their clinical applications in dermatology, but it reports no new clinical results.

This review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This study found that overexpression of miR-214 in keratinocytes inhibits hair follicle development and cycling by targeting β-catenin in the Wnt signaling pathway.

This study found that newborn mouse skin organoids can robustly grow hair in vivo, while adult organoids require specific interventions to restore their hair-forming ability.

This review discusses melanocyte development, emphasizing the plasticity of melanoblasts and the role of both intrinsic and extracellular signals in their differentiation and migration, with no new clinical results reported.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This review discusses the roles of immune responses and cells in skin health and disease, emphasizing recent insights into their mechanisms and potential therapeutic applications, but presents no new experimental results.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

This review discusses the various roles of RANK signaling in bone remodeling, immune function, and epithelial differentiation, highlighting its potential involvement in cancer mechanisms; it reports no new clinical results.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

This review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

This review synthesizes recent findings on the hair follicle stem cell niche and its complex interactions, exploring potential pathways for developing new hair growth therapies; it reports no new clinical results.

This review explores potential indications for prolactin receptor inhibitors beyond breast and prostate cancers, emphasizing the need for potent antibodies to further research prolactin receptor expression.
