This study found that the loss of papillary fibroblasts in the skin due to UV radiation is mainly caused by an uncontrolled inflammatory response, with T cells helping fibroblast survival.

This study found that epidermal growth factor receptor and mitogen activated protein kinase inhibitors down-regulate PD-L1 expression in human hair follicles, which may contribute to sterile folliculitis in treated patients.

This study reports that tissue-engineered skin using ES cell-derived epidermal stem cells and collagen sponge successfully healed full thickness skin defects in mice, forming epidermis and structures resembling glands and hair follicles.

In this animal study, ginsenoside Rb1 demonstrated therapeutic effects on hypertrophic scar remodeling, with the highest efficacy observed at a dose of 0.56 mg.

The report suggests a possible link between hair loss and hidden scalp tumors but states more evidence is needed to confirm this.

This case report describes a 9-year-old Korean boy with a calcified nodule on his earlobe, confirmed by histopathologic examination and Von Kossa staining.

This case report details atrichia with papular lesions in a 4-year-old girl, highlighting specific histological findings on her scalp and other affected areas.

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.

In this study, retinoic acid treatments induced glandular and feather formation in embryos by altering positional values and activating specific retinoic acid nuclear receptor gene expression.

This case report describes the presence of a teratoma within an equine antral follicle and suggests that the ovary maintained functionality despite the teratoma, as indicated by active antral follicles and recent ovulation.

Early-stage skin substitutes improve wound healing and skin structure.

This case report suggests that venlafaxine may cause hair loss in some patients, as demonstrated by a patient whose hair loss ceased after stopping the medication.

This study found that participants with normal hemoglobin but low ferritin experienced significantly more symptoms like restless leg syndrome, dizziness, and shortness of breath compared to those with normal ferritin.

This study found that patients with severe acne vulgaris had different systemic inflammatory indices and hematologic parameters compared to healthy individuals.

This study reports that extracellular microvesicles isolated from stimulated dermal fibroblasts enhanced hair follicle growth ex vivo and identified norrin as a novel modulator in hair regeneration processes.

In this case series, two cats with hypothyroidism and hyperthyroidism achieved clinical remission and normal thyroid function following timely diagnosis and targeted treatment with levothyroxine and methimazole, respectively.

This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.

This study revealed that deficiency in the enzyme FA2H in mice affected sebaceous gland function, altered sebum composition, and caused cycling alopecia, highlighting FA2H's role in hair follicle homeostasis.

Early stage bald spots are linked to skin inflammation and damage to the upper part of the hair follicle.

This study suggests the mechanical effect of injecting a solution is more important than the solution's nature in treating atrophic acne scars, with UBM sonography proposed for objective assessment.

In this study, researchers found that the expression of vimentin, desmin, and laminin in rat skin contributes to cell structure and tissue integrity, with varying reactions across different cell types.

This study reported that novel adipose slurry injections improved rhytides and dermis density in patients receiving facial wrinkle treatments based on evaluations at multiple follow-up intervals.

This study found that radiation negatively impacts the survival and proliferation of fibroblasts on human dermis transplants, but hair follicle pores enhance cell viability even after irradiation.

This study observed that EZH2 expression scores in the epidermis, dermis, and hair follicles decrease with gestational age in human fetuses, and these scores were significantly higher in adults, indicating that lower EZH2 levels may be required for full skin differentiation and maturation before birth.

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.

This study found that prolactin can induce premature catagen in both mouse and human hair follicles and suggests that targeting prolactin and TGF-β receptors may be promising for treating androgenetic alopecia.

As skin ages, it gets thinner, paler, and more wrinkled, and protection and care like sunblock and moisturizers are important.

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

This study found that activating the Sonic hedgehog pathway in scarring wounds can remodel the dermis to promote hair follicle regeneration, highlighting a potential new approach to enhance healing.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.
