This case report describes a successful treatment of sarcoidal foreign body reactions caused by permanent makeup ink with local steroid injections, while also identifying the involvement of M2 macrophages in the reaction.

PEVs effectively deliver minoxidil through skin.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

Lower GATA3 levels in mice help hair regrow by changing certain immune cells.

In this review, bioengineered materials incorporating growth factors and cytokines were reported to enhance wound healing by sustaining drug delivery, reducing dosage, and minimizing side effects compared to traditional treatments.

This study suggests that exosomal miRNAs from human amniotic fluid stem cells may inhibit myofibroblast differentiation and reduce fibrotic scarring in wound healing.

This case report documents the first known instance of an ectopic sebaceous gland and duct within a hair follicle in a 21-year-old male with persistent acneiform eruption.

This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.

In this study, CD44 expression was absent in alopecia areata-affected scalp, with some patients regaining expression after treatment despite no significant hair regrowth, suggesting involvement in the disease's pathogenesis.

This review discusses the development of surgical hair restoration techniques and highlights the potential of hair follicle cell cloning to address current limitations.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

This study found that the p63 transcription factor is expressed during rat epidermal development and may serve as a specific marker for keratinocyte progenitor cells.

This review discusses the hormonal influences on acne's development in women and the therapeutic potential of hormonal treatments, but it reports no new clinical results.

This study found that reducing testosterone levels in male mice accelerates wound healing and decreases inflammation, suggesting a potential therapeutic target for improving wound repair in elderly males.

This study found that cutaneous pyridoxal 5'-phosphate hydrolase activity may be carried out by an enzyme different from the classical tissue-nonspecific alkaline phosphatase in human and mouse skin.

This study found that in obese mice, local antimicrobial activity is reduced due to a loss of adipogenic stem cells and an increase in mature adipocytes, leading to higher susceptibility to skin infections.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This study found that shorter CAG-repeat lengths in the androgen receptor may be associated with the development of androgen-mediated skin disorders like androgenetic alopecia, acne, and hirsutism in both men and women.

This review discusses how androgens may regulate wound healing and inflammation, noting that testosterone appears to inhibit healing and promote inflammation, but it reports no new clinical results.

This review outlines dermatological toxicities associated with targeted cancer therapies and immunotherapies, emphasizing the need for collaborative management by oncologists and dermatologists but reports no new clinical findings.

This study observed that 71% of chronic myeloid leukemia patients treated with second-generation tyrosine kinase inhibitors experienced adverse cutaneous reactions, which were generally less severe than those caused by imatinib.

In this study, topical application of α-methylspermidine during the telogen phase in mice induced hair growth by increasing the polyamine pool and mimicking the anagen phase's characteristics.

In this study, subcutaneous recombinant human IL-12 showed a 43% partial response rate in early-stage mycosis fungoides patients refractory to previous treatments, with generally mild to moderate adverse events reported.

This case report describes a patient with primary cutaneous natural killer/T-cell lymphoma, nasal type, where monoclonal Epstein–Barr virus genome expansion was associated with terminal aggressive behavior after an indolent clinical course.

The researchers concluded that hairless dogs can serve as an effective model for studying hypertrophic scarring due to their development of scars with morphological similarities to human hypertrophic scars.

This study found that patients with thyroid dysfunction were more likely to experience skin disorders such as chronic idiopathic urticaria, vitiligo, and alopecia areata compared to a control group.

This case report describes a hybrid cyst in a Sprague-Dawley rat, showing both infundibular and matrical differentiation similar to different parts of normal hair follicles.

This study observed that the small molecules KY19382 and KY19334 inhibited cancerous traits in human cutaneous squamous cell carcinoma cells by suppressing the Wnt/β-catenin pathway, indicating their potential as treatments for cancers involving CDK1 overexpression and diseases related to CXXC5 accumulation.

In this study, mouse sebaceous glands were found to require nerves for growth during active hair cycles, suggesting a nerve-dependent sebaceous gland cycle coordinated with hair growth.

This study concluded that a new model of reconstructed human epidermis using keratinocytes from plucked hair follicles offers a less-invasive alternative to conventional skin-derived models for skin research.
