Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

In this case report, a 49-year-old heavy smoker experienced scalp necrosis after hair transplantation, but wound closure was achieved within two weeks using a treatment combining topical agents and photobiomodulation; the potential role of photobiomodulation needs further study.

This case report describes a 29-year-old Japanese man with follicular mucinosis, suggesting nestin-positive, multipotent hair follicle stem cells may be involved in reticular epithelial degeneration of the outer root sheath.

This study describes a method for serially cultivating adult human hair follicle keratinocytes using a specific growth substrate and cryogenic storage, enabling subculture and immunofluorescence studies.

This study developed in vitro methods to regenerate hair follicles and erector muscles by mimicking their native structures and mechanical conditions, reconstructing hair follicle-like structures and forming muscle-like tissues.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study found that in adult mouse skin, reduced levels of histone H3 K4/K9/K27me3 during hair follicle stem cell quiescence are linked to proper tissue homeostasis.

This study found that adrenal hormones appear to inhibit winter fur growth onset in mink and may affect the duration of inactivity between fur growth periods.

This review discusses the unique capacity of fetal skin to heal wounds without scarring and notes that while many factors have been identified, the complete mechanism of fetal wound healing remains unclear.

This study observed that in mouse fetuses, reticular contraction by actomyosin is involved in dermal regeneration, and differences in actin and α-SMA localization may determine the switch between regeneration and scar formation, suggesting potential insights for wound regeneration therapy.

This article reviews the concept of caloric restriction and its potential anti-aging effects, highlighting animal studies and a human experiment in Biosphere II, but notes significant challenges for its application in humans.

This study is the first to document significant age-related pathologies in endangered captive Julia Creek dunnarts, highlighting hormonal dysregulation and reproductive issues in females, while males exhibited higher occurrences of cutaneous diseases and testicular degeneration, providing valuable insight for conservation efforts.

This study found that human epidermal stem cells can adapt to small temperature variations via mTOR signaling, and that prolonged mTORC1 inhibition supports stem cell maintenance.

This study found that prevascularizing dermal matrices with adipose tissue-derived microvascular fragments improved vascularization and allowed earlier successful skin grafting in a bradythrophic wound model.

This study investigated the mechanism responsible for pili torti formation in Björnstad syndrome using a transmission electron microscope, but did not establish a definitive explanation.

This study found that the protein p63 requires morphogenetic signals to regulate gene expression effectively during skin cell differentiation, highlighting its complex role in therapeutic reprogramming for conditions like epidermolysis bullosa.

This case report describes an ossifying pilomatrixoma found in a 15-year-old girl, confirmed via histopathological examination after imaging indicated a subcutaneous mass on her cheek.

In this study, the researchers found that tyndallization effectively sterilizes aqueous solutions of hyaluronic acid without diminishing their regenerative properties, and these properties remain intact even at low temperatures, supporting potential applications in cryobiology and cryomedicine.

In this study, an Emulgel containing Tridax procumbens extract was formulated and found to have promising physical properties and antimicrobial activity for wound healing.

This study developed a bilayer bionic skin scaffold that mimics the skin's structure to resist microbial invasion and enhance wound healing, with in vivo animal studies showing improved collagen deposition, neovascularization, and hair follicle formation.

This study found that steroid reproductive hormones such as estradiol and testosterone can be preserved and analyzed in archaeological human hair, providing new insights into ancient health and fertility.

Methylmercury accumulates in mouse hair during growth, then decreases when growth stops.

The study concluded that fatty acid transport protein 4 in epidermal keratinocytes is crucial for maintaining normal skin structure, as its deficiency led to hyperkeratosis and epidermal barrier disruption in mice.

This article describes the Dermatologic Surgery journal's coverage of a wide range of skin surgery topics but reports no new research findings.

This abstract discusses the potential link between unexplained infant crying and tourniquet syndrome, noting the importance of considering underlying causes such as abuse, but reports no new clinical findings.

This study successfully developed a reproducible mouse model demonstrating fetal scarless wound healing, which may provide insights for minimizing scarring in adults.

This study found that incorporating Musa extracts in pretreatment products effectively mitigated hair damage during permanent wave application, closely maintaining hair thickness and tensile strength compared to untreated hair.

This study found that Mf-rich-fiber in human hair underwent significantly greater degradation by proteases than Ma-rich-fiber, especially when treated with Proteinase K.

This case report highlights a rare presentation of hair-thread tourniquet syndrome in a two-year-old child, emphasizing that prompt identification and removal of the constricting fiber is crucial for successful treatment and prevention of tissue damage.

This study found that deep plane fixation in scalp surgeries allowed for tension-reduced wound closures and increased tissue excision compared to techniques without deep plane fixation.
