This study found that Wnt7a protein expression increased after corneal epithelial injury and promoted human corneal epithelium cell proliferation by upregulating fibronectin and enhancing cell adhesion.

In this study, the researchers shared their experiences with using local intracanal antibiotic therapy for treating endodontic bacterial infections, noting that current disinfectants, though effective, are highly toxic to human cells.

In this study of Angora goats, researchers found that HOXC13 and other genes were overexpressed during the active hair growth phase, suggesting a role in mohair structure.

This study found that inducing miR-205 reduces actin contractility and stiffness in hair follicle stem cells and progenitors, stimulating hair regeneration in both young and old mice.

This study found that HOXC13 gene expression was significantly higher during the anagen phase in Angora goats, potentially contributing to the mohair's shiny and silky nature.

This study found that mammary resident macrophages regulate mammary epithelium cell division and development, with implications for maintaining mammary stem cell activity and homeostasis.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.

This study found that overexpression of the SbbHLH85 gene in sweet sorghum increases root hair growth and Na+ absorption, but negatively affects salt tolerance.

This study found that the HoxC gene cluster is crucial for the development of hair and nails in mice, with key regulation by two mammalian-specific enhancers.

In this animal study, the researchers found that DPP4 plays a crucial role in scar formation and wound-induced hair follicle neogenesis in mice, impacting regenerative repair.

This study found that testosterone and dihydrotestosterone can induce growth factors from dermal fibroblasts, promoting keratinocyte proliferation and differentiation, which may contribute to sex hormone-related acne development.

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 special issue contains abstracts from the ASA 40th Annual Meeting, providing an overview of various studies without reporting new primary results.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This review discusses the traditional uses and pharmacological properties of Hedychium spicatum, noting that while some traditional uses are supported by scientific studies, further research on its applications is needed.

This study found that COVID-19 infection disrupts spermatogenesis, alters testicular cell populations, and may impact male fertility by causing long-term changes in testicular function and reduced sperm quality, as observed even in patients who have recovered from the acute phase of the infection.

This review integrates studies on mouse models and human clinical observations to highlight the role of immune cells in skin development and how their dysregulation leads to skin disorders, suggesting potential therapeutic pathways for skin regeneration.

In this study, researchers found that CD4 T cells from the skin draining lymph nodes of mice with alopecia areata can transfer the disease to recipient mice, highlighting the key role of these cells and their interaction with CD8 T cells in the disease's development.

This review explores the potential impact of SARS-CoV-2 on benign prostatic hyperplasia and related lower urinary tract symptoms but reports no new clinical results, emphasizing the need for further studies to quantify these changes.

This case study from Ukraine describes a 5-year-old Akita dog diagnosed with sebaceous adenitis, presenting with pruritus, alopecia, and inflammation; treatment over 30 days led to complete restoration of affected areas, implicating potential heritability in Akitas.

This review highlights that COVID-19, beyond affecting the respiratory system, leads to various complications across multiple organ systems like cardiovascular, neurological, and immune, emphasizing the importance of understanding these to enhance patient care and guide future research.

In this mouse study, the absence of the Ascl4 gene did not affect the development of hair follicles, teeth, or mammary glands, suggesting it is non-essential for these processes.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study found that treatment with Bacillus amyloliquefaciens UCMB5113 significantly increased root hair growth in half of the tested Arabidopsis thaliana accessions.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.

In this study, a pH-responsive microneedle patch was developed, showing potential in rat models for treating spinal cord injuries by reducing inflammation, promoting nerve regeneration, and supporting neurogenesis, which contributed to improved motor and neurological recovery.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This study reports that a new mouse model with a CARD14 mutation successfully mimics key human PRP symptoms, and anti-IL-17A antibody significantly reduces these symptoms.

This study found that hair follicles in mice and humans can convert wound-related myofibroblasts into adipocytes, suggesting a potential pathway to reduce scar formation by activating BMP signaling.
