This review discusses the regenerative processes of lizard tails, particularly focusing on the diversity in blastema development across different species, and reports no new findings.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This study found that high levels of parathyroid hormone-related protein expression can result in the production of shorter hair shafts, likely through effects on angiogenesis.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

This study found that Wnt3a increased beta-catenin signaling and upregulated specific genes in cultured human dermal papilla cells, enhancing their response to PGE2 and potentially aiding hair growth.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This review covers recent developments in inner ear therapeutics and gene delivery methods but reports no new clinical results; it highlights potential strategies for treating hearing and balance disorders.

This study observed that selectively activating activin in the epidermis of mice enhanced reepithelialization during wound healing without altering the quality of the healed wound.

This study found that neonatal mice without the urokinase-type plasminogen activator (uPA) gene had reduced epidermal proliferation rates, suggesting uPA's involvement in promoting keratinocyte proliferation.

This study found similarities in the regeneration processes of MRL mouse ears and axolotl limbs, involving G2 cell cycle arrest and nerve-dependent mitosis, but the role of p21 in axolotl limb regeneration remains uncertain.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This study found that HPV16 oncogene expression in multipotent epithelial stem cells led to abnormal mobilization, altering their quiescence without affecting other stem cell markers, suggesting a distinct stem cell compartment.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

This practical guide introduces methods to study human dermal white adipose tissue but does not report new clinical results, emphasizing available techniques and staining protocols.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

This review summarizes recent progress in human hair follicle bulge cell research, particularly the characterization and isolation of these stem cells, but reports no new experimental results.

This study found that Wnt ligands from CD133-positive dermal papilla cells are essential for maintaining hair growth by supporting cell signaling between different hair follicle structures.

This review discusses the therapeutic properties of polydeoxyribonucleotides derived from marine organisms for wound healing and inflammation, but it reports no new clinical results.

This study found that quiescent bulge stem cells, when prevented from contributing to hair follicle and epidermal regeneration, did not affect hair follicle growth or wound healing in the short term.

This study identified a novel recessive mutation in mice causing lethal congenital lamellar ichthyosis, with skin and hair follicle alterations similar to human congenital ichthyoses, linked to a specific genetic defect affecting Fatp4.

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, researchers observed that quiescent mouse embryonic fibroblasts showed reduced glycolysis but increased TCA cycle flux and mitochondrial respiration, with these changes linked to metabolic reprogramming involving yes-associated protein inhibition and malate cycle modulation, which supports extracellular matrix protein synthesis.

This study found that β-catenin is essential for hair follicle stem cell proliferation and may regulate this process through the PI3K/Akt pathway, suggesting its potential as a therapeutic target.

This study identified FP-1 as a highly specific extracellular matrix protein in follicular papilla cells, which may play a role in hair growth regulation during specific hair cycle phases.

This study found that Pep-1-mediated mitochondrial transplantation was as effective as PRP therapy in restoring hair loss related to aging in mice, with distinct improvements in hair and skin-related measures.

This study found that Hedgehog signaling likely contributes to cervical carcinogenesis, and while itraconazole reduced growth in mice, it did so through pathways other than inhibiting Hedgehog signaling.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

In this study, beta-caryophyllene enhanced wound healing in female mice by improving re-epithelialization, cell proliferation, and cell migration, suggesting potential benefits of essential oil compounds in inflammation reduction.
