This review explores the similarities between wound healing, palatogenesis, and orofacial clefting, suggesting these processes share common pathways and genetic regulatory mechanisms, but reports no new experimental results.

This review indicates that while microneedling shows potential for managing androgenetic alopecia, particularly in combination with other treatments, the existing evidence is of low to moderate quality, and more robust trials are needed to confirm its clinical efficacy and safety.

This review outlines the potential of using human pluripotent stem cells for hair follicle bioengineering, detailing current HF morphogenesis and cycling knowledge, various cell sources, and strategies using iPSCs, while discussing the challenges and prospects for therapeutic use in addressing hair loss.

This review outlines recent advances in stem cell and tissue engineering technologies in regenerative medicine and wildlife conservation, reporting no new clinical results.

This review examines current treatments and the potential role of stem cells in cutaneous wound healing, but it presents no new clinical results and calls for more research on mechanisms.

This study found that both genome-wide screening methods identified the VTRNA2-1 epiallele as highly responsive to environmental influences, suggesting a link between early embryonic environment, epigenetic changes, and human disease.

This study found that absence of the vitamin D receptor in keratinocytes impairs canonical Wnt signaling and leads to alopecia due to defects in keratinocyte stem cells.

This review discusses the effects of hormonal changes on hair follicles, concluding that hormones like androgens and estradiol significantly influence hair growth and cycle, while the roles of other hormones are still being researched.

Protein ubiquitylation is crucial for controlling stem cell functions and could be targeted for cancer treatment.

This position paper from the Italian Mesotherapy Society discusses the application of intradermal therapy based on scientific evidence, highlighting its potential benefits for certain localized conditions, although it acknowledges the lack of randomized clinical trials for some uses.

This study investigated dermal fibroblasts in mouse skin using single-cell RNA sequencing and identified signaling pathways that influence adipogenesis, finding that IL-1-NF-κB promotes, while WNT-β-catenin inhibits, the adipogenic potential of these cells, with implications for wound healing and scar formation.

This study found that combining a human acellular amniotic membrane with iPSC-derived epithelial stem cells effectively repaired skin defects and promoted hair follicle formation in nude mice.

This review discusses the current state of research on skin organoids, highlighting their potential for replicating complex skin structures and comparing recent studies on stem cell microenvironments.

This review discusses methods for generating induced pluripotent stem cells and highlights their recent applications in studying and treating COVID-19, but it reports no new experimental results.

In this study, using stirred-suspension bioreactors to expand dermal stem cells resulted in larger numbers, but had reduced efficiency in forming hair follicle structures compared to static culture conditions.

This narrative review explores the molecular mechanisms driving skin development and their role in skin diseases, emphasizing how disruptions in these pathways can lead to conditions like congenital disorders and cancers, potentially guiding new targeted therapies.

This review discusses the role of telomere length dynamics in hair follicle biology and reports no new clinical findings, emphasizing the need for further research in humans.

In this study, researchers found that while both hair follicles and skin dermis-derived neural crest stem cells are suitable for large-scale manufacturing, skin dermis cells grow faster and are easier to obtain.

This study found that Sox2 within dermal papilla cells in the hair follicle regulates hair pigmentation, influencing the type and production of melanin.

This study demonstrated that dermal papilla cells were more efficiently reprogrammed into induced pluripotent stem cells than dermal fibroblasts, suggesting their potential as a source for iPS cells.

This study found variable outcomes in hair loss treatment with autologous cell-based therapy using DSC cells, with certain gene markers showing inconsistent correlations with treatment efficacy.

In this study, maternal exposure to constant light significantly altered the neonatal skin structure in rabbits, associated with reduced maternal melatonin levels.

This study found that retinoic acid induces epidermal transdifferentiation into mucosal epithelium in both chick and mammalian embryonic skin, involving specific gene expressions and pathways.

This study found that plucked hair follicles can serve as a practical and scalable source for regenerative medicine, as researchers successfully isolated and expanded keratinocytes and mesenchymal stem cells for potential cell-based and cell-free therapies, demonstrating significant wound-healing bioactivity in vitro.

This review examines experimental studies on using platelet-rich plasma, stem cells, or a combo with surgical meshes for hernia repair, but presents no new results; it highlights regenerative medicine's potential in this area.

This study reviews advancements in hair follicle regeneration, discussing the benefits and limitations of methods such as organ germ assembling, stem cell induction, and bioprinting, while highlighting the challenges of replicating embryonic signals and finding suitable cell sources for clinical applications.

This systematic review found that both cellular and acellular stem cell-based therapies are safe and able to improve hair regeneration and density in patients with androgenic alopecia, although some results may be temporary.

This review compares mesotherapy and PRP for hair loss but reports no new clinical results; the authors highlight the need to understand their differences for optimal treatment choices.

This case report found that the most likely cause of the patient's seizures and brain tumor was prior radiation exposure, with seizures managed effectively using intravenous lorazepam and subsequent treatment for the brain mass.

This study observed that overexpression of TGF-alpha in transgenic mice led to thicker epidermis and stunted hair growth, particularly in regions with normally thick skin and low hair density.
