In a transgenic mouse model, this study found that overexpression of keratin 16 in skin keratinocytes led to hyperkeratosis and increased EGF receptor signaling, altering skin cell behavior and structure.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

This study found that β-catenin signaling increases in newly born glial cells in the cortex after traumatic brain injury in mice, suggesting potential targets for enhancing recovery through the Wnt/β-catenin pathway.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This study suggests that finasteride may be a promising treatment for chronic central serous chorioretinopathy, but larger controlled trials are needed to confirm its efficacy.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

This study found that oxidative damage is present in the mitochondria of PolG mice, which exhibit premature aging-like phenotypes due to mitochondrial dysfunction.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This study found that Arabidopsis mutants with disrupted auxin conversion pathways displayed low auxin phenotypes and increased biosynthetic gene expression, suggesting a feedback mechanism maintains auxin homeostasis.

This study found that FGF-9 treatment in diabetic mice improved heart function after myocardial infarction by decreasing monocyte infiltration and promoting anti-inflammatory macrophage differentiation.

This study suggests that heparan sulfate is crucial for regulating hair follicle formation, cycling, and gland morphogenesis, with its ablation leading to continuous hair growth and increased gland activity in mice.

This study found that white hair exhibits increased expression of genes and proteins linked to active hair growth compared to black hair, suggesting that hair greying is associated with enhanced hair growth activity.

This study extended a skin diffusion model to include a porous pathway, effectively explaining the permeability of both polar and lipophilic solutes through the stratum corneum.

This study demonstrates that dermal white adipose tissue regulates human hair growth and pigmentation through hepatocyte growth factor secretion, highlighting potential therapeutic targets for hair-related disorders.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study established a mouse model for Cushing's syndrome due to a specific Crh mutation, which may help explore the effects of glucocorticoid excess and evaluate treatments for corticosteroid-induced osteoporosis.

This review discusses recent advances in developmental tissue engineering for regenerating ectodermal appendages like teeth and glands, emphasizing biomaterial selection and cell culture strategies, but reports no new experimental results.

This study observed that between 2000 and 2004, males underwent fewer aesthetic facial procedures than females, except for hair restoration and otoplasty, with a trend toward more nonsurgical requests over time.

This study demonstrated that dermal papilla cells are molecularly distinct from fibroblasts and identified many novel molecules, including a new member of the CTGF protein family.

In this paper, the authors provide recommendations for primary care practitioners on evaluating and treating pediatric hair loss, emphasizing the importance of early diagnosis to prevent permanent scarring alopecia by classifying causes into acquired or congenital origins.

This study found that keratin intermediate filaments in the hair of GAN patients are altered, showing decreased diffraction signals and increased stiffness, strength, and extensibility.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

The guideline provides healthcare professionals in South Africa with instructions for comprehensive, multidisciplinary gender-affirming care, including HIV prevention and treatment for transgender and gender diverse individuals.

In this study, HYDRO DELUXE BIO was reported to show promise for scalp mesotherapy by enhancing angiogenesis and reducing inflammation in an in vitro model.

This study demonstrated that both classical and atypical BSE strains from cattle can be transmitted to goats, highlighting the importance of surveillance in protecting public health.

This review discusses the potential use of spin traps in cosmetic products to limit reactive oxygen species generated by pollution, emphasizing the need for further research due to toxicity and regulatory concerns.

This study found that specialized nipple epidermis in mice is maintained by the repression of TGFβ signaling through estrogen, which highlights the role of hormonal regulation in epidermal maintenance.

This study found that heat preconditioning of nanofat from mice did not improve tissue vascularization or integration in grafting, and actually reduced vascularization due to increased expression of anti-angiogenic factors, suggesting it is not beneficial for enhancing its vascularization properties.

This study found that multiple treatments combining NIR laser phototherapy with ICG significantly reduced inflammation and improved skin condition in acne without side effects.
