The research also examined challenges like biocompatibility and regulatory requirements on the path to clinical use.

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 study found that disrupting Sox21 in developing teeth leads to severe enamel hypoplasia, regional osteoporosis, and abnormal hair formation, with impaired dental epithelial differentiation and regulation of hair follicle cell fate.

This review explores the structural and functional sex differences in mammals beyond reproductive organs, highlighting variations in life expectancy, organ size, metabolism, and immune function, but it reports no new results.

This review discusses the effects of neuroactive testosterone metabolites on CNS functions and suggests their potential as therapeutic options for neurological disorders, but reports no new clinical results.

This study found that an aqueous extract of Bacopa procumbens improved motor function and preserved neuronal structure in a mouse model of Parkinson's disease, suggesting its neuroprotective potential.

This review compiles evidence indicating that rosemary essential oil may enhance cognitive function, sleep quality, mood, and pain management in aromatherapy; however, it also notes potential allergic reactions, emphasizing caution in its use.

This article reviews evidence suggesting that vitamin D may help manage Hashimoto’s thyroiditis by affecting immune pathways and improving thyroid function, though more research is needed to fully understand its therapeutic potential.

This abstract provides a comprehensive overview of enzyme classification, function, and interaction with drugs, but does not present new research findings.

This study found that Cannabidivarin (CBDV) promotes neuronal differentiation and inhibits oligodendrocyte maturation via TRPV1 modulation, highlighting its potential in neural stem cell research.

In this study, chick embryo extract enhanced neuronal differentiation and trophic factor expression in rat hair follicle stem cells, suggesting potential improvements for stem cell therapies in neurodegenerative diseases.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

In this study, researchers linked SARS-CoV-2 infection to telogen effluvium in some COVID-19 patients by observing the accumulation of viral proteins in hair follicle cells, which may trigger stress responses and cell death, suggesting hair follicles as a potential target in COVID-19.

This study found that vinegar-processed black soybean and its extract accelerated hair growth and prevented alopecia in mice, with potential mechanisms involving modulation of the Wnt/β-catenin signaling pathway, suggesting they may be promising functional foods for hair regeneration.

This study found that systemic ovalbumin–aluminum sensitization followed by cutaneous challenge in mice induced thermal hyperalgesia, increased spinal cord gliosis, and sprouting of nociceptive fibers, along with elevated mast cell and nerve profile densities in the skin compared to controls.
