This review examines how caloric restriction could promote autophagy to rejuvenate aging stem cells, though the precise molecular mechanisms remain unclear.

This study developed and tested a new injectable hydrogel for chronic diabetic wounds, reporting significant improvements in wound healing through enhanced angiogenesis, epithelization, and reduction of inflammation and infection in animal models.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

This review highlights the potential of microneedles for immunotherapy, emphasizing their ability to enhance immune responses and reduce side effects through precise and stimuli-responsive delivery, especially in tumor treatment, while also noting the limitations and areas for improvement in current systems.

This study found that elevated epidermal ODC activity in transgenic mice promotes skin tumor development by recruiting bulge stem cells, rather than through reactive oxygen species generation by polyamine catabolic oxidases.

This article reviews the impact of H2O2-redox homeostasis on hair follicle pigmentation via tyrosinase and associated mechanisms, discussing primarily findings from murine models without providing new clinical results for humans.

This study suggests that iron influences auxin signaling through vesicle trafficking, particularly affecting PIN2 recycling, which may play a role in phosphate starvation-induced root hair growth in Arabidopsis.

This study found that minoxidil stimulates the Kir6.2/SUR2 potassium channel, leading to tumor growth arrest in an ovarian cancer xenograft model by disrupting mitochondrial function and inducing cell death.

This study proposes a model describing the transformation process from living to dead cells during early hair formation, highlighting the stepwise degradation of cellular functions.

This study suggests that epigallocatechin gallate (EGCG) from green tea may counteract DHT-induced hair follicle damage by modifying the miRNA expression profile in human dermal papilla cells.

This study found that puerarin, derived from Pueraria thunbergiana, may stimulate melanogenesis and prevent follicular depigmentation in a hair graying mouse model.

This study found that glycolysis in Paneth cells provides lactate to support mitochondrial oxidative phosphorylation in intestinal stem cells, aiding their function and differentiation.

This study found that S-Methylmethionine sulfonium (SMMS) enhances cell survival and reduces damage from UVB irradiation in skin cells, suggesting its potential as a cosmetic ingredient for UV protection.

This study found that dermal stem cells from granulation tissue promoted wound healing and reduced fibrosis in a combined radiation and skin wound mouse model.

This case report describes a child with hypopigmented mycosis fungoides successfully treated with UVA1 light therapy.

This study found that high-resolution laser speckle contrast imaging devices provide good reproducibility for assessing skin perfusion in mice but not for measuring haemoglobin oxygenation.

In this study on rat dermal papilla cells, hydroxytyrosol, an antioxidant found in olive oil, was reported to protect against oxidative stress, reduce inflammation, and enhance hair growth factors, suggesting its potential to prevent hair loss.

This study found that the spermidine analog N1-methylspermidine prolonged hair follicle growth and decreased inflammation and oxidative stress in cultured hair follicles, suggesting potential relevance for treating inflammatory scalp diseases.

This study found that semagenesis, involving benzoquinone signaling, impacts root development in both parasitic and non-parasitic plants and suggests potential strategies for managing parasitic angiosperms in agriculture.

This study found that PBX1 overexpression reduces hair follicle-derived mesenchymal stem cell senescence and apoptosis by interacting with SIRT1 and PARP1, highlighting a potential mechanism for addressing aging-related diseases.

This review explores the factors contributing to premature graying of hair, highlighting the role of genetic and environmental influences such as oxidative stress, and discusses potential interventions like diet and herbal remedies, while noting the limitations of common treatments like hair dyes.
