This study found that cefazolin-loaded silica nanoparticles embedded in polycaprolactone nanofibers successfully inhibited Staphylococcus aureus growth while maintaining stem cell viability, suggesting their potential use in wound healing.

This study reports that mesenchymal stem cell-conditioned medium promoted dermal cell migration and proliferation, enhancing wound healing but not direct hair growth, in vitro and in adult mouse models.

This study suggests that policosanol may prevent androgenetic alopecia in mice by regulating hormone levels and suppressing premature hair follicle entry into the regression phase.

This study found that adding platelet-rich plasma with microneedling to conventional medical treatment significantly increased hair density and diameter in androgenetic alopecia patients compared to medical treatment alone.

This study reports that the side population technique can isolate melanocyte stem cells from human hair follicles, potentially allowing them to be used for skin pigmentation repopulation.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

In this study, transplantation of rat hair follicle stem cells significantly improved sciatic nerve regeneration and muscle function in nerve-injured rats.

This study found that platelet-rich plasma injections promote hair growth and are safe and effective for treating androgenetic alopecia.

In their research, Yucel and colleagues found that CaV1.2 is expressed in hair follicle stem cells, facilitating anagen re-entry in a way not dependent on calcium flux.

This review discusses current and potential approaches using stem cells for treating hypopigmentation disorders like vitiligo but does not present new clinical findings.

This review outlines recent advancements in understanding how micro-RNAs (miRNAs) influence hair regeneration, highlighting their role in stimulating hair growth and potential therapeutic approaches, while also addressing the challenges of clinical translation due to miRNAs' complex roles and delivery issues.

This review outlines the transition from simple hair follicle organoids to immune-competent microphysiological systems, addressing limitations in replicating native hair follicle immune features and discussing their applications in disease modeling and regenerative medicine.

In this study, researchers used single-cell RNA sequencing to map the hair follicle microenvironment in fine-wool sheep, identifying specific cell types and gene expressions that influence wool fiber diameter, with dermal papilla cells playing a significant role in hair follicle development.

This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.

This study observed that topical application of maslinic acid stimulated hair growth in mice comparably to minoxidil, possibly through the Wnt/β-catenin pathway and involving ciliary gene activity, highlighting increased levels of trichogenic gene expression and protein levels.

In this phase I/II clinical trial, placenta-derived mesenchymal stem cell exosome therapy significantly improved hair density and diameter, and reduced hair loss in patients with androgenetic alopecia, though further large-scale studies are needed to confirm these results and investigate the underlying molecular mechanisms.

This study found that new methods for isolating human dermal papilla cells were more efficient than traditional methods, maintaining higher levels of specific markers and improving the cells' research potential.

This study suggests that phloroglucinol may enhance anagen signaling and reduce oxidative stress-induced damage in human dermal papilla cells, offering a potential therapy for hair loss.

This study found that extracts from Cirsium japonicum var. spinossimum seeds are rich in polyphenols and flavonoids, demonstrating significant anti-inflammatory and cell proliferation effects in specific cell models, suggesting potential as a source for anti-inflammatory and anticancer agents.

In this study, researchers found that while applying a lotion containing Lactiplantibacillus plantarum subsp. plantarum N793 did not improve hair density overall compared to placebo, it was effective in improving hair density among individuals with relatively mild hair thinning.

This source reviews mechanisms and existing treatments for hair aging, highlighting factors like oxidative stress and DNA repair defects that affect hair follicle and stem cell function, and discusses research limitations and future directions in the field.

This study found that in mice, oral administration of Lactilactobacillus curvatus LB-P9 accelerated hair regrowth and increased hair thickness, hair follicle numbers, and dermal thickness, likely by boosting hair growth factor production and dermal papilla proliferation.

This study found that neonatal Regulatory T cells are crucial for maintaining PPARγ signaling in hair follicles, which supports melanocyte stem cell function and skin pigmentation during early postnatal development.

Targeted immunotherapy could be a promising new treatment for hair regrowth.

In this study, freezing gamma-irradiated amniotic fluid increased hair follicles and accelerated the transition to the anagen stage in rats, suggesting potential for treating hair loss safely and effectively.

This study presents evidence that hair matrix progenitors and the enzyme Stearoyl CoA Desaturase 1 may play a role in maintaining the dermal papilla niche via autocrine Wnt and paracrine Hedgehog signaling in mice.
