In this study, researchers developed gellan gum hydrogels functionalized with biomimetic peptides that create a supportive microenvironment for human dermal papilla cells, enhancing their hair-inductive capacity and ability to mimic hair morphogenesis-like events in vitro.

This study identified a unique transcriptional signature in occipital hair follicles that may protect them from miniaturization in androgenetic alopecia, using an animal-free model to investigate gene roles.

This study found that a titrated extract of Centella asiatica enhanced the hair growth potential of 3D spheroid cultured human dermal papilla cells.

Veratric Acid may help promote hair growth and reduce hair loss.

This study found that the natural estrogen Estetrol (E4) may promote hair follicle growth and prevent miniaturization, suggesting its potential as a treatment for hair loss disorders.

This review discusses the potential of organoids in modeling COVID-19 disease and developing therapies, without reporting new results, and highlights opportunities and challenges in their application for research.

This study suggests that interfollicular epidermal keratinocytes with stem-like features may serve as an alternative to follicular keratinocytes for hair regeneration by supporting hair follicle morphogenesis in vivo.

In this study, injectable platelet-rich fibrin (i-PRF) was found to enhance the proliferative, migratory, and hair-inducing abilities of dermal papilla cells more effectively than platelet-rich plasma through the TGF-β/Smad pathway.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

Hair growth is influenced by factors like genetics and nutrition, and more research is needed to understand hair loss and growth mechanisms.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This review discusses the potential of cell-derived nanovesicles as innovative treatment strategies for hair growth and provides no new clinical results; the authors emphasize the need for further understanding of their mechanisms.

This study found that inhibiting class I histone deacetylases in postnatal mouse dermal cells preserved their ability to induce hair follicles during culture by increasing specific gene expressions and activating the Wnt signaling pathway.

This review discusses advanced techniques for investigating stem cell fate at the single-cell level, including lineage tracing, time-lapse imaging, and molecular profiling, but reports no new research results.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This review discusses how circadian clocks may influence diverse physiological functions beyond their established role in daily timekeeping, but it reports no new experimental findings.

This review discusses recent advances in hair follicle biology, regeneration, and tissue engineering, highlighting emerging therapeutic opportunities, and reports no new experimental results.

This study found that DKK1 and WNT10b are paracrine factors that modulate hair follicle stem cell differentiation inhibition, contributing to androgenetic alopecia by affecting Wnt signaling in androgen-sensitive dermal papilla cells after dihydrotestosterone stimulation.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This study found that adipose-derived stem cell exosomes promoted hair follicle regeneration in mice, resulting in a higher number of regenerated hairs and follicles compared to the control group.
