Platelet-rich fibrin speeds up burn wound healing in rabbits.

This study observed that in Assam Hill Goats, the primary hair follicles had larger diameters and more structural associations compared to secondary follicles, especially in ruminant-age groups.

This article describes various hair and scalp examination techniques, including noninvasive, semi-invasive, and invasive methods, noting that trichoscopy is a simple, well-accepted, noninvasive technique for evaluating hair loss patients and monitoring treatment.

This study found that sulfated CCK octapeptide reduces psoriasis-like skin inflammation in mice, suggesting a new pathophysiological role for CCK in regulating epidermal inflammation.

In this study, HPH-15, a newly synthesized compound, demonstrated potential in reducing skin fibrosis in a mouse model by targeting underlying pathogenic mechanisms and exhibited a good safety profile, warranting further clinical trials for fibrotic skin disorders like systemic sclerosis.

In this study, deep phenotyping of 68 patients with XPD gene defects successfully separated individuals by clinical diagnosis and survival status, potentially improving diagnosis and prognosis for xeroderma pigmentosum and trichothiodystrophy.

Terbinafine is more effective than itraconazole for toenail fungus, especially in older patients, and debridement improves its effectiveness.

This study highlights the importance of understanding the rheological properties of hyaluronic acid fillers, including viscosity, cross-linking, and concentration, to optimize their use in addressing facial aging by maximizing clinical effects.

This review suggests that platelet-rich plasma therapy shows promise for androgenetic alopecia and may be effective for some alopecia areata and cicatricial alopecia cases, but more robust trials are needed.

This study found that Avicennia marina extract and its active compound avicequinone C inhibit enzymes and receptors related to androgenic alopecia, potentially supporting hair growth in cultured dermal papilla cells.

In this study, higher plasma leptin levels were associated with increased risk and severity of androgenetic alopecia in men, but further research is needed to understand the clinical implications.

This study reports the first instance of skin autotomy in mammals, specifically in African spiny mice, and suggests they may possess a greater regenerative capacity than previously understood, possibly offering insights for regenerative medicine.

This study found that low fluence photoepilation with intense pulsed light targets the pigmented area of hair follicles, causing temporary hair loss by inducing a catagen-like state without severe follicle damage.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

In this study, co-grafting human keratinocytes with murine dermal papilla-enriched cells produced hair follicle-like structures, but without regular hair formation, suggesting anomalous folliculogenesis.

This study found that human skin expresses proenkephalin, whose expression is upregulated by environmental stress and varies in pathological conditions, increasing in psoriasis and decreasing in melanocytic tumors.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.

This study demonstrated that cultured human dermal papilla cells can induce full hair follicle formation when combined with neonatal foreskin keratinocytes in a grafted dermal-epidermal construct on mice.

This study demonstrated that OSA hydrogels enhanced the stability and retention of dermal papilla-derived extracellular vesicles, which significantly improved hair regeneration in both cultured human hair and a mouse depilation model.

This study found that a 3D Matrigel culture technique for dermal papilla cell spheroids can enhance hair follicle inductivity and induce hair-like fiber differentiation in vitro, even with high-passage cells.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

This article reviews the role of vasoactive intestinal peptide in maintaining immune privilege in hair follicles and does not report new findings; the authors propose it as essential for immune homeostasis in alopecia areata.

This study found that the dermal papilla of the hair follicle regulates stem cell quiescence and regeneration by modulating Shh and Wnt signaling pathways, highlighting the importance of signaling cross talk in regeneration.

This review discusses recent advances in the role of dermal papilla cells and adipocyte lineage cells in hair regeneration, but it reports no new clinical results.

Skin cells can help create early hair-like structures in lab cultures.

This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

This study found that bovine lactoferrin promotes hair growth in mice by enhancing dermal papilla cell proliferation through the Erk/Akt and Wnt signaling pathways.

This study suggests that vitamin D-upregulated protein 1 (VDUP1) might play a unique role in regulating the differentiation of epidermal cells.
