Different lab conditions and light treatment methods change how human skin cells respond to light therapy.

This study found that radiofrequency treatment, with or without hydrolyzed collagen, increased dermis thickness, neocollagenesis, and FGF2 overexpression in rat skin tissue.

This study found that among Chinese males with male androgenic alopecia, combination therapy using topical minoxidil and nano-microneedle-assisted fibroblast growth factor significantly improved hair density, diameter, and follicular unit density over 16 weeks, outperforming individual treatments.

In this study, significant improvements in skin density and thickness, especially around the lower eyelid, were observed across all age groups using plasma fractions from a single blood draw, indicating that the therapy's effectiveness may be age-independent.

In this study, researchers discovered that fat grafting helps reduce dermal fibrosis in radiation-injured mouse skin by decreasing specific fibroblast subpopulations associated with Fra/c-Jun signaling.

This study found that applying a growth factor cocktail including FGF9 with microneedling significantly increased hair density and diameter in patients with androgenetic alopecia, with similar results regardless of microneedle depths between 0.5 mm and 0.8 mm.

This study found that iontophoresis with growth factor cocktail including fibroblast growth factor 5-short significantly increased hair density in patients with androgenetic alopecia over 24 weeks.

This study investigated the effects of GFC with FGF5s and NMN at a depth of 0.8 mm using a microneedle for treating hair loss, but the abstract provides no measurable results.

A treatment called Cellcurin, combined with microneedling, significantly increased hair density and diameter in patients with hair loss.

This study demonstrated that human hair follicle stem cells can be efficiently differentiated into endothelial-like cells using VEGF and bFGF, suggesting their potential as a novel cell source for vascular tissue engineering.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This review examines the complexities of age-related skin healing and discusses how translating findings from model organisms to humans could enhance understanding and treatment of impaired regeneration in aging populations, but it reports no new clinical results.

This review explores the cellular and molecular basis of wound-induced hair neogenesis and its relationship with aging but does not report new clinical results, highlighting areas for future research.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.

This study found that the combination of L. sericata secretions and A. sintenisii extract significantly enhanced wound healing compared to each agent alone or Furacin®, suggesting a synergistic effect.

This study found that stem cells from the human umbilical cord's Wharton's jelly may significantly enhance healing in excisional and diabetic wounds compared to controls.

This review explores the role of macrophage subsets in adult cutaneous wound healing and emphasizes their potential for therapeutic targeting, but reports no new experimental results.

Injecting platelet-rich plasma (PRP) can increase hair growth rate and density in male pattern baldness.

This study suggests that controlling light exposure can influence cashmere growth by triggering hair follicles to enter their active growth phase sooner, potentially involving the CSDC2 gene as a key regulator.

This study generated a gene-edited cashmere goat with improved cashmere yield and fiber length by integrating VEGF at the FGF5 site, offering insights into hair growth mechanisms.

This review discusses various theories of skin aging and the importance of using professional and at-home skincare solutions, but offers no new empirical findings.

In this mouse study, researchers reported that sequential monopolar-bipolar radiofrequency irradiation significantly improved skin quality by increasing collagen density, elastin fiber expression, and fibroblast differentiation more than monopolar RF treatment alone.

In laboratory studies on mice, Abstract UT-018, a stem cell chemoattractant formulation, was reported to significantly enhance wound healing and promote hair regeneration through mechanisms involving improved tissue formation, collagen organization, and follicular development.

This study reported that newly developed RADA16-I peptide hybrids, with active motifs like GHK and KGHK, demonstrated improved wound healing in a mouse skin injury model without cytotoxicity, suggesting they might be effective scaffolds for tissue engineering and regeneration.

In this exploratory randomized controlled trial, participants using a combination of Centella asiatica-derived extracellular vesicles with recombinant growth factors showed significant improvements in hair thickness, density, length, and reduced hair loss and scalp sebum content after 56 days, compared to placebo.

In this study, the use of rb‐bFGF in hair transplantation significantly increased follicle survival, reduced hair loss, improved patient satisfaction, and decreased complications compared to controls, in patients with androgenetic alopecia over a 12-month period.

In this study, the researchers found that the water-soluble fraction of Rhus semialata gall extract and its component Penta-O-Galloyl-β-D-Glucose promoted hair growth in human dermal papilla cells, and clinical trials supported these findings, showing improved hair density and appearance compared to placebo.

This study suggests that high platelet concentrations in PRP may not be necessary for hair growth in androgenetic alopecia, and certain growth factors might negatively impact clinical outcomes.

This study concluded that TrichoxidilTM positively affected hair growth by increasing growth factor expression and fibroblast proliferation, suggesting it may be a promising treatment for androgenetic alopecia.

In this study, FGF5-knockout Dorper sheep generated using CRISPR/Cas9 showed increased fine-wool and active hair-follicle density, suggesting potential therapeutic applications for androgen alopecia.
