This study identified an optimal sulfate-free and silicone-free conditioning shampoo formulation using 1% hyaluronic acid at 800 kDa, 10% acidic sophorolipid, and 1% sodium chloride, which maintains essential conditioning and cleansing properties without compromising on performance.

The study found that over-expressing ornithine decarboxylase in the outer root sheath of the hair follicle in mice increases UVB-induced tumor growth and invasive squamous cell carcinoma compared to inter-follicular epidermal keratinocytes.

This study observed that cutaneous microwounds created by fractional photothermolysis heal differently from typical wounds, displaying rapid re-epithelialization and limited inflammation, which may help reduce scar formation by delaying collagen remodeling and minimizing myofibroblast activation.

This study found that a hypoxic microenvironment enhanced the proliferation and pluripotency of adipose mesenchymal stem cells, promoting hair follicle formation and upregulating specific growth factors in Arbas Cashmere goats.

This study suggests that a supercritical CO2 extract from wild-strawberry-processing waste may be an innovative and sustainable ingredient for cosmetic applications, particularly in treating androgenic-related skin conditions.

This study found that mouse embryonic fibroblasts better supported the growth and maintenance of LGR5+ epidermal stem cells compared to porcine fetal fibroblasts, under various culture conditions.

In this study, researchers investigated the penetration and cellular responses to nanoplastics in human skin models with compromised barriers, finding that nanoplastics can penetrate the skin, accumulate in cells, and trigger inflammatory responses through specific signaling pathways.

This study found that extracellular vesicles derived from hair follicle mesenchymal stromal cells demonstrated similar potential to those from adipose tissue in promoting cell proliferation and migration, enhancing angiogenesis, and protecting cells under stress, suggesting promise for chronic wound treatment.

This study found that Forskolin-loaded carboxymethyl chitosan-silk nanofiber hydrogels promoted wound healing by accelerating wound closure, enhancing neovascularization, and supporting hair follicle regeneration, while also being non-toxic and encouraging the proliferation of certain cell types.

The researchers presented a case study on Exo.Reset®, a cosmetic formulation using extracellular vesicle technology, demonstrating systematic application of recognized standards to ensure scientific rigor and regulatory compliance in skin rejuvenation product development, providing a practical model for EV-based cosmetic innovations.

In this study, researchers used a chemical cocktail and hydrogel microspheres to successfully guide fibroblasts into dermal papilla cells, promoting wound healing and in situ hair follicle regeneration while reducing scar formation, in both in vitro and in vivo experiments.

This study developed a biomimetic 3D skin model with vascularization potential to assess the impact of nano-zinc oxide (nano-ZnO), finding that nano-ZnO significantly influenced genes related to apoptosis, inflammation, and oxidative stress in skin cells.

This article reviews how the microenvironment influences adult stem cell behavior and discusses strategies to enhance stem cell function but reports no new experimental results.

This study found that injury affects the behavior of hair follicle dermal stem cells, steering them towards recruitment into the dermal papilla, a shift influenced by the hair cycle stage.

This study found that filamin A plays a crucial role in fibroblasts' ability to sense and respond to mechanical stimuli, significantly affecting wound closure and fibroblast-mediated processes in mice.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

This review highlights that surface mechanical regulation can program macrophage behavior through specific mechanical cues on material surfaces, potentially advancing immunotherapies and regenerative medicine by enabling precise control over macrophage functions.

The study found that silencing the gene p16INK4a in dermal papilla cells promotes their growth and aggregative behavior, suggesting a potential therapeutic target for androgenetic alopecia.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This study suggests that inhibitors of steroidogenic enzymes may have therapeutic potential for certain behavioral disorders linked to dopaminergic hyperfunction, despite concerns about their endocrine impacts.

This study found that abolishing H3K27me3 in mouse skin by targeting Ezh2 and Ezh1 affects hair follicle development and epidermal behavior, revealing functional differences between these tissues.

In this study, TC-1 cells, resembling stromal cells formed by epithelial-mesenchymal transition, significantly affected the behavior of normal human keratinocytes, supporting the role of stromal cells in tumor progression.

This review summarizes discussions from a 2010 stem cell biology meeting, covering the origin, behavior, and therapeutic potential of pluripotent and multipotent stem cells, without reporting new experimental findings.

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.

This study found that immune cells, including T cells and macrophages, significantly influence stem cell behavior and tissue regeneration by secreting cytokines and inflammatory factors in mice.

This case study in a renal transplant patient observed that eruptive KA-type SCCs exhibited aggressive behavior and genetic expression changes following intralesional chemotherapy, indicating potential caution against routine use of such treatments in similar cases.

This study reports a less invasive method for detecting human clock gene expression using hair follicle cells, which accurately reflects individual behavioral rhythms and suggests a time lag issue for rotating shift workers.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.
