In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

This study presents the first detailed 3D models of the complete K1/K10 keratin dimer and identifies structural features and interactions that may inform understanding of keratin filament assembly.

This study found that human dermal papilla cells are embedded in a basement membrane-like extracellular matrix, which is essential for their aggregation and function, as supported by evidence that Matrigel enhances dermal papilla cohesion and gene expression compared to collagen I, which promotes cell dispersion.

This study identified two key pentapeptide quasi-repeats in human keratin-associated proteins, which are similar to motifs found in sheep wool.

In this study, curcumin-loaded nanoparticles with a size of 400 nm showed optimal accumulation in human hair follicles after seven days, although mouse models differed significantly in penetration and retention, indicating limitations in their suitability for follicular drug delivery studies.

In this study, the researchers found that trichoscopy can effectively visualize scalp micropigmentation, identified by homogenous, grey to black circular dots similar to closely cut hair, potentially reducing the need for invasive procedures.

This study found that asynchronous differentiation in human anagen hair follicles involves specific localization of c-Myc and interrelated genes Max and Bin1 along the inner root sheath.

This study found that in Japanese, German, and American females, changes in hair lipid patterns with age may reflect alterations in sebum excretion and affect hair texture.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

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 nanoparticles can penetrate the skin, but artifacts produced during specimen preparation complicate accurate observation, and proposed a method for reducing errors in imaging quantum dots as tracers.

This study suggests that subtle modifications in ribosomal RNA methylation may influence cellular physiology and contribute to ribosome specialization in senescent human dermal fibroblasts.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study found that microencapsulated dermal papilla cells implanted into mice ears led to the successful regeneration of hair follicles, with APA microencapsulations of 400µm diameter allowing effective nutrient exchange.

This study found that cultured human dermal papilla cells formed into three-dimensional spheres have an increased ability to induce hair follicles from mouse epidermal cells compared to two-dimensional cultures.

This study outlines a method for isolating dermal papilla cells from human hair follicles, which may help overcome challenges in studying their role in hair growth.

Scalp micropigmentation is a process where tiny dots of pigment are tattooed onto the scalp to create the appearance of a shaved head or fuller hair.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

This article reviews the rationale and science behind forensic hair examinations and discusses the role of microscopic and DNA techniques in differentiating hair sources but reports no new findings.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This review discusses the role of Ysc84/SH3yl1 proteins in linking actin regulation to membrane morphology changes but reports no new experimental results.

This study cataloged several long non-coding RNAs and microRNAs in cashmere goat dermal papilla cells, suggesting these non-coding RNAs may play a role in hair follicle stem cell activation and hair growth.

This study found that an extracellular calcium binding site gradient exists in mouse vibrissa and human scalp follicles, but is not significantly affected by hair growth-altering drugs or epidermal growth factor.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

In this study, a method using nano-sized iron particles successfully captured images of sub-dermal hair follicles, showing comparable size and shape to those removed from the skin.

This study used fibre optic confocal imaging to visualize subsurface structures in live mouse skin, revealing cellular details and blood vessel networks that dynamic events could be studied in vivo.
