This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study observed that the thinning and structural abnormalities in monilethrix-affected hair occur at the internodes due to possible periodic dysfunction of the hair matrix, particularly in the cortex.

In this study, electron microscopy of follicular mucinosis showed severe cytoplasmic degeneration in hair follicles, with myelin figures and onion-like lamellar structures, but no indications of mucin release through degeneration or degradation were found.

In this study, researchers showed that multiphoton microscopy with fluorescent protein tagging enables single-cell imaging and tracking in live transgenic mice, offering new insights into cell dynamics in stem cell research compared to traditional histological methods.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This study utilized magnetic resonance imaging to noninvasively visualize and differentiate skin structures in rat skin, finding a significant correlation between MRI data and histological areas.

Miniaturized hair follicles in androgenetic alopecia show abnormal mitochondrial activity and damage.

This study shows that multiphoton microscopy can non-invasively distinguish scarring from non-scarring alopecia by identifying specific morphological features in hair follicle structures.

This review discusses recent advances in droplet microfluidics for chip-based technologies such as single-cell analysis, small-scale cell cultures, and high-throughput drug screening, and it reports no new results.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

This glossary abstract does not present new research findings but provides definitions of medical and anatomical terms relevant to various procedures and conditions.

This study observed that the lower part of vibrissa hair roots in adult Wistar rats receives a richer blood supply and structural protection, compared to the upper part.

This study found that basement membrane components and structures in mouse hair follicles are highly specialized for specific inter-tissue interactions, with laminin α5 playing a crucial role in hair cycle regulation and anchoring.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This article discusses the structures surrounding hair follicles and introduces aspects like follicle groups and the dermal sheath, but it reports no new research findings.

This study observed that the mechanical connection between hair follicles and connective tissue in human fetal scalp skin is weaker than in the corresponding skin components, reflecting dynamic processes in hair growth.

This study generated a transcriptomic map of human hair follicles, identifying compartment-specific gene expression profiles that can aid in developing targeted therapies for hair follicle disorders.

This study developed a comprehensive atlas of human scalp tissue to uncover cell states and lineages in hair follicles, identifying disease-specific cellular changes associated with non-scarring and scarring hair loss, which may offer new diagnostic and therapeutic insights.

This study observed that in mouse fetuses, reticular contraction by actomyosin is involved in dermal regeneration, and differences in actin and α-SMA localization may determine the switch between regeneration and scar formation, suggesting potential insights for wound regeneration therapy.

This study developed a 3D ovarian cancer model using microtumours, which effectively mimics minimal residual disease and supports the identification of new drug targets like perhexiline for treatment-resistant cells.

This study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.

This article discusses the structure of hair follicles and their significance in evaluating hair disorders, but it does not report any new research findings.

This study found that examining the microscopic and ultramicroscopic structures of donkey and horse hair can help differentiate between the species based on distinct differences in hair cuticle and brain substance patterns.

This article discusses a new device for visualizing and quantifying skin distribution of a radioactively labelled compound, but reports no new clinical results.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

This study used phase contrast hard x-ray microscopy to capture detailed images of healthy human hair, revealing distinct structures such as the medulla, cortex, and cuticular layer.

This study observed that in live rodents, actin filaments adjust their structure to facilitate membrane transfer between cellular compartments; linear filaments stabilize fused membranes, while branched filaments, connected by the protein Ezrin, drive integration, demonstrating actin's role in adapting to membrane biophysical changes.

This review discusses novel molecular techniques in skin appendage research and summarizes the distribution of key molecules, but it reports no new experimental results.
