This study observed that storing hair follicle micrografts significantly decreased the expression of certain key genes in the dermal papilla, potentially affecting hair follicle cycling during preparation and storage.

In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.

This study found that aging in Korean individuals is associated with changes in hair diameter and surface structure, as observed through atomic force microscopy.

This study found that cultured outer root sheath cells from human hair follicles expressed a keratin profile similar to their in vivo environment, indicating environmental influence on keratin expression.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

This study found that disruptions in planar cell polarity signaling are implicated in congenital heart defects and cardiomyopathy in developing mouse hearts, associated with early cardiomyocyte disorganization and improper heart looping.

A woman with Parry-Romberg syndrome developed new curly hair on one side of her scalp, a condition not previously linked to the syndrome.

This review discusses recent advancements in understanding hair follicles, their disorders, and potential therapeutic opportunities, but it reports no new clinical findings.

This study observed that during male silkmoth development, trichogen cells in olfactory sensilla undergo significant membrane recycling, contributing to sensillum structure formation in a precisely timed series of stages.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This report describes two children with congenital hypotrichosis and found their short hair is due to a shortened anagen phase, with the condition resolving spontaneously during puberty.

This case study describes a 14-year-old girl with pili annulati who had fragile hair, which may be due to cavities within the hair shafts as seen in electron microscopic examinations.

The document explains how hair follicles develop, their structure, and how they grow.

This study found that hair with lower levels of keratin associated proteins reduced the foreign body response in mouse subcutaneous implant tests compared to hair with higher keratin levels.

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

This study found that transient activation of c-Myc in transgenic mice stimulates keratinocyte proliferation and sebocyte differentiation, affecting normal epidermal and hair follicle development.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This study found that the enzyme A20 helps regulate EDAR-induced NF-κB signaling in mice, preventing ectodermal abnormalities like disheveled hair and assuring proper skin and appendage development.

This study observed that after hair cell loss in the mouse cochlea, supporting cells were replaced by migrating non-specialised cells, with genetic background affecting the rate of tissue re-organization.

This study identified a new genetic locus, ahl4, on distal Chromosome 10 that contributes to the early-onset, severe hearing loss in A/J mice compared to B6 mice.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

This study found that GDNF promotes hair formation and skin wound repair by enhancing the self-renewal and differentiation of bulge stem cells in mice.

This study found that African and Caucasian hair contain the most lipids, and depletion of these lipids leads to less water retention and increased water desorption, with Caucasian hair showing improved breaking tenacity after lipid extraction.
