research Production of ultraviolet-light-induced skin erythema in the hairless rat: a comparison with the haired rat in screening for anti-inflammatory drugs
Hairless rats are good for testing anti-inflammatory drugs, similar to haired rats, without needing to remove fur.
research Cutaneous Hybrid Cyst in a Sprague-Dawley Rat
A rat had a cyst similar to a hair follicle structure.
research Directing Rat Hair Follicle Stem Cells Toward Neuronal Lineage With Enhanced Trophic Factor Expression
Chick embryo extract helps rat hair follicle stem cells become more like neurons.
research Divergent neuroactive steroid responses to stress and ethanol in rat and mouse strains: relevance for human studies
Different rat and mouse strains respond differently to stress and alcohol, which may help us understand similar human mechanisms.
research [Experimental study on vascular endothelial growth factor 165 gene-modified rat hair follicle stem cells mediated by lentiviral vector].
Modified rat hair follicle stem cells can help create artificial hair follicles, blood vessels, and skin.
research Inhibition of rat α-reductases by finasteride: Evidence for isozyme differences in the mechanism of inhibition
Finasteride effectively blocks rat enzymes, but with varying methods and strength.
research Critical Developmental Periods for Effects on Male Rat Genitalia Induced by Finasteride, a 5α-Reductase Inhibitor
Finasteride affects male rat genitalia development, causing abnormalities during specific pregnancy days.
research Mechanism of progesterone neuroprotection of rat cerebellar Purkinje cells following oxygen–glucose deprivation
Progesterone protects rat brain cells by enhancing GABA A receptor activity.
research Localization of Zinc in a Dense Fiber-Connecting Piece Fraction of Rat Sperm Tails Analogous Chemically to Hair Keratin
Most zinc in rat sperm is in the tail, linked to structures similar to hair keratin.
research Epithelial Growth by Rat Vibrissae Follicles In Vitro Requires Mesenchymal Contact via Native Extracellular Matrix
Epithelial cell growth in rat hair follicles needs contact with mesenchymal cells through the extracellular matrix.
research The lanceolate hair rat phenotype results from a missense mutation in a calcium coordinating site of the desmoglein 4 gene
A gene mutation causes lanceolate hair in rats by disrupting hair shaft integrity.
research Cultured human and rat tooth papilla cells induce hair follicle regeneration and fiber growth
Tooth papilla cells can help regenerate hair follicles and grow hair.
research Identification of the Rat Rex Mutation as a 7-bp Deletion at Splicing Acceptor Site of the Krt71 Gene

research Inhibition of Rat 5α-Reductase Activity and Testosterone-Induced Sebum Synthesis in Hamster Sebocytes by an Extract ofQuercus acutissimaCortex
An extract from Quercus acutissima bark was found to reduce sebum production and block an enzyme linked to acne.
research The effects of epilation and hormones on the activity of rat hair follicles
Epilation doesn't affect rat hair growth; thyroxine speeds it up, while estradiol slows it down.
research Effects of PNU157706, a Dual 5α-Reductase Inhibitor, on Rat Epididymal Sperm Maturation and Fertility1
PNU157706 reduced rat sperm movement and fertility without affecting offspring health.

Myofibroblasts in rat wound healing may come from blood vessel pericytes and perifollicular dermal sheath cells.
research Androgen receptor in rat liver: Characterization and separation from a male-specific estrogen-binding protein
Male rats have androgen receptors in their liver, which are different from proteins that bind estrogen.
research Interaction of spironolactone with rat skin androgen receptor
Spironolactone reduces the number of androgen receptor sites in rat skin by blocking them with its metabolite.
