870-900 / 1000+ resultsresearch The structure of the cornified claw sheath in the domesticated cat (Felis catus): implications for the claw‐shedding mechanism and the evolution of cornified digital end organs
Cat claws stay sharp by shedding their outer layer through microcracks formed during activities.
research Optimal skin regeneration after full thickness thermal burn injury in the spiny mouse, Acomys cahirinus
The spiny mouse can fully regenerate skin after burns, unlike the lab mouse.
research Outer root sheath keratinization in anagen and catagen of the mammalian hair follicle. A seventh distinct type of keratinization in the hair follicle: trichilemmal keratinization.
Trichilemmal keratinization is a unique process in hair follicles where the outer root sheath turns into keratin without a specific layer.
research Cutaneous epitheliotropic T‐cell lymphoma in a sugar glider (Petaurus breviceps)
A sugar glider had a rare skin cancer that worsened despite treatment, highlighting the need for thorough checks in exotic pets.
research Catagen in the hairless house mouse
Hairless mice have longer hair follicles and abnormal structures during the catagen phase.
research Mode of redifferentiation and melanogenesis of melanocytes in mouse hair follicles
research Spiny mice ( Acomys ) have evolved cellular features to support regenerative healing
Spiny mice can regenerate tissues instead of forming scars.
research The Microanatomy, Cell Replication, and Keratin Gene Expression of Hair Follicles during a Photoperiod-lnduced Growth Cycle in Sheep
Changing light periods synchronized wool growth cycles in sheep.
research Vesicle Formation and Follicular Root Sheath Separation in Mice Homozygous for Deleterious Alleles at the Balding (bal) Locus
A mutation in mice causes hair loss and skin issues due to a defect in a gene affecting cell adhesion.
research Preovulatory oocyte transfer to a preovulatory follicle: An alternative to in vitro fertilization in the mare
research Moth eaten alopecia as a manifestation of group of skin diseases: Reporting a series of 100 cases
Moth-eaten alopecia is linked to various skin diseases and requires early treatment to prevent worsening.
research Hair Shedding Bethesda
research Piebaldism in tree shrews
research A null mutation in the cystatin M/E gene of ichq mice causes juvenile lethality and defects in epidermal cornification
A gene mutation in mice causes skin defects and early death.
research Metallothionein expression during wool follicle development in foetal sheep
Metallothionein likely helps in cell growth and development in wool follicles of fetal sheep.
research Distinct mechanisms underlie pattern formation in the skin and skin appendages
Different processes create patterns in skin and things like hair and feathers.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research Defolliculated (Dfl): A Dominant Mouse Mutation Leading to Poor Sebaceous Gland Differentiation and Total Elimination of Pelage Follicles
The Dfl mutation in mice causes poor sebaceous gland function and complete hair loss.
research Melanogenesis During the Anagen-Catagen-Telogen Transformation of the Murine Hair Cycle
Hair stops producing melanin as it transitions from the growth phase to the resting phase.
research Seasonal Variability in Transcript Expression of Type I and Type II Keratins in Wool Follicles of Lustrous Fleece-Producing Magra Sheep
Higher keratin protein levels are important for the wool's shine in Magra sheep.
research Cyclic hair-loss and regrowth in transgenic mice overexpressing an intermediate filament gene.
Mice with extra sheep genes had hair that fell out and regrew in cycles.
research Telogen Effluvium
Telogen Effluvium causes more hair loss because hair moves to the resting phase too soon.
research Miscellaneous Skin Diseases
Sheep can lose wool quickly due to stress, but it doesn't cause itching or pain.
research Expansion of specialized epidermis induced by hormonal state and mechanical strain
Hormones and stretching both needed for nipple area skin growth in mice.
research Expansion of specialized epidermis induced by hormonal state and mechanical strain
Nipple area expansion in mice needs both pregnancy hormones and mechanical strain.
research The Naked (N) Mutation, Chromosome 15
The naked mutation in mice causes hair loss and helps identify keratin genes.
research Mode of action of mouse epidermal growth factor on the wool follicles of Merino sheep: an ultrastructural study
Mouse epidermal growth factor temporarily stops wool growth and causes cell changes in Merino sheep.
research A new species ofAplodontopus(Acari: Astigmata: Chortoglyphidae) from the yellow-bellied marmot,Marmota flaviventris(Rodentia: Sciuridae) in Eastern Washington, USA, with observations on its pathology
Researchers found a new mite species causing severe hair loss and skin problems in yellow-bellied marmots.
research The Shaven (Sha) Mutation, Chromosome 15
The Shaven mutation in mice affects hair growth and causes a greasy coat due to abnormal lipid content.
