PDF-Development of Zebrafish Epidermis WeiJen Chang and Pu

In this review we summarize current findings about the development of the zebrafish epidermis and demonstrate how the zebrafish regulate stress acclima tion through induction of cell differentiation In addition cellular homol ogies between zebrafish. 2. . Melanocytes. : Found deep in the epidermis, as melanin is made it accumulates in . granules called . melanosomes. . . Exposure to sunlight can also increase the amount of melanin produced.. Skin color . What are the major characteristics of the skin?. Waterproof, stretchable,washable, and permanent-press, that automatically repairs small cuts, rips and burns and is guaranteed to last a lifetime.. Surface area of up to 2.2 square meters. . zebrafish. model for inflammatory bowel disease (IBD): preliminary results. Simon Haarder. 1, 3. , Per Kania. 1. , Poul Hyttel. 2. , Thomas . Lindebo. Holm. 3. and Kurt Buchmann. 1. 1 . THE INTEGUMENTARY IS THE LARGEST ORGAN OF THE BODY. IT CONSISTS OF TWO COMPONENTS:(1) THE SKIN, AND (2)THE EPIDERMAL DERIVATIVES, SUCH AS THE HAIR, NAILS AND GLANDS.. THE SKIN IS OF PARTICULAR SIGNIFICANCE IN A CLINICAL EXAMINATION. FOR EXAMPLE, THE COLOR OFTHE SKIN MAY INDICATE THE EXISTENCE OF A PATHOLOGIC CONDITION: A YELLOW COLOR INDICATES JAUNDICE; A BLUE-GRAY COLOR MAY INDICATE CYANOSIS, REFLECTING A PATHOLOGIC CONDITION OF CARDIOVASCULAR AND RESPIRATORY FUNCTION S; A PALE COLOR IS INDICATIVE OF ANEMIA; LACK OF SKIN PIGMENTATION SUGGESTS ALBINISM, A GENETIC TRAIT CHARACTARIZED BY LACK OF THE ENZYME TYROSINASE, INVOLVED IN THE CONVERSION OF THE AMINO ACID TYROSINE TO MELANIN.. Patients . having an . aberrant ENS . (i.e. . Hirschsrpung . disease) . have increased susceptibility to gut inflammation and altered microbiota. . . It is unknown why some patients with aberrant ENS have inflammation. Hello scientists. ,. Welcome to . BioEYES. ! We are bringing you an exciting experiment. For the next week your goal will be to learn all you can about . zebrafish. and their similarities to humans. You will work with the . Two kinds of tissue compose the skin. Epidermis. Dermis. Hypodermis (subcutaneous layer) . Anchors the skin to underlying organs. Not technically part of the integumentary system. Composed mostly of adipose tissue. Mary Mitchell, JC Achenbach, Sean .

The . integumentary. system consists of the . skin. , . hair. , . nails. , and . glands. .. . Functions. : . protection of internal structures (from abrasion & UV light). zebrafish. ???. Can house a lot of genetically distinct lines in not a lot of space!. Isolated mutations in hundreds of genes which affect embryonic development. Inherited mutations in some genes predisposes fish – like humans! – to cancer.
