Pigment cell organization in the hypodermis of zebrafish

Developmental Dynamics, 2003
AbstractZebrafish have a characteristic horizontal‐stripe pigment pattern made by a specific distribution of three types of pigment cells: melanophores, xanthophores, and iridophores. This pattern is a valuable model to investigate how the spatial patterns form during animal development.

Differences in the protocollagen hydroxylase activities from Ascaris muscle and hypodermis

Archives of Biochemistry and Biophysics, 1970
Abstract Protocollagen hydroxylase (PCH) was partially purified from Ascaris lumbricoides muscle and from cuticle fluid. This fluid is found in the space formed between the cuticle and muscle layer when the worms are frozen at −40 ° for several days and then thawed.

The role of fibres and the hypodermis in Compositae melanin secretion

Micron, 2013
Melanins are dark, insoluble pigments that are resistant to concentrated acids and bleaching by oxidising agents. Phytomelanin (or phytomelan) is present in the seed coat of some Asparagales and in the fruits of some Compositae. In Compositae fruits, melanin is deposited in the schizogenous spaces between the hypodermis and underlying fibrous layer ...

Ecdysteroid Receptors: A Comparison of Cytoplasmic and Nuclear Receptors from Crayfish Hypodermis

Hoppe-Seyler´s Zeitschrift für physiologische Chemie, 1982
Cytoplasmic and nuclear ecdysteroid receptors from intermolt Orconectes limosus integument have been compared. The specificities as well as the KD values for three [3H]ecdysteroids are very similar in both preparations. Using a photoaffinity labelling technique, the molecular mass of the hormone-receptor complexes from both preparations was determined ...

Ascaris suum: Partial isolation and characterization of hypodermis from the adult female

Experimental Parasitology, 1987
A method was developed to remove the muscle from body wall strips of adult female Ascaris suum resulting in a hypodermis cuticle preparation. Optimum treatment for obtaining the hypodermis cuticle was a 15 min incubation with trypsin (2.0 mg/ml) at room temperature, followed by mechanical removal of the muscle.

STRUCTURE AND DEVELOPMENT OF HYPODERMIS IN DACRYDIUM TAXOIDES LEAVES

American Journal of Botany, 1953
MANY GYMNOSPERMS are characterized by the presence of one or more layers of thick-walled hypodermal cells arranged in various ways beneath the epidermal layer of the foliage leaf. These layers may vary in number with the species, with the age of the leaf, and with habitat.

The presence of pteridines in the hypodermis as a taxonomic tool in crayfish

Canadian Journal of Zoology, 1970
The hypodermis of nine species of crayfish, Cambarus bartoni, Cambarus diogenes, Cambarus fodiens, Cambarus robustus, Orconectes immunis, Orconectes obscurus, Orconectes propinquus, Orconectes rusticus, and Orconectes virilis, Found in central and southern Ontario was examined by thin layer chromatography cellulose sheets for pteridines.

Rectification of radial water flow in the hypodermis of nodal roots of Zea mays

Plant and Soil, 1988
The outer cells of the cortex in roots of some species may develop lamellar structure, usually assumed to contain suberin, to form a hypodermis immediately beneath the epidermal cells (Peterson, 1988). The hypodermis together with the epidermis and a few ranks of cortical collenchyma cells may be isolated from the central tissues of the root by enzymic

Characterization of cytoplasmic ecdysteroid receptors in the hypodermis of the crayfish, Orconectes limosus

Molecular and Cellular Endocrinology, 1981
[3H]Ecdysone, [3H]20-OH-ecdysone and [3H]ponasterone A were specifically bound by the 120 000 g supernatant of the homogenate from crayfish hypodermis. According to the HPLC test, the bound hormone was not metabolized. Analysis of the cytosol receptor by sucrose-density-gradient centrifugation, gel filtration and enzymatic degradation revealed the ...
