Dynamic somite cell rearrangements lead to distinct waves of myotome growth
(Company of Biologists, 2007-04)
The myogenic precursors responsible for muscle growth in amniotes develop from thedermomyotome, an epithelium at the external surface of the somite. In teleosts, themyogenic precursors responsible for growth have not been ...
Histology of the hepatopancreas and anterior intestine in the freshwater prawn Macrobrachium carcinus (Crustacea, Decapoda)
(Soc Brasileira Carcinologia, 2020-07-13)
The purpose of this study was to describe the structure of the midgut (hepatopancreas and intestine) in the endemic species, Macrobrachium carcinus. Thirty specimens were collected, and the midgut was fixed in Bouin's ...
Posteriorization by FGF, Wnt, and retinoic acid is required for neural crest induction
(Academic Press Inc., 2002)
The neural crest is a unique cell population induced at the lateral border of the neural plate. Neural crest is not produced at the anterior border of the neural plate, which is fated to become forebrain. Here, the roles ...
Functional architecture of the rat parasubiculum
(Society for Neuroscience, 2016)
The parasubiculum is a major input structure of layer 2 of medial entorhinal cortex, where most grid cells are found. Here we investigated parasubicular circuits of the rat by anatomical analysis combined with juxtacellular ...
Extracellular signals, cell interactions and transcription factors involved in the induction of the neural crest cells
(Sociedad de Biología de Chile, 2002)
Extracellular signals, cell interactions and transcription factors involved in the induction of the neural crest cells
(Society of Biology of Chile, 2002)
The neural crest is induced at the border between the neural plate and the epidermis. A complex set of signals is required for the specification of the crest cells between the epidermis and the neural plate. Here we discuss ...
Morphology and histochemistry of the digestive tract in carnivorous freshwater Hemisorubim platyrhynchos (Siluriformes: Pimelodidae)
(Elsevier B.V., 2014-09-01)
The aim of this study was to characterize the morphology and histochemistry of the digestive tract of Hemisorubim platyrhynchos, a freshwater carnivorous catfish found in Neotropical region, using gross anatomy, light ...
Neural crests are actively precluded from the anterior neural fold by a novel inhibitory mechanism dependent on Dickkopf1 secreted by the prechordal mesoderm
(Academic Press Inc., 2007)
It is known the interactions between the neural plate and epidermis generate neural crest (NC), but it is unknown why the NC develops only at the lateral border of the neural plate and not in the anterior fold. Using ...
Epitheliotropic cutaneous T-cell lymphoma associated with melanoma in a dog: case report
(Universidade Federal de Minas Gerais, Escola de Veterinária, 2015-06-01)
Several types of tumors affect dogs' skin. Simultaneously occurring neoplasms with different histological patterns might be rarely present in the same animal. This paper describes the occurrence of epitheliotropic cutaneous ...
Diferenciação de duas espécies crípticas de planárias terrestres do gênero Geoplana (Platyhelminthes: Tricladida: Continenticola) ocorrentes em diferentes formações florestais do sul do Brasil
(Universidade do Vale do Rio dos Sinos, 2013-02-28)
According to its original description, the type-specimens of Geoplana ladislavii Graff, 1899 are characterized by having a green-colored dorsum. When redescribed, specimens with greenish-brown color were also considered ...
