Germ line Cysts and the Formation of the Germinal Epithelium During the Female Gonadal Morphogenesis in Cyprinus Carpio (Teleostei: Ostariophysi: Cypriniformes)
(Wiley-liss, 2010-09-01)
The formation of both germline cysts and the germinal epithelium is described during the ovary development in Cyprinus carpio. As in the undifferentiated gonad of mammals, cords of PGCs become oogonia when they are surrounded ...
Ras regulation of actin polarization in cryptococcus neoformans [Ras regulación de la polarización de actina dn cryptococcus neoformans]
(2020)
The mechanisms by which cells sense and adapt to changes in the environment are mediated by conserved signal transduction pathways that couple specific extracellular signals to defined cellular outputs. Ras proteins are ...
A grande colisão pré-cambriana do sudeste brasileiro e a estruturação regional
(2010-09-27)
This paper presents a review on the geotectonic framework of the Southeastern Brazil and neighborhoods, and its importance in the regional geologic evolution, which was exposed as a main conference at the XI Symposium of ...
Postnatal development of Mongolian gerbil female prostate: An immunohistochemical and 3D modeling study
(2016-05-01)
The development of the prostate in male rodents, which involves complex epithelial-mesenchymal interactions between the urogenital sinus epithelium (UGE) and the urogenital sinus mesenchyme (UGM), has been deeply studied. ...
Intensive production and management of marandu palisadegrass (Urochloa brizantha ‘marandu’) accelerates leaf turnover but does not change herbage mass
(2021-09-01)
Pasture intensification through higher stocking rates, nitrogen fertilization and intensified grazing management in beef cattle production optimizes pasture use by increasing the forage har-vested. We aimed to assess its ...
Simulations of virtual plants reveal a role for SERRATE in the response of leaf development to light in Arabidopsis thaliana
(2007)
• The SERRATE gene (SE) was shown to determine leaf organogenesis and morphogenesis patterning in Arabidopsis thaliana. The se-1 mutant was used here to investigate the role of SE in leaf development in response to incident ...
The developmental nephrome: systems biology in the developing kidney
(Lippincott Williams & Wilkins, 2007-01-01)
Purpose of reviewA set of important genes and signaling pathways involved in kidney development is emerging from analyses of mutant mice, in-vitro models, and global gene expression patterns. Conversion of data into dynamic ...
Function of rotavirus VP3 polypeptide in viral morphogenesis
(1993)
The phenotype of the rotavirus SA-11 mutant tsB carrying a thermosensitive mutation in gene 3, which encodes VP3, was characterized further from both infected cells and purified viral particles. The mutant phenotype was ...
Heparin Activates Wnt Signaling for Neuronal Morphogenesis
(2008)
Wnt factors are secreted ligands that affect different aspects of the nervous system behavior like neurodevelopment, synaptogenesis and neurodegeneration. In different model systems, Wnt signaling has been demonstrated to ...
Differences in mushroom bodies morphogenesis in workers, queens and drones of Apis mellifera: Neuroblasts proliferation and death
(Pergamon-Elsevier B.V. Ltd, 2010-06-01)
Apis mellifera is an interesting model to neurobiological studies. It has a relatively small brain that commands the complex learning and memory tasks demanded by the social organization. An A. mellifera colony is made up ...
