The extracellular matrix provides directional cues for neuronal migration during cerebellar development
Provedor de dados: 56
Autores: Porcionatto,M.A.
Normal central nervous system development relies on accurate intrinsic cellular programs as well as on extrinsic informative cues provided by extracellular molecules. Migration of neuronal progenitors from defined proliferative zones to their final location is a key event during embryonic and postnatal development. Extracellular matrix components play important roles in these processes, and interactions between neurons and extracellular matrix are fundamental for the normal development of the central nervous system. Guidance cues are provided by extracellular factors that orient neuronal migration. During cerebellar development, the extracellular matrix molecules laminin and fibronectin give support to neuronal precursor migration, while other molecules...

Heparan sulfate and cell division
Provedor de dados: 56
Autores: Porcionatto,M.A.; Nader,H.B.; Dietrich,C.P.
Heparan sulfate is a component of vertebrate and invertebrate tissues which appears during the cytodifferentiation stage of embryonic development. Its structure varies according to the tissue and species of origin and is modified during neoplastic transformation. Several lines of experimental evidence suggest that heparan sulfate plays a role in cellular recognition, cellular adhesion and growth control. Heparan sulfate can participate in the process of cell division in two distinct ways, either as a positive or negative modulator of cellular proliferation, or as a response to a mitogenic stimulus.

Heparan sulfates and heparins: similar compounds performing the same functions in vertebrates and invertebrates?
Provedor de dados: 56
Autores: Nader,H.B.; Chavante,S.F.; dos-Santos,E.A.; Oliveira,F.W.; de-Paiva,J.F.; Jerônimo,S.M.B.; Medeiros,G.F.; de-Abreu,L.R.D.; Leite,E.L.; de-Sousa-Filho,J.F.; Castro,R.A.B.; Toma,L.; Tersariol,I.L.S.; Porcionatto,M.A.; Dietrich,C.P.
The distribution and structure of heparan sulfate and heparin are briefly reviewed. Heparan sulfate is a ubiquitous compound of animal cells whose structure has been maintained throughout evolution, showing an enormous variability regarding the relative amounts of its disaccharide units. Heparin, on the other hand, is present only in a few tissues and species of the animal kingdom and in the form of granules inside organelles in the cytoplasm of special cells. Thus, the distribution as well as the main structural features of the molecule, including its main disaccharide unit, have been maintained through evolution. These and other studies led to the proposal that heparan sulfate may be involved in the cell-cell recognition phenomena and control of cell...
