Studies of multinucleate cells indicate that the amount of cytoplasm surrounding a nucleus determines its size1,7,8. In vitro experiments with Xenopus egg extracts9,10 and a genetic screen in fission yeast11 have implicated nuclear lamina components, nucleocytoplasmic transport, and overall lipid ...
The membranes surrounding each cell (plasma membrane) and the intracellular structures (endoplasmatic reticulum, Golgi apparatus, nuclear membrane, mitochondria membranes, other organelle membrane) are not only composed of lipids but incorporate proteins and steroids as well. Besides this,adsorbed proteins...
The cell membrane also allows the entry of nutrients and exit of harmful substances.Cell Membrane The membrane surrounding the cell, separating it from its external environment is the cell membrane. In plant cells, it is located between the cell wall and the cytoplasm. It is also known as ...
chorioallantoic membrane,chorioallantois- the very vascular fetal membrane composed of the fused chorion and adjacent wall of the allantois web- membrane connecting the toes of some aquatic birds and mammals Bowman's capsule,capsula glomeruli,glomerular capsule- thin double membrane surrounding the glomeru...
The cellular location of these divergent Drps changed dramatically during encystation from a punctate diffuse localization to one surrounding the nucleus in the mature cyst suggesting an association with the ER. Further co-localization and knock-down experiments will allow us to understand the role of...
Fig. 3. Diagram of oscillatory membrane system used in the experiments. The membrane oscillation created a shear rate in the surrounding liquid. The generated shear rate was found to be a function of velocity at the membrane surface [14], angular frequency ω (ω = 2πF) and velocity ampli...

The nucleus has chiefly to do with the multiplication of the cell and contains the factors which determine heredity. The mass outside of the nucleus is termed "cytoplasm," and this may be homogeneous in appearance or may contain granules. On the outside there is a more or less definite ...
During apoptosis, concomitantly with permeabilization of the mitochondrial outer membrane (MOMP) and cytochrome c release, mitochondria undergo massive fission. This results in the formation of small, round organelles that tend to aggregate around the nucleus. Under some circumstances, preceding their ...
