Methods for the preparation of mast cell membrane sheets and immunogold labeling FcεRI have been described.
Most interestingly, the presence of EphA4 leads to a profound increase in the number of oligodendrocytes forming very large membrane sheets and (d)).
Building a nucleus at the end of mitosis involves the complete reconstruction of nuclear membrane sheets and macromolecular NPCs on two sets of de-condensing chromosomes.
Other studies have shown that Ca2+ ionophores cause retraction of membrane sheets and necrosis in cultured oligodendrocytes and induction of vesicular demyelination in vivo (Schlaepfer, 1977; Benjamins and Nedelkoska, 1996; Smith and Hall, 1994).
Fourth, a cell-free assay of endocytosis involving plasma membrane sheets and brain cytosol revealed that relative to WT, epsin-deficient cytosol results in an exaggerated and abnormal growth of the actin cytoskeleton.
Induction of spherical structures ("bulbs"), changes in the architecture of the ER from tubular to cisternal elements, expansion of smooth ER, formation of crystalloid ER, and emergence of vacuolar membrane sheets and foamy membrane structures inside the vacuole are proceeding in this order.
Membrane sheet tubulation and lipid monolayer surface pressure assays were performed as described previously (Cao et al, 2009).
Also spherical bodies are visible, but unlike the spherical structures in stages 1 and 2 they appear to be located in the cytoplasm, and large membrane sheets crossing and thereby compartmentalizing the central vacuole emerge.
In the presence of VOCC antagonists, there was strong inhibition of process extension and membrane sheet formation induced by golli, indicating that this remodelling was mediated by VOCCs (Paez et al., 2007).
