Abstract
Each time a metazoan cell undergoes open mitosis, the nucleus is dismantled in order to partition DNA content to the daughter cells. After chromosomes separate, changes at the chromatin surface usher in reestablishment of nuclear architecture. Proteins destined for the nuclear envelope are attracted to chromatin and concomitantly recruit membrane. As nuclear envelope and protein constituents spread to coat chromatin, distinct regions emerge-some rich in rapid pore formation, others occupied by microtubules that remain attached to kinetochores. Microtubule connections present physical barriers that must be remodeled in order for the nuclear envelope to seal. Regions of the nascent nuclear envelope that are initially characterized by contrasting repertoires of nuclear envelope proteins rapidly coalesce as nuclei expand and enter interphase.

Abstract
An increased activity of membranes of the nuclear envelope (NE) was observed electron microscopically in the trophoblast cells of the rat placenta. The activity of the membranes was manifested as formation of various NE derivatives, such as the annulate lamellae (AL), the intranuclear tubules, and the concentric membranous structures. At the period of terminal differentiation of the secondary giant trophoblast cells (SGTC) the NE derivatives play active role in subdivision of the initial highly polyploid nuclei into the numerous low-ploidy fragments. (3)H-thymidine labeling showed that attenuation of the DNA replication precedes the nuclear fragmentation. In the course of the nuclear fragmentation the narrow deep NE invaginations subdivide the nucleus into the separate lobes that subsequently are detached from the initial nucleus. By the beginning of the fragmentation, the accumulated membranous structures, i.e. the intranuclear AL, tubules, clusters of pore complexes, etc., seem to be the source of the reserve material that is necessary for formation of the great amount of the NE membranes of the newly formed nuclear fragments. Thus, the intranuclear membranous structures that seem to increase the active surface of the growing endopolyploid nucleus at the earlier stage of differentiation then take part in genome isolation that results in formation of a multinucleate cell with diploid and low-polyploid nuclei. The outer NE membrane of the initial nucleus plays an active role in compartmentalization of cytoplasmic areas around the nuclear fragments within the giant polykaryocyte. Apart from the membranous structures the bundles of intermediate filaments (IF) located in the cytoplasm perinuclear zones seem to participate in the nuclear fragmentation. These processes are likely to provide formation of the giant polykaryocytes incapable for further proliferation.

Abstract
The aim of this study was to examine the relationship between viral infection and annulate lamellae (AL) production by using quantitative and qualitative electron microscopy to document the size and numbers of AL in BS-C-1 cells infected with a lytic strain of hepatitis A virus (HAV). The progress of the HAV infection was found to occur in two phases. In phase 1, cell proliferation and cell death were roughly the same as that of the mock infected control, but there was an increase with time in the amount of hepatitis A antigen in the infected cells. In phase 2 cell division was minimal and cell death became manifest. AL were detected in both infected and control cells. Quantitative analysis indicated that the average number of AL was greater in infected cells compared to that in control cells in phase 1; in infected cells there were greater numbers of AL in phase 1 than in phase 2; the average number of membraneous leaves/AL was greater in infected cells than in control cells. Quantitative analysis also indicated that AL were very rare, with only about three AL per entire control cell and eight AL per entire infected cell. The study clearly establishes that viral infection can stimulate AL production. The data suggest stimulation of AL production in the virus infected cells was linked to the synthesis of viral antigen. Ultrastructural observations indicated that AL could be derived from either the rough endoplasmic reticulum or the nuclear membrane.

Abstract
To investigate annulate lamellae (AL) with nuclear changes, ultrastructural time course studies were done of the reversible end-plate myopathy in the soleus muscles of rats exposed chronically to a high dose of the anticholinesterase drug neostigmine. At the earliest stage (2 hours) in which severe subjunctional damage involving a nuclear lesion (nuclear pyknosis) was prominent, AL profiles were undetectable. At the intermediate stage (7, 21 days), in which the subjunctional organelles tended to cluster and nuclear pyknosis often accompanied degenerative features, most AL laid near the surface of the abnormal nuclei, where there were signs of elimination or formation of pores, as well as a progression of changes leading to the loss of pores. At the late stage (56 days), in which muscle repair was nearly completed and euchromatic nuclei usually were found, there was a concomitant enhanced formation of false nuclear inclusions and of the AL profiles in these sites. Pores are packed on nuclear envelopes, which detach themselves from the nucleus and take the same profile as AL. This phenomenon can be envisioned not only in the euchromatic but also in the abnormal (pyknotic or degenerated) nuclei. Following nuclear reconstitution, the nuclear envelope folding is accelerated to induce the usual pattern of AL organization, i.e., budding from the invaginated nuclear envelope.

Abstract
This review aims to provide a comprehensive and in-depth survey of a cell organelle, the annulate lamellae, that is widely distributed and especially prevalent in both female and male sex cells as well as tumor and cancer cells. The organelle is also present in many somatic cells and plant cells. Emphasis is placed on the contributions that electron microscopy and associated experimental approaches have made in providing information about the distribution, ultrastructure, morphogenesis and relationships of annulate lamellae to other cellular organelles, especially the nuclear envelope and endoplasmic reticulum, as well as cell product. An increasing number of experimental manipulations have recently been shown to alter, either increase or decrease, the amount of annulate lamellae and these studies are explored in depth. Information about the origin and morphogenesis of annulate lamellae in different cells is summarized and extensive coverage is given to several hypotheses about possible annulate lamellae function. A detailed bibliography provides a thorough compilation of research dealing with annulate lamellae. A major goal of this extensive review is to generate increased awareness of, and interest in, this cell organelle for students and investigators of the cell who, by bringing current techniques in cell and molecular biology to bear, might focus and intensify studies on the function of an organelle whose precise role in the cell is presently enigmatic.

Abstract
Annulate lamellae (AL) are a membranous structure frequently observed in differentiating gametes and tumor cells. In spite of numerous morphological studies, the function and biochemical composition of this membrane system are not well understood. In this study, we have examined the AL membrane system of vinblastine-treated mouse L cells using immunocytochemistry and Western blot analysis. Our results show that antibodies directed against nuclear envelope lamins, i.e., lamins A, B, and C, did not cross react with constituents of the AL membrane system. Furthermore an AL-specific antibody failed to react with the nuclear envelope and reacted minimally producing only a background stain over other cellular components. The data suggest that the AL membrane system has a distinct molecular make-up that is antigenically distinct from that of other subcellular structures.

Abstract
The anterior limb bud mesenchyme cells of stage 24 chick embryos were dissociated by trypsinization followed by gentle pipetting, and placed in a tissue culture medium of F12 containing 10% fetal calf serum and antibiotics. As the cells became nearly confluent, some of them were exposed to colchicine or vinblastine sulfate for durations as long as 48 hr. The control and antitubulin-treated cells were processed for transmission electron microscopy and the ultrastructure of the cells was compared. Annulate lamellae (AL) were observed in small amounts in both control and antitubulin-treated cells. The amount of AL did not markedly differ in the control versus antitubulin-treated cells. Furthermore, few multinucleated cells were observed in antitubulin-treated cultures. These results indicate that prolonged culture of cells in antitubulins need not, in itself, lead to a condition of enhanced AL development as reported in several other studies using various cell types.

Abstract
The fine structure of alpha L929 fibroblasts cultured in colchicine or vinblastine sulfate for periods as long as 48 hr was compared to control cells not exposed to antitubulins . In response to prolonged antitubulin culture, several changes in cell ultrastructure were noted: Control fibroblasts contain cytoplasmic annulate lamellae (AL), but prolonged exposure to either vinblastine sulfate or colchicine results in enhanced development of AL. Single pore complexes are present in the rough-surfaced endoplasmic reticulum (rER) in both control and antitubulin-treated cells, but stacked porous cytomembranes also occur under both conditions. Polyribosomes often are closely associated or continuous with the pore complexes. Many antitubulin-treated cells become multinucleate. Some nuclei in both control and antitubulin-treated cells contain large and multiple nucleoli. The large and multiple nucleoli are either attached directly to the inner membrane of the nuclear envelope or to infoldings of the nuclear envelope. Antitubulin-treated cells, after 48-hr exposure, appear also to contain enhanced quantities of smooth-surfaced endoplasmic reticulum (sER) and cytoplasmic filaments (and in some cells, lysosomes and rER as well) when compared to untreated cells. In both control and colchicine-treated cells, AL can exhibit continuity with either rER or sER. Further, all three membrane systems may at times be continuous, but the quantity of these membranes appears to be greater in colchicine-treated cells than in control cells. The results are discussed with respect to possible functional significance.

Abstract
The nuclear envelope (NE) is the interface of the two major compartments of the cell. We used differential solubilization in conjunction with ultrastructural visualization to localize components of the NE in the surf clam Spisula solidissima. The high salt-resistant NE fraction can be separated into a pore complex-containing supernatant (4 M urea extract) and a membrane pellet devoid of pore complexes or pore remnants. Urea extraction of the membrane pellet reveals two major proteins with an apparent molecular weight (MWapp) of 67 000 (clam lamin) and 200 000 that are also found in the high-salt and detergent-extracted NE containing pore complexes. Urea extraction of the clam NE under reducing conditions removes the clam lamin. The 200 000 D protein remaining in the NE after removal of the pore complex is not solubilized by detergent extraction and thus can be localized on the inner nuclear part of the NE.
