Cleavage furrow positioning in dividing Dictyostelium cells
Cytoskeleton, 2023AbstractAccurate placement of the cleavage furrow is crucial for successful cell division. Recent advancements have revealed that diverse mechanisms have evolved across different branches of the phylogenetic tree. Here, we employed Dictyostelium cells to validate previous models.

Cleavage Furrow Organization Requires PIP2-Mediated Recruitment of Anillin [PDF]
Current Biology, 2012 Cell division is achieved by a plasma membrane furrow that must ingress between the segregating chromosomes during anaphase [1-3]. The force that drives furrow ingression is generated by the actomyosin cytoskeleton, which is linked to the membrane by an as yet undefined molecular mechanism. A key component of the membrane furrow is anillin.

Cleavage furrow: Calcium as determinant of site
Experimental Cell Research, 1972Abstract Direct application of EDTA at precise locations on the cortex at different times during the division of sea urchin eggs was accomplished with a capillary filled with agar-EDTA using a micromanipulator. Treatment with EDTA prior to mid-metaphase arrested cleavage irreversibly. The effects of EDTA applications during metaphase varied according

Establishment of cleavage furrows by the mitotic spindle
Journal of Experimental Zoology, 1974AbstractThe purpose of this investigation was to determine the capacity for furrow establishment of the mitotic spindle in several kinds of dividing animal cells. To this end the cell shape was altered so that equatorial surface was brought in contact with the spindle and its normal geometrical relation with the asters changed. In flattened Tripneustes

Site selection for the cleavage furrow at cytokinesis
Trends in Cell Biology, 2005The question of how the site for division of the cytoplasm is determined at the end of mitosis has been studied for over a century, and it remains an active, controversial and fascinating problem in cell biology. This problem draws on the use of several model cell types, with the goal of understanding and identifying how the cell cycle regulates ...

Experiments concerning the cleavage furrow in invertebrate eggs
Journal of Experimental Zoology, 1966AbstractDividing eggs of Echinarachnius parma, Hydractinia echinata, Cerebratulus fuscus and Mytilus edulis were subjected to experiments designed to yield additional information concerning the cytoplasm in the cleavage plane. Answers to the following questions were sought: (1) Will the base of the furrow cut itself upon a needle placed in its path at ...

Journal of Biochemistry, 1997
We have developed a method for the isolation of cleavage furrows from dividing sea urchin eggs, which is applicable to various sea urchin species. The new method differs from that used for isolating cleavage furrows from sand dollar Clypeaster japonicus eggs [Yonemura, S., Mabuchi, I., and Tsukita, S. (1991) J. Cell Sci.

The STE group kinase SepA controls cleavage furrow formation in Dictyostelium
Cell Motility, 2009AbstractDuring a REMI screen for proteins regulating cytokinesis in Dictyostelium discoideum we isolated a mutant forming multinucleate cells. The gene affected in this mutant encoded a kinase, SepA, which is an ortholog of Cdc7, a serine‐threonine kinase essential for septum formation in Schizosaccharomyces pombe.

Electron microscopy of early cleavage furrows in the chick blastodisc
Journal of Ultrastructure Research, 1974Cleavage furrows from two, four, and eight-cell chick embryos were studied by light and electron microscopy. In medial transverse section furrows were either V-, U-, or pendulum-shaped. Glycogen-filled surface folds were present along the furrow edge of V- and U-shaped furrows.
