Furrow formation in cytokinesis

WebA new paper on cytokinesis in Chlamydomonas has been published in PNAS. In this paper, we demonstrated that F-actin is enriched in the cleavege-furrow region of dividing Chlamydomonas cells by using Lifeact marker. Interestingly, however, there is no myosin co-localizing with F-actin in the furrow, suggesting that no “actomyosin” structure ... WebOct 4, 2024 · Cytokinesis Definition. Cytokinesis is the final process in eukaryotic cell division, which divides the cytoplasm, organelles, and cellular membrane. Cytokinesis typically occurs at the end of mitosis, after telophase, but the two are independent …
