Myosin-null cells are able to divide on an adhesive surface, such as glass. (A) Cells expressing GFP-myosin are able to divide on a glass surface successfully. Times of the panels are 0, 50, 100, 160, 220, and 350 s. (B) Myosin-null cells can undergo mitosis-coupled division with morphologies similar to cells expressing functional myosin. Times of the panels are 0, 60, 170, 260, 350, and 430 s. (C) However, sometimes the cleavage furrow is not centered, resulting in unequal daughter cells. Times of the panels are 0, 200, 450, 710, 950, and 1000 s. Bar, 5 μm.
