While this research has been extremely useful there is a finite amount we can learn about cytokinesis in isolated cells. For a multicellular being the moments after the first division provide a new challenge, a neighboring cell! Most of the human cells that divide in our body have many neighboring cells, not just one, this posses all sorts of obstacles for a dividing cell. How does the dividing cell overcome the resistive forces of neighboring cells? Do neighboring cells assist with cell division? How does the tissue maintain its barrier functions as cells within it divide? Chapter two of my dissertation aims to answer several of these questions.
