Factors that initiate cell division
WebIn contrast, muscle cells can grow to very large sizes without undergoing cell division. Whether cell growth and cell division are coordinated seems to depend upon the wiring of the mitogen and growth factor signaling pathways. In some cells, mitogens or growth factors activate both cell growth and cell division, suggesting that there is ... Webthe cell cycle. For example, a cell that is surrounded by other cells stops dividing. Many cells also release chemical signals that tell other cells to grow.
