Cervical cancer cells dividing, coloured scanning electron micrograph (SEM). The cervix is the lower part of the womb, also called the neck of the womb and comprises part of the woman掇 reproductive system. Cervical cancer is more common in younger women and one of the main causes is a persistent infection of certain types of the human papilloma virus (HPV). In this image the cells are undergoing cytokinesis which is the physical process of cell division which divides the parental cell into two daughter cells. Cancer cells often divide and multiply uncontrollably which can lead to the formation of tumours. At the end of cytokinesis, the two daughter cells remain connected by the midbody for a short time. The midbody is organised by a set of microtubules and its main function is to localize the site of natural detachment (abscission) between the two daughter cells.
