\t\t\tStem cells are non-differentiated cells that, through a process of asymmetric cell division, produce two completely different cells: a stem cell that is identical to the original one and a differentiated cell with a specific function in the organism. This particular division strategy allows stem cells to self-renew, and also permits the production of large amounts of tissue during development or the regeneration of tissue that has been damaged. When this tightly regulated cell division process gets thrown off balance, tumors can form. Studies like this one may therefore be key to helping researchers understand the molecular basis of some human diseases. <\/p>\n

Before cells divide, the centrosomes – components that organise the cell skeleton – must, like DNA, duplicate so that each daughter cell may receive its own set. They replicate in such a way that they produce an older (“mother”) and a younger (“daughter”) set. “Other groups have shown that when centrosomes are removed from stem cells, these cells divide symmetrically and can produce tumours, and these results show that centrosomes play a crucial role in asymmetric division”, explains Januschke, a member of Gonz\u00e1lez team and first author of the study. <\/p>\n
