Genome complexity:midbodies (Introduction)

What is left when two cells divide is a midbody which goes to one cell only, and we still don't know why, but it makes each cell not really twins, like was thought for ages.-"Regardless of its role in development, there seems to be agreement now among cell biologists that the midbody is important for the cell. Additionally, midbody retention delegitimizes an assumption to which most biologists ascribed for decades: that daughter cells are essentially the same, receiving equal contributions from the parent cell. "When you say that cells are identical when they're divided, it's not true," says Doxsey: the cell that internalizes the midbody carries hundreds of proteins that its sister does not.
 
What exactly this means to the cell, however, remains to be seen. Midbodies "could be completely irrelevant," Mitchison says, "or they could be doing something interesting.' "-
