One research group [led by a former student] made mice with adult brain cells and forced them with a viral gene to turn on cell - division machinery.

The whole process is reminiscent of trial - and - error learning in which each cell explores — at its own rhythm and independently of cell division — different molecular possibilities (i.e. different genes turned on or off) before reaching a stable combination of active genes and the corresponding morphology.

The egg's very structure, its scaffolding of proteins that guide the chromosomes during cell division, may also play a key role in turning on the necessary genes.

For example, a gene called p53, which normally acts as a brake on cell division, turns out to be mutated or lost in about half of all tumours.

As a powerful tumor suppressor, p53 turns on genes that either halt cell division to allow time for repair of damaged DNA or, when all rescue attempts prove futile, to prevent cells with genetic defects from dividing, as this would fuel the development of cancer.

Five studies conducted on 4,443 breast cancer survivors over a period of nine years found that the benefits of vitamin D help to increase communication between cells by turning on a protein that blocks cells division.
