The main reason why people die of cancer is that the cancer cells spread to form daughter tumours, or metastases, in vital organs, such as the lungs and liver.

In fact, as with eukaryotic organisms, division of Caulobacter cells generates two different daughter cells, which can be easily separated.

This week, he and his colleagues report a potentially significant step toward that goal: a recipe that can turn human stem cells into functional pancreatic β cells — the cells that are destroyed by the body's own immune system in type 1 diabetes patients such as Melton's son and daughter.

An asymmetric cell division in non-stem cells can instead result in two daughter cells with very different fates, such as one large cell that reinitiates cell division prematurely and a much smaller cell that either grows very slowly or dies.

Although unequal division occurs among stem cells — allowing one daughter cell to remain a stem cell while the other matures into another cell type, such as a skin or muscle cell — the goal of a normal symmetric cell division is to generate identical daughter cells and increase cell number.

The oncogene was coupled with a fluorescent marker so that cells in which the oncogene was active could be easily identified, and as these cells proliferate, their «daughter» cells could also be tracked.

The researchers also found that another population known as progenitor cells — differentiated daughter cells of stem cells — started to behave like stem cells: They began to live much longer than their usual lifespan of a few days, and they could also generate mini-intestines when grown outside of the body.

In contrast to mouse vRGs, which produce 10 to 100 daughter cells during brain development, a single human oRG can produce thousands of daughter neurons, as well as glial cells — non-neuronal brain cells increasingly recognized as being responsible for a broad array of maintenance functions in the brain.

The efficient compaction of DNA during cellular division ensures equal distribution of DNA into daughter cells and prevents aneuploidy, which has been implicated as a major driver of tumor development.

Daughters of the small intestinal stem cells, the Paneth cells, serve as crypt niche cells by providing Wnt, Notch and EGF signals (30).

Numerous biochemical and structural changes occur throughout the cell as the microtubule - based spindle assembles and attaches to the condensed chromosomes, segregates them, and signals to the cell cortex to induce cleavage into two daughter cells through an actin - based contraction.

This division can be oriented, daughter cells can be pushed inside or outside as result of the mitotic spindle orientation, and asymmetric, daughter cells can acquire distinct components giving them different contractile properties.

As a stem cell divides, one daughter cell, called a gonialblast, moves out of the niche in an orderly fashion to generate mature sperm cells.
