In regular cells like ordsprog

In regular cells, like in bone and blood, the cells divide. But brain cells do not normally divide. The great majority will not divide. The neurons you're born with are pretty much what you have at end of life.

Most of the tissues that age ... that we're interested in -- the brain, the heart, the muscle, the kidney, etc. -- those cells never divide at all and they never replicate their nuclear DNA so their telomeres can't get shorter and, therefore, that couldn't affect their longevity,

We set out to find whether these cells would be able to respond to the injury in an appropriate and beneficial way on their own, ... We were excited to find that the cells responded to the damage by making appropriate new cells that could assist in repair. This study supports the possibility that formation of new myelin and new neurons may contribute to recovery.

How does the primary tumor cause the bone marrow cells to settle somewhere and provide a fertile field for metastasis - does it send out chemicals that stimulate the bone marrow cells? And why do those bone marrow cells settle where they do? It also opens possibilities for other avenues of attack against the cancer to prevent its spread. Before anything else, however, other researchers need to confirm that these findings are true.

They'll have their own bone marrow harvested. Stem cells will come over to this new facility and processed for a purified layer of cells containing stem cells. We'll put them directly into the heart during the operation.

We found they could be induced to mature into nerve cells, hair follicles, muscle cells and gut endoderm cells. And when cultured in lab dishes, the cells differentiated, or matured, into the three major basic types of cell.

We speculate that our brains can compensate for up to a 60 percent loss of pre-Boetzinger cells, but the cumulative deficit of these brain cells eventually disrupts our breathing during sleep. There's no biological reason for the body to maintain these cells beyond the average lifespan, and so they do not replenish as we age,

This is a very important clue, because it indicates this program of fat storage is perpetuated as these cells divide. It's not driven strictly by over-nutrition.

The adhesion of cells is very quick and far stronger than will be needed for most applications. We just let them incubate for 35 minutes, rinse, and we're ready to go. We've kept our cells alive on the chip for up to 25 hours and the same proportion of cells survive using our method as cells cultured under identical conditions.

They are so rare in number. We are talking about, in typical blood that may have over a billion cells in it, we may find only 200 to 1,000 of these cells in that billion cells. So I believe that's why other groups have not found them yet,

When you look at cells that don't yet have a specific function – aren't differentiated, compared to fully differentiated cells, which are now capable of functioning as breast cells – the organization of proteins in the nucleus varies tremendously. Then looking at how the proteins in malignant cells are distributed, it's a totally different pattern compared to normal differentiated cells.

They try to divide you, all these guys try to divide you and they try to divide the team. They get an unnamed source or a player here (to say) that we're all pointing fingers.

Hubie Brown (1933-)

You can divide neighborhoods, you can divide houses, you can probably divide double beds if you want, to get down to people's voting preferences.
