We have 200 trillion cells, and the outcome of each of them is almost 100 percent genetically determined. And that's what our experiment with the first synthetic genome proves, at least in the case of really simple bacteria. It's the interactions of all those separate genetic units that give us the physiology that we see.
When you think of all the things that are made from oil or in the chemical industry, if in the future we could find cells to replace most of those processes, the ideal way would be to do it by direct design.
IPS cells can become a powerful tool to develop new drugs to cure intractable diseases because they can be made from patients' somatic cells.
What seems to be clear to me is that after the primary infection most of the cells die indirectly, but at the later stage, when the viral load is very high, the virus kills a lot of cells directly.
Although each egg cell produced by a woman carries a single X chromosome, the sperm cells produced by a man carry either an X or a Y. This means, in very simple terms, that the sperm cell determines a baby's sex.

We keep thinking that the human is evolving. No, the human has evolved to its extent. What's happening now is the organization of humans: just like cells organize to form people, people are organizing to form humanity.
I was working with stem cells as part of a NASA programme. We realised that the science of stem-cell proliferation was also fundamental to cancer cells when cancer enters the phase of metastasis.
There are no bona fide treatments available for embryonic stem cells. There is nothing in the laboratory, and there is certainly nothing in the clinics available to patients.
Your cells are not working as hard as your dog's but harder than your horse's. The bigger the animal, the less energy needed to sustain a gram of tissue.
In my lab, we are always thinking about how cells, bacterial cells, can talk to each other and then organize themselves into enormous groups that function in unison.
A meticulous virtual copy of the human brain would enable basic research on brain cells and circuits or computer-based drug trials.
Battering down solar cells on the roofs of Wal-Marts in California. I think that will be some of the highest-return investments that anyone ever makes.
Babies have millions of brain cells. They are like light bulbs waiting to be turned on. Don't wait for them to go to school and hope for the best.
I've been thinking about the record since I reached the fifty plateau. But you think about it and then you let it go because you can't waste many brain cells on hours thinking about it.
So why in the world would anyone support the unethical, failed use of embryonic stem cells instead of the ethical, successful use of adult stem cells? Because they do not know the difference.
The cell is a city of production centres, each part working away like mad, and it's co-ordinated. Six trillion cells in a body - you can't help but be moved.
Water is commonly regarded as the 'solvent of life,' since our bodies are 70% water. All other vertebrates, invertebrates, microbes, and plants are also primarily water. The organization of water within biological compartments is fundamental to life, and the aquaporins serve as the plumbing systems for cells.
The Stem Cell Research Enhancement Act would expand research on embryonic stem cells by increasing the number of lines stem cells that would be eligible for federally funded research.
Al-Qaeda has a kind of loose, almost entrepreneurial structure with lots of cells in various countries that are semi-independent.
Where he was, where his cells were, where his logistical channels were, how he communicated. Who his allies were. Who donated to them. I think it's fair to say the entire range of sources were brought to bear.
Adult stem cells are also problematic, as they are difficult to identify, purify and grow, and simply may not exist for certain diseased tissues that need to be replaced.
Stem cells are probably going to be extremely useful.
We know specific genes are turned on in specific cells, but we don't know to what extent this happens.
I learned about HeLa cells in my first basic biology class, and I just became completely obsessed with them from that point on.
The laws are still very unclear. Cells are still taken from people without consent - a lot of people don't realize it.
