A Quote by John Gurdon
Once the principle is there, that cells have the same genes, my own personal belief is that we will, in the end, understand everything about how cells actually work.

We know cancer is caused ultimately via a link between the environment and genes. There are genes inside cells that tell cells to grow and the same genes tell cells to stop growing. When you deregulate these genes, you unleash cancer. Now, what disrupts these genes? Mutations.
Most of our brain cells are glial cells, once thought to be mere support cells, but now understood as having a critical role in brain function. Glial cells in the human brain are markedly different from glial cells in other brains, suggesting that they may be important in the evolution of brain function.
When we talk about stem cells, we are actually talking about a complicated series of things, including adult stem cells which are largely cells devoted to replacing individual tissues like blood elements or liver or even the brain.
Trying to understand fundamental processes that take place as organisms develop and how their various cells interact with one another - one can see what happens with those cells by asking questions about the fundamentals of biology.
Conversational intelligence is hard-wired into every single human-being's cells. It's the way the cells engage with each other. Believe it or not, cells talk to each other. The immune system talks to the cells.
Cancer is really a DNA disease... We have these certain genes that prevent our cells from growing out of control at the expense of the body. And it's a pretty good, robust system. But if a couple of these genes fail, then that's when cancer starts, and cells start growing out of control.
One of the first papers I wrote at the University of Wisconsin, in 1977, was on stem cells. I realized that if I changed the environment that these cells were in, I could turn the cells into bone, and if I changed the environment a bit more, they would form fat cells.
The elementary parts of all tissues are formed of cells in an analogous, though very diversified manner, so that it may be asserted, that there is one universal principle of development for the elementary parts of organisms, however different, and that this principle is the formation of cells.
Each of our cells is a living entity, and the main thing that influences them is our blood. If I open my eyes in the morning and my beautiful partner is in front of me, my perception causes a release of oxytocin, dopamine, growth hormones - all of which encourage the growth and health of my cells. But if I see a saber tooth tiger, I'm going to release stress hormones which change the cells to a protection mode. People need to realize that their thoughts are more primary than their genes, because the environment, which is influenced by our thoughts, controls the genes.
What do cells do when they see a broken piece of DNA? Cells don't like such breaks. They'll do pretty much anything they can to fix things up. If a chromosome is broken, the cells will repair the break using an intact chromosome.
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.
I believe fuel cells will finally end the 100-year reign of the internal combustion engine. . . Fuel cells could be the predominant automotive power source in 25 years.
As was predicted at the beginning of the Human Genome Project, getting the sequence will be the easy part as only technical issues are involved. The hard part will be finding out what it means, because this poses intellectual problems of how to understand the participation of the genes in the functions of living cells.
Both in Britain and America, huge publicity has been given to stem cells, particularly embryonic stem cells, and the potential they offer. Of course, the study of stem cells is one of the most exciting areas in biology, but I think it is unlikely that embryonic stem cells are likely to be useful in healthcare for a long time.
It turns out that the very genes that turn on in cancer cells perform vital functions in normal cells. In other words, the very genes that allow our embryos to grow or our brains to grow, our bodies to grow, if you mutate them, if you distort them, then you unleash cancer.
Borna virus is not a retrovirus. It doesn't actually insert its own genes into our cells. What it does is just hangs out near our DNA and uses some of the molecular machinery to copy itself.
