We know specific genes are turned on in specific cells, but we don't know to what extent this happens.
In fact when you combine stem cell technology with the technology known as tissue engineering you can actually grow up entire organs, so as you suggest that sometime in the future you get in an auto accident and lose your kidney, we'd simply take a few skin cells and grow you up a new kidney. In fact this has already been done.
Is it absurd to imagine that our social behavior, from amoeba to man, is also planned and dictated, from stored information, by the cells? And that the time has come for men to be entrusted with the task, through heroic efforts, of bringing life to other worlds?
For scientists, growing cells took so much work that they couldn't get much research done. So the selling of cells was really just for the sake of science, and there weren't a lot of profits.
Al Qaeda has significance beyond its numbers, frankly. And so for us, our 24-hour-a-day objective is to seek out those al Qaeda cells. And, as we seek them out, to target them and eliminate them. And we're doing that 24 hours a day.
Man, like other organisms, is so perfectly coordinated that he may easily forget, whether awake or asleep, that he is a colony of cells in action, and that it is the cells which achieve, through him, what he has the illusion of accomplishing himself.
Marriage is a difficult project. When seven years have passed and all your body's cells have been replaced, you're meant to experience that seven-year itch.
The doctors realized in retrospect that even though most of these dead had also suffered from burns and blast effects, they had absorbed enough radiation to kill them. The rays simply destroyed body cells - caused their nuclei to degenerate and broke their walls.
Reticulocytes are terminally differentiating red blood cells that do not contain lysosome. Therefore, it was postulated that the degradation of hemoglobin in these cells is mediated by a non-lysosomal machinery.
Except for certain moments - when cells are dividing, for instance - chromosomes don't form compact, countable bodies inside cells. Instead, they unravel and flop about, which makes counting chromosomes a bit like counting strands of ramen in a bowl.
How great is the mystery of the first cells which were one day animated by the breath of our souls! How impossible to decipher the welding of successive influences in which we are forever incorporated! In each one of us, through matter, the whole history of the world is in part reflected.
I have always been interested - indeed, waylaid - by the leading edges of technology, even during my Ph.D. years when I pioneered (but did not publish) agarose gel electrophoresis for RNA fractionation. Also, much later, I was instrumental in showing that Green Fluorescent Protein and RNAi could be made to work in mammalian cells.
Ideas not coupled with action never become bigger than the brain cells they occupied.
Adult stem cells have shown great potential and have effectively helped patients. Another alternative is cord-blood stem cells. These are a neglected resource that could be used to treat a diverse body of people.
Shinya Yamanaka's work has involved mice and human cells, and advances the prospect of providing new cells or body parts for 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.
A battery by definition is a collection of cells. So the cell is a little can of chemicals. And the challenge is taking a very high-energy cell, and a large number of them, and combining them safely into a large battery.
In my second year, after moving to the Medical School, I began the courses of Anatomy and Physiology. I had begun to see that I was interested in cells and their functions.
I believe fuel cells could end the 100-year reign of the internal combustion engine.
Your brain forms roughly 10,000 new cells every day, but unless they hook up to preexisting cells with strong memories, they die. Serves them right.
I started stem cells when I wanted to find a cure for my mother, who I loved very much, and western medicine was not able to cure her. If I had discovered stem cells a year before, I think that she would still be here with me.
One day between takes on the 'Oz' set, I went into one of the cells and laid down and dozed off. When I woke up, I thought I was back in a federal pen. But I did my time, and today no one is more of a free man than Chuck Zito.
Traditional academic science describes human beings as highly developed animals and biological thinking machines. We appear to be Newtonian objects made of atoms, molecules, cells, tissues, and organs.
One can envisage taking cells from a patient with sickle-cell anaemia or an inherited blood disorder and using the Cas9 system to fix the underlying genetic cause of the disease by putting those cells back into the patient and allowing them to make copies of themselves to support the patient's blood.
If you want to help Africa, you should help them out of poverty, not try to build solar cells and windmills.
The laws are still very unclear. Cells are still taken from people without consent - a lot of people don't realize it.
When are we going to say cancer is cured? I'm not sure when that will happen, if that will happen because cancer is a very slippery disease and it involves a vast number of cells in the body and those cells are continually mutating.
The word 'insurgency' had connotations that really sent a shiver down the spine of folks in Washington, in the United States - for good reason, because it means this is something much bigger than just a few terrorist cells.
In the case of the stomach, however, the nerves of the glandular cells were always severed when constructing an artificially isolated pouch and this, naturally, affected the normal work of the stomach.
If I'd written all the truth I knew for the past ten years, about 600 people - including me - would be rotting in prison cells from Rio to Seattle today. Absolute truth is a very rare and dangerous commodity in the context of professional journalism.
The cells of an organism are nodes in a richly interwoven communications network, transmitting and receiving, coding and decoding. Evolution itself embodies an ongoing exchange of information between organism and environment.
My brain cells are dying in their trillions.
We must move away from our dependency on fossil fuels, and I am glad that GM has invested over $1 billion in hydrogen fuel cells cars to meet this goal.
Already from your own cells scientists can grow skin, cartilage, noses, blood vessels, bladders and windpipes. In the future, scientists will grow more complex organs, like livers and kidneys. The phrase 'organ failure' will disappear.
If you asked me what caused aging, I would say free radicals and molecules, which spontaneously shift and form and cause damage in all our cells and genes. The body usually repairs and replaces the damage in these genes. But as you get older, the aging clock turns down those defenses.
Stem cells have the potential to be used to treat and better understand some of the world's most deadly and disabling diseases.
