Cells in sentence

1993 examples of Cells in a sentence

Today we realize that there are many different types of stem cells.
Fat-derived stem cells are adult stem cells.
And as it turns out, fat is one of the best sources of adult stem cells.
But adult stem cells are not embryonic stem cells.
And here is the limitation: adult stem cells are mature cells, and, like mature human beings, these cells are more restricted in their thought and more restricted in their behavior and are unable to give rise to the wide variety of specialized cell types, as embryonic stem cells [can].
They discovered that adult cells, taken from you and me, could be reprogrammed back into embryonic-like cells, which they termed IPS cells, or induced pluripotent stem cells.
Indeed, there is a lot of hype, but also hope that the promise of stem cells will one day provide cures for a whole range of conditions.
As the world population ages, scientists are racing to discover new ways to enhance the power of the body to heal itself through stem cells.
It is a fact that when our organs or tissues are injured, our bone marrow releases stem cells into our circulation.
And these stem cells then float in the bloodstream and hone in to damaged organs to release growth factors to repair the damaged tissue.
Stem cells may be used as building blocks to repair damaged scaffolds within our body, or to provide new liver cells to repair damaged liver.
As we speak, there are 117 or so clinical trials researching the use of stem cells for liver diseases.
Stem cells may be used to deliver growth factors to repair damaged heart muscle or be differentiated into heart muscle cells to restore heart function.
There are 170 clinical trials investigating the role of stem cells in heart disease.
While still in a research phase, stem cells may one day herald a quantum leap in the field of cardiology.
And in the U.K., neural stem cells to treat stroke are being investigated in a phase one trial.
It may seem like we're quite remote from other parts of this tree of life, but actually, for the most part, the basic machinery of our cells is pretty much the same.
And speaking of bacteria, do you realize that each of us carries in our gut more bacteria than there are cells in the rest of our body?
I became enamored of the power of evolution, and I realized something very fundamental: in most of the existence of life in single-celled organisms, each cell simply divides, and all of the genetic energy of that cell is carried on in both daughter cells.
Believe it or not, there's an experimental trial going on with vaccine against influenza that has been grown in the cells of a tobacco plant.
You can change the cells in your body, but what if you could change the cells in your offspring?
So something I think is very fascinating is: What if you could give life to non-living structures, like batteries and like solar cells?
The last example are solar cells.
You can also do this with solar cells.
And what we've found is through genetic engineering, we can actually increase the efficiencies of these solar cells to record numbers for these types of dye-sensitized systems.
And they've told us that this brain is an incredibly complicated circuit made out of hundreds of billions of cells called neurons.
Now, unlike a human-designed computer, where there's a fairly small number of different parts, and we know how they work because we humans designed them, the brain is made out of thousands of different kinds of cells, maybe tens of thousands.
There's a class of cells, a fairly small cell, an inhibitory cell, that quiets its neighbors.
It's one of the cells that seems to be atrophied in disorders like schizophrenia.
As just a second example: these pyramidal cells, large cells, can span a significant fraction of the brain.
