A Quote by Virginia Foxx
A stem cell is essentially a blank cell capable of becoming another, more differentiated cell-type in the body, such as a skin cell, a muscle cell or a nerve cell.

In science there is something known as a stem cell. A stem cell is an undifferentiated cell which has not yet decided whether it's gonna be a cell of your brain or a cell of your heart or of your finger nail. But science is learning how to coax, how to manipulate, the raw material of life that we call stem cell to become any cell of the body. I think that God is the stem cell of the universe.
Cell genetics led us to investigate cell mechanics. Cell mechanics now compels us to infer the structures underlying it. In seeking the mechanism of heredity and variation we are thus discovering the molecular basis of growth and reproduction. The theory of the cell revealed the unity of living processes; the study of the cell is beginning to reveal their physical foundations.
Every cell in our body, whether it's a bacterial cell or a human cell, has a genome. You can extract that genome - it's kind of like a linear tape - and you can read it by a variety of methods. Similarly, like a string of letters that you can read, you can also change it. You can write, you can edit it, and then you can put it back in the cell.
In families you can find the source of every human drama. It is interesting because the cell of a society, the cell of a country, the cell of humanity - everything lies in the family.
Upon the union of the male germ cell with the female egg cell, a new cell is created which almost immediately splits into two parts. One of these grows rapidly, creating the human body of the individual with all its organs, and dies only with the individual.
The number of cells in our bodies is defined by an equilibrium of opposing forces: mitosis adds cells, while programmed cell death removes them. Just as too much cell division can lead to a pathological increase in cell number, so can too little cell death.
Embryonic stem-cell research requires the destruction of life to create a stem cell. That's why I think we've got to be very careful in balancing the ethics and the science.
There is a duality in recognising what an incredible disease it is - in terms of its origin, that it emerges out of a normal cell. It's a reminder of what a wonderful thing a normal cell is. In a very cold, scientific sense, I think a cancer cell is a kind of biological marvel.
With the advent of cell phones, especially with the very small microphone that attach to the cell phone itself, it's getting harder and harder I find, to differentiate between schizophrenics and people talking on a cell phone.
My main efforts focussed on trying to identify the rate controlling steps during the cell cycle. Crucial for this analysis were wee mutants that were advanced prematurely through the cell cycle and so divided at a reduced cell size.
Body: A cell state in which every cell is a citizen.
Cord blood stem cell units have been shown to be a suitable alternative to adult bone marrow for the treatment of many diseases, including sickle cell anemia.
Most of the scientific community believes that for the full potential of embryonic stem cell research to be reached, the number of cell lines readily available to scientists must increase.
Under current federal policy on human embryonic stem cell research, only those stem cell lines derived before August 9, 2001 are eligible for federally funded research.
Laura Bush went on national television during the week of my father's funeral and spoke out against embryonic stem cell research, pointing out that where Alzheimer's is concerned, we don't have proof that stem-cell treatment would be effective.
We have a lot to gain through furthering stem cell research, but medical breakthroughs should be fundamentally about saving, not destroying, human life. Therefore, I support stem cell research that does not destroy the embryo.
