Cell Development Quotes

I may be the only person in the world who has my own embryonic cells growing in a petri dish.

The nucleic acids have considerable biological importance because of their role in cell growth and in the transmission of hereditary characters.

A key issue in developmental biology at that time was the problem of how cells underwent differentiation, with most workers concentrating on explanations in terms of changes in enzyme and gene regulation.

Well, there are two kinds of stem cells: adult stem cells, which you can get from any part of a grown body, and embryonic stem cells. These are the inner- core of days-old embryos that can develop into any kind of cell.

It is easy to make out three areas where scientists will be concentrating their efforts in the coming decades. One is in physics, where leading theorists are striving, with the help of experimentalists, to devise a single mathematical theory that embraces all the basic phenomena of matter and energy. The other two are in biology. Biologists-and the rest of us too-would like to know how the brain works and how a single cell, the fertilized egg cell, develops into an entire organism

Stem cells are like toenail clippings with a better career plan.

If stem cells divide equally, so both daughter cells look more or less the same, each one becomes another stem cell. If the split is unequal, neurons form prematurely.

Biology is far from understanding exactly how a single cell develops into a baby, but research suggests that human development can ultimately be explained in terms of biochemistry and molecular biology. Most scientists would make a similar statement about evolution.

And right now I may just be living inside the heart of the body, and I one day hope to move to the brain.

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.

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.

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.

Pluripotent cells have the ability to grow into any cell in the body.

I am interested in how cells know what they are and how they should behave in their proper place in the body.

Nearly every one of the genes that turns out to be a key player in cancer has a vital role in the normal physiology of an organism. The genes that enable our brains and blood cells to develop are implicated in cancer.

Scientists have stated that embryonic stem cells provide the best opportunity for devising unique treatments of these serious diseases since, unlike adult stem cells, they may be induced to develop into any type of cell.

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.

Heredity is to-day the central problem of biology. This problem may be approached from many sides—that of the breeder, the experimenter, the statistician, the physiologist, the embryologist, the cytologist—but the mechanism of heredity can be studied best by the investigation of the germ cells and their development.
