A Quote by Torsten Wiesel

In the early Sixties, having begun to describe the physiology of cells in the adult cat visual cortex, David Hubel and I decided to investigate how the highly specific response properties of cortical cells emerged during postnatal development.

Innate mechanisms endow the visual system with highly specific connections, but visual experience early in life is necessary for their maintenance and full development. Deprivation experiments demonstrate that neural connections can be modulated by environmental influences during a critical period of postnatal development.

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.

Thomas R. Insel

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.

David Baltimore

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.

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.

There are two main types of immunity to an infection. Innate immunity comes from circulating cells that attack any invader the body views as foreign. Adaptive immunity is specific to the pathogen presented. Through adaptive response, immune cells are programmed to secrete antibodies that are primed to target a viral invader.

Scott Gottlieb

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.

Judith E. Glaser

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.

Bruce Lipton

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.

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.

Jim Ryun

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.

Eliot Engel

The brain is a tissue. It is a complicated, intricately woven tissue, like nothing else we know of in the universe, but it is composed of cells, as any tissue is. They are, to be sure, highly specialized cells, but they function according to the laws that govern any other cells. Their electrical and chemical signals can be detected, recorded and interpreted and their chemicals can be identified; the connections that constitute the brain's woven feltwork can be mapped. In short, the brain can be studied, just as the kidney can.

David H. Hubel

So why in the world would anyone support the unethical, failed use of embryonic stem cells instead of the ethical, successful use of adult stem cells? Because they do not know the difference.

Virginia Foxx

Using adult stem cells drawn from bone marrow and umbilical cord blood system cells, scientists have discovered new treatments for scores of diseases and conditions such as Parkinson's disease, juvenile diabetes, and spinal cord injuries.

People lose fifty million skin cells every day. The cells get scraped off and turn into invisible dust, and disappear into the air. Maybe we are nothing but skin cells as far as the world is concerned.

Haruki Murakami

It is unlikely that changes in telomeres are influencing the lifespan of the worm. That is because telomeres only shorten when cells divide. Most of the cells of the worm stop dividing when the worm becomes an adult.
