A Quote by Dave Barry

...and suddenly it hits you: Human skin is actually made up of billions of tiny units of protoplasm, called "cells"! And what is even more interesting, the ones on the outside are all dying! This is a fact. Your skin is like an aggressive modern corporation, where the older veteran cells, who have finally worked their way to the top and obtained offices with nice views,are constantly being shoved out the window head first, without so much as a pension plan,by younger hotshot cells moving up from below.
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.
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.
Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.
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.
Odd to think that the piece of you I know best is already dead. The cells on the surface of your skin are thin and flat without the blood vessels or nerve endings. Dead cells, thickest on the palms of your hands and the soles of your feet.
What do cells do when they see a broken piece of DNA? Cells don't like such breaks. They'll do pretty much anything they can to fix things up. If a chromosome is broken, the cells will repair the break using an intact chromosome.
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.
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.
Throughout our lifetimes we are constantly regenerating new brain cells in the hippocampus, a process called neurogenesis. New stem cells are constantly being born in the hippocampus that ultimately differentiate into fully functional neurons.

Living in New York, there's so much pollution, it's really good to just give your skin a reboot and get off all those dead skin cells. Then, moisture is everything just because my skin gets dried out so much from putting on makeup and pulling it off all day that I love face masks.
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.
The most dangerous cancer cells are actually the ones that are more like stem cells, which have this ability to produce themselves over and over again. More and more cancer biologists say stem-cell-like cells in cancers are the most dangerous.
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.
Like Honeycrisp, SweeTango has much larger cells than other apples, and when you bite into it, the cells shatter rather than cleaving along the cell walls, as is the case with most popular apples. The bursting of the cells fills your mouth with juice. Chunks of SweeTango snap off in your mouth with a loud cracking sound.
The human brain is the last, and greatest, scientific frontier. It is truly an internal cosmos that lies contained within our skulls. The more than 100 billion nerve cells and trillion supporting cells that make up your brain and mine constitute the most elaborate structure in the known universe.
