Quotes About Cells

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.

Touch' is a multi-faceted concept, reflecting the different types of receptors. The simplest are free nerve endings which detect pain and changes in temperature; slightly more complex are Merkel's tactile cells (which detect pressure); followed by Grandry bodies, which consist of two to four tactile cells and detect movement (velocity); and the lamellated Herbst corpuscles (similar to Vater-Pacinian corpuscles in mammals), which are sensitive to acceleration.

Magnetic sensations are different because, unlike light and sound, they can pass through body tissues. This means that it is possible for a bird (or other organism) to detect magnetic fields via chemical reactions inside individual cells throughout its entire body.

A lot of the data we collect is stuff that has to be analyzed on the ground. For instance, we can't see, you know, bone loss. Our cells, you know, that's something that we'll have to notice with imaging technology when I get back.

By weight, you are more human than bacteria, because your cells are bigger, but by numbers, it's not even close.

I learned about HeLa cells in my first basic biology class, and I just became completely obsessed with them from that point on.

Within six months of starting my Ph.D. work in 1956, I had already obtained feeding tadpoles derived from transplanted nuclei of embryonic cells.

Life is not governed by will or intention. Life is a question of nerves, and fibres, and slowly built-up cells in which thought hides itself and passion has its dreams. You may fancy yourself safe, and think yourself strong. But a chance tone of colour in a room or a morning sky, a particular perfume that you had once loved and that brings sublte memories with it, a line from a piece of music that you had ceased to play--I tell you Dorian, that it is on things like these that our lives depend.

Life is not governed by will or intention. Life is a question of nerves, and fibres, and slowly built-up cells in which thought hides itself and passion has its dreams.

You and I are cobbled out of carbon cells that were once other things entirely. We could have a carbon cell in one of our elbows that was once part of a trilobite's tail. Or a cell from Atilla the Hun's moustache in our eye. Or an ancient lotus petal in our tonsils.

Instead of injecting a weakened or partial version of the dangerous virus into humans, these new vaccines deliver a gene or piece of genetic coding that will guide human cells to produce, on their own, components of the virus.

RNA (ribonucleic acid) is a molecule in living cells that is similar to DNA (deoxyribonucleic acid), but it has one more oxygen atom in its sugar-phosphate backbone and a difference in one of its four bases.

DNA doesn't do much work. It mainly stays at home in the nucleus of our cells, not venturing forth. Its primary activity is protecting the information it encodes and occasionally replicating itself.

These proteins come in many types. Fibrous proteins, for example, form structures such as bones, tissues, muscles, hair, fingernails, tendons, and skin cells. Membrane proteins relay signals within cells. Above all is the most fascinating type of proteins: enzymes. They serve as catalysts. They spark and accelerate and modulate the chemical reactions in all living things. Almost every action that takes place in a cell needs to be catalyzed by an enzyme. Pay attention to enzymes

Genetic vaccines The plague year of 2020 is likely to be remembered as the time when these traditional vaccines began to be supplanted by genetic vaccines. Instead of injecting a weakened or partial version of the dangerous virus into humans, these new vaccines deliver a gene or piece of genetic coding that will guide human cells to produce, on their own, components of the virus. The goal is for these components to stimulate the patient's immune system.

Bad information is a disease that attacks the brain. It messes with your head, making you do things that you shouldn't, causing you to make wrong decisions. Just as a potent virus co-opts your cells' machinery, bad information can co-opt your behavior. It can alter the way you interact with the world and, as a result, it can change the world.

We're all one thing, like cells in a body. 'Cept we can't see the body. The way fish can't see the ocean. And so we envy each other. Hurt each other. Hate each other. How silly is that? A heart cell hating a lung cell.

If you have more glucose in your body than your cells need, insulin takes extra blood glucose and transports it into fat storage. Blood sugar then returns to normal. This step is important because having abnormally high levels of blood glucose is called diabetes and is very damaging to the body.

The moment we crossed over the threshold, the moment when our veins and cells and organs went blip, I closed my eyes And illusioned. It wasn't like any illusion I'd created before. It flowed from me like a song, an orchestra of interweaving threads and melodies, painting themselves into a picture around us. [Everything] ... disappeared, and only Constantine, Queen Honoria and I stood in the nothing between two worlds.

It was as if those school years bred a nostalgia so deep into the cells that the body woke to it each fall as naturally as the squirrels in the park began their frenzied harvest, never mind the weather was still fine, the sun still gracing them all.

The drugs don't destroy brain cells so much as they . . . eat away at their souls, leave them empty and purposeless.

Here cells die and are replaced. Knowing their own indestructibility, the CU's within them simply change form, retaining however the identity of all the cells that they have been. (Intently:) While the cell dies physically, its inviolate nature is not betrayed. It is simply no longer physical. That kind of "death" is, then, natural in one way or another within your system.

Unlike the heart or kidney, which have a small, defined set of cell types, we still do not have a taxonomy of neurons, and neuroscientists still argue whether specific types of neurons are unique to humans. But there is no disputing that neurons are only about 10 percent of the cells in the human brain.
