Cell Differentiation Quotes & Sayings

The importance of the egg's non-nuclear material - the cytoplasm - in early development is apparent in the consistent relation that is seen to exist between certain regions in the cytoplasm of a fertilized egg and certain kinds or directions of cell differentiation. — John Gurdon

Cell differentiation can turn neurons into everything from clocks that control circadian rhythms to photoreceptors that convert light into electrical-chemical impulses or decision makers that tally votes and decide courses of action. In the retina (often used as a case study because it can be directly and naturally stimulated), there are at least fifty different kinds of neurons specialized to different tasks, such as looking for motion, recognizing colors, detecting objects in low light, and measuring brightness and contrast. In the brain as a whole, there may be as many as 10,000 different kinds of neurons, each contributing to a different aspect of mental life. — Gary F. Marcus

Until you believe you can do it, it's going to be difficult to convince anyone else you can do it. — Toni Sorenson

You are 100 percent certain that this person is doing the best he can?" After I answered yes two or three times, the officer took a deep breath and said, "Then move the rock." I was confused. "What do you mean by 'move the rock'?" He shook his head. "I have to stop kicking the rock. I need to move it. It's hurting both of us. He's not the right person for this position, and there's no amount of pushing or getting on him that's going to change that. He needs to be reassigned to a position where he can make a contribution. — Brene Brown

Indeed, there is a school of thought that any work on a branch is, in the lean sense, waste - inventory that is not being pulled into the finished product. — David Farley

I think a lot of people have an idealistic view - if you grow up in the country, there can't possibly be anything wrong with you. — PJ Harvey

We draw our strength from the great oaks of the forest. As they take their nourishment from the soil, and from the rains that feed the soil, so we find our courage in the pattern of living things around us. They stand through storm and tempest. They grow and renew themselves. Like a grove of young oaks, we remain strong. — Juliet Marillier

It feels like home, far from home, yet homely. I have always been a fan of Delhi's practical life not that i have lived in an aspiration or yearning to make a living here, but delhi has always been on my soapbox. — Parul Wadhwa

As with most animal eggs, the early events of amphibian development are largely independent of the environment, and the processes leading to cell differentiation must involve a redistribution and interaction of constituents already present in the fertilized egg. — John Gurdon

The religion of reason quite naturally establishes the Republic of law and order. The general will is
expressed in laws codified by its representatives. "The people make the revolution, the legislator makes
the Republic." "Immortal, impassive" institutions, "sheltered from the temerity of man," will govern in
their turn the lives of all men by universal accord and without possibility of contradiction since by
obeying the laws all will only be obeying themselves — Albert Camus

Why incentivize laziness? High-school students shouldn't be discouraged from grappling, sometimes unsuccessfully, with challenging books, pictures, and songs. A really, really good work of art doesn't bow down to you; you step up to it, and it rewards you. In the end, kids faced with what Chaucer actually wrote may still dislike him, and I'm fine with that; they will have earned that opinion rather than had it handed to them. For heaven's sake, it's easy for kids to see themselves and their peers in a rap song. When they can start to see themselves in a 14th-century poem, then they're actually learning something. — Jeff Sypeck

When you love people like Jesus, you get messy. But messy looks good on you! — Bob Goff

I'd said to them that when we read fiction, we pour our own paricular store of emotions - say, the sense of loss we feel for those disappeared from our lives - into the characters set before us. We take the few words with which the writer sketches these characters, the thing he said, the pain she felt, where they were, and our own emotional stockpile magically creates people. As the human eye fleshes out the pixilated image. Fictional characters are highly sophiticated Rorschach blots, and we, along with their author, are their authors. When you read a fictional character, you too are creating her. — Chandler Burr

She fell into the moody, miserable state of mind which often comes when strong wills have to yield to the inevitable. — Louisa May Alcott

On the whole, at least in the author's experience, the preparation of species-specific antiserum fractions and the differentiation of closely related species with precipitin sera for serum proteins does not succeed so regularly as with agglutinins and lysins for blood cells. This may be due to the fact that in the evolutional scale the proteins undergo continuous variations whereas cell antigens are subject to sudden changes not linked by intermediary stages. — Karl Landsteiner

addition to the major types of cell that result from differentiation, similar processes can also alter the phenotype of terminally differentiated cells to subtly alter their functions. These different programmes of gene expression are often referred to as altered states of activation, or polarisation. — Clett Erridge

My sister was a twin, and the other baby died in childbirth, and I was three at the time, and I always kind of thought it haunted me. It was a weird thing. My dad was an ob-gyn, and so it was confusing that the other baby didn't come home from the hospital. — Scott Turow

The Doctor: [aiming gun at the ceiling] Didn't anyone ever tell you? There's one thing you never put in a trap if you're smart. If you value your continued existence, if you have any plans about seeing tomorrow, there's one thing you never, ever put in a trap.
Angel Bob: And what would that be, sir?
The Doctor: Me. [fires] — Steven Moffat

...But you, Lance, you've always needed someone special. And...I knew it was right when I met Tim. He needs you too, so much."

Lance just looked at her helplessly, unable to say anything.

"Oh, my dear son." She squeezed his hands. "He makes you dance. — Eli Easton
