A Quote by Ronald Ross

Lately, however, on abandoning the brindled and grey mosquitos and commencing similar work on a new, brown species, of which I have as yet obtained very few individuals, I succeeded in finding in two of them certain remarkable and suspicious cells containing pigment identical in appearance to that of the parasite of malaria. As these cells appear to me to be very worthy of attention ... I think it would be advisable to place on record a brief description both of the cells and of the mosquitos.
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.
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.
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.
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.
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.
Cancer cells have a lot of other things that are really wrong with them, and we should never forget that these are cells that have become deaf to all the signals that the body sends out, such as you can multiply a certain amount, you can be in a certain place in the body, where to stay, where to move, and so on.
I started stem cells when I wanted to find a cure for my mother, who I loved very much, and western medicine was not able to cure her. If I had discovered stem cells a year before, I think that she would still be here with me.
Shinya Yamanaka's work has involved mice and human cells, and advances the prospect of providing new cells or body parts for patients.
What seems to be clear to me is that after the primary infection most of the cells die indirectly, but at the later stage, when the viral load is very high, the virus kills a lot of cells directly.
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.
I have recently observed and stated that the serum of normal people is capable of clumping the red cells of other healthy individuals... As commonly expressed, it can be said that in these cases at least two different kinds of agglutinins exist, one kind in A, the other in B, both together in C. The cells are naturally insensitive to the agglutinins in their own serum.
The elementary parts of all tissues are formed of cells in an analogous, though very diversified manner, so that it may be asserted, that there is one universal principle of development for the elementary parts of organisms, however different, and that this principle is the formation of cells.
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.
Your brain forms roughly 10,000 new cells every day, but unless they hook up to preexisting cells with strong memories, they die. Serves them right.
The parasite that causes malaria edges through the cells of the stomach wall of the mosquito and forms a cyst which grows and eventually bursts to release hundreds of sporozoites into the body cavity of the mosquito ... As far as we can tell, the parasite does not harm the mosquito ... It has always seemed to me, though, that these growing cysts ... must at least give the mosquito something corresponding to a stomach-ache.
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.
