What are stem cells?

Question

I have almost no idea at all what a stem cell is, but I have to do an essay on it. Please could someone explain in very simple words what a stem cell is and what use it has today. I already know it is unspecialised and may be used in the future to treat some diseases, but other than that, I need information. Please help me!

Answer 1

Okay, lets put it in english rather than these morons who just wiki'd 'stem cells'

Basically Speaking, a 'Stem Cell' is a blank cell. It has the functions of a cell that is in the body, but has no specific recognition. It has to be placed and fused with other cells to copy those characteristics. Think of it as White paint. it will stay white paint, but if you mix it with a different colour, it will change to be like the other colour. its pretty much a cell with no obdy information that has to be told what it is supposed to do.

Answer 2

plenty have already given the reason that it particularly is embryonic stem cellular learn that Catholics are against. it particularly is authentic. it is likewise substantial to notice that person stem cellular learn presently facilitates with the medical look after over 70 ailments. Embryonic stem cellular learn isn't almost as promising from what they have completed so far - it has produced 0 treatments. Why no longer positioned money into the approach it particularly is generating outcomes (person stem cells) rather of putting money right into a pipe dream that a million.) kills embryos and 2.) does not look the miracle treatment that human beings was hoping?

Answer 3

All cells in the human body start out, in the embryonic stage, as undifferentiated stem cells. (That's because we originate as a single zygote cell, so obviously all the cells at the earliest stage are identical.) Stem cells then specialize into the various specialized calls that create our organs and all the types of tissue in our bodies.

The focus on therapeutic embryonic stem cell research is to provide a basis for regenerating tissues that are destroyed by sickness or environmental toxins or toxic therapy (like chemotherapy), which cannot normally be regenerated in an adult body.

Answer 4

Stem cells are primal cells that retain the ability to renew themselves through cell division and can differentiate into a wide range of specialized cell types. Research in the stem cell field grew out of findings by Canadian scientists Ernest A. McCulloch and James E. Till in the 1960s. The two categories of stem cells are embryonic stem cells, derived from blastocysts and adult stem cells, derived from umbilical cord blood or bone marrow.[1] In a blastocyst of a developing embryo, stem cells differentiate into all of the specialised embryonic tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing specialized cells. As stem cells can be readily grown and transformed into specialized tissues such as muscles or nerves through cell culture, their use in medical therapies has been proposed.

Medical researchers believe that stem cell research has the potential to change the face of human disease. A number of current treatments already exist, although the majority of them are not commonly used because they tend to be experimental and not very cost-effective. Medical researchers anticipate being able to use technologies derived from stem cell research to treat cancer, parkinson's disease, spinal cord injuries, and muscle damage, amongst a number of other diseases, impairments and conditions. However, there still exists a great deal of social and scientific uncertainty surrounding stem cell research, which could possibly be overcome through public debate and future research.

Stem cells, however, are already used extensively in research, and some scientists do not see cell therapy as the first goal of the research, but see the investigation of stem cells as a goal worthy in itself.

There exists a widespread controversy over stem cell research that emanates from the techniques used in the creation and usage of stem cells. Embryonic stem cell research is particularly controversial because, with the present state of technology, starting a stem cell line requires the destruction of a human embryo and/or therapeutic cloning. Opponents of the research argue that this practice is a slippery slope to reproductive cloning and tantamount to the instrumentalization of a human being. Contrarily, medical researchers in the field argue that it is necessary to pursue embryonic stem cell research because the resultant technologies are expected to have significant medical potential, and that the embryos used for research are only those slated for destruction anyway. The ensuing debate has prompted authorities around the world to seek regulatory frameworks and highlighted the fact that stem cell research represents a social and ethical challenge.

Answer 8

Just type 'stem cell research' into a search engine, i'm sure you will find so much info you'll be an expert!

Answer 9

do a search for it,

or you can go back to class and pay attention, instead of asking stupid questions which you can find out for yourself

Answer 10

i can definetely help you with this. i have a spinal cord injury, which is one of the things it can cure..
i will brb,
