If you remove a few cells from an embryo would it effect the development of a fetus or child later on?

Question

i just read part of an article in newsweek online that said scientists might have solved the stem cell dilema by only using 2 or 3 cells leaving the embryo intact. my question is: wouldnt the removal of cells still affect the development if they used the embryo for pregnancy?

Answer 1

No, it won't have any effect at all. This happens quite frequently in nature. It is not uncommon for a subsection of cells to split away from a devloping embryo. One or both sets of cells then proceed to develop normally. The result of such splitting are what we cal identical twins. Obviusly twins devleop just fine depsite a massive loss of cells in the embryo.


In vertebrates all cells are equivalent at that stage of development, they don'thave specific functions. In fact it is that very propery that makes them so useful. Any cell that is removed can be readily replaced by any other cell.

Only much later in devlopment can the removal of a single cell or a small numberof cells have side effects. That occurs because at those later stages cells start to difefrentiate into organ and tissue precursors. As a result if you remove the liver precursors for example the embryo an never develop a liver.

But in these early stages all cells are identical. Cells that will go on to develop into skin are identical in every way to cells that will develop into the heart. If you remove any cells the other cells just divide and replace them.

Answer 2

An embryo and a fetus are very plenty alive. And a human embryo or human fetus is unquestionably a human existence. people who make the argument approximately seeds or vegetation are lacking the element that we are speaking a pair of transforming into human existence. A fetus at a million or 2 months alongside is plenty previous the point of an user-friendly cellular. while the toddler is needed every physique calls it a sprint one. while that's undesirable they call it a fetus. subsequently existence turns into defined by how plenty that's needed by yet another. it relatively is erroneous. the only time i think of abortion could desire to be allowed is that if the mummy will rather die without one, and the toddler is merely too youthful to offer alive and take a inspect to keep. while there are 2 lives in threat, and you will purely keep one, you may desire to keep the single you may keep. in case you probably did no longer keep the mummy in a case like that, the little you may still die together with her besides. So if so you may desire to keep the existence which would be stored and grieve for the single that may not have the capacity to. optionally available abortion is homicide, ordinary and straightforward. the reality that that's legal does not make it suitable. Slavery develop into legal contained in usa for an exceedingly long term, that did no longer make it suitable. every physique is uninformed in the event that they say a fetus is unformed. It starts off to be stated as a fetus while it has all the essential factors that an person of that species has. earlier that element that's an embryo. earlier that a zygote, and earlier that an ovum. The ovum isn't a separate existence, that's an ingredient of the mummy's tissue. The zygote is a separate existence, even with the shown fact that it many times fails to implant and so dies by itself. The embryo and fetus will in many situations proceed to strengthen and strengthen merely super if no on interferes with the approach.

Answer 3

No. There is something called the 16 cell stage during development (after 4 rounds of mitosis and cellular division) during which you can remove 1 of the cells, leaving 15, and the developing embryo compensates for it later in division. It causes no known harm to the fetus. Of course, as with any new research, more data will have to be collected and more tests run to make sure of these findings before they start using this method.

Answer 4

Not necessarily. Up to a point in embryonic development, all of the cells are equivalent, and more cells are available than are actually needed. With things like frog eggs, up to a point in embryonic development, you can cut the egg into 2 or 3 pieces, and each will develop perfectly normally--giving you clones. In humans and other mammals, that's how identical twins are produced--an embryo splits into two and (usually) both halves develop perfectly normally. So it seems quite reasonable that you could take out some cells up to a point, and everything would be fine.

Answer 5

The embryos they use were never ment for development. In fact, if those embryos werent used for stem cell research they would basicall go down the drain. So, they do not produce chicldren from these embryos regardless if they were researched or not. Ok, hope that helps. I guess that doesnt really answer your question tho. I dont know, it probably has never been done before

Answer 6

I think it might becuase cells undergo mitosis or meiosis to divide and form tissues and organs, so if you took some out during development it might cause the embryo to grow differently. But who knows, it might also just grow more and adapt.
