Describe in one paraghraph what embryonic and adult stem cells are and how knowing the difference relates to the artice (the article was on stem cells from human skin; no embryos needed). How do i answer that and what are embryonic cella and adult stem cells

Since this is not my area of expertise, I searched Google under the key words "'stem cells' adult embryonic" to get these possible sources:

http://stemcells.nih.gov/info/basics/basics5.asp
http://en.wikipedia.org/wiki/Stem_cell
(Broken Link Removed)

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.

To answer this question, let's start by understanding what embryonic and adult stem cells are. Embryonic stem cells are derived from embryos at the blastocyst stage, which is usually around five to six days after fertilization. They have the ability to differentiate into any cell type in the body, making them highly versatile for potential therapeutic applications. On the other hand, adult stem cells are found in various tissues and organs in the body, where they play a role in tissue maintenance and repair. They are more limited in their differentiation potential compared to embryonic stem cells, typically giving rise to cell types specific to their tissue of origin.

In regard to the article about stem cells derived from human skin, the mention of no embryos being needed indicates that these researchers have found a way to reprogram adult cells, such as skin cells, into a pluripotent state similar to embryonic stem cells. This process is often referred to as induced pluripotent stem cell (iPSC) technology. By understanding the difference between embryonic and adult stem cells, it becomes clear that the researchers in this article are utilizing adult stem cells (in this case, skin cells) that have been transformed into pluripotent stem cells, which eliminates the ethical concerns associated with using embryonic stem cells.
