Response: difference between adult stem cells and hESCs 13

This article was the perfect background information I had been looking for. There were basic pros and cons of hESCs and adult stem cells, as well as clearly stated differences. I am aware that these pros, cons, and differences might be altered since the article was written months ago. However, it was an excellent base to help me see the distinct differences between hESCs and adult stem cells.

I found it interesting that scientists were expecting that hESCs were more likely to be rejected during transplant than adult stem cells. This does make sense though, adult stem cells come from one's own body, where as hESCs are foreign.

Also, I had never read anywhere else that adult stem cells are rare. I was under the assumption that they were everywhere! As it turns out, they are more difficult to find and harder to culture than hESCs. I also didn't know that adult stem cells can only be cultured into more of the original tissue that they were taken from. Where as hESCs can be cultured into any type of cell.

I'm pleased to have found this information, but still wary, it might not all be completely accurate. For example, they said hESCs were more likely to be rejected from the body, but hESCs also don't produce tumors like adult stem cells do.

Notes: difference between adult stem cells and hESCs 13

hESCs can be easily cultured, adult stem cells are rare and more limited

hESCs are pluripotent and can become any type of cell, adult stem cells can only be cultured into more of their original tissues

hESCs are easy to culture, adult stem cells are challenging to find in mature tissues

number of cells you can culture through adult stem cells are still limited. This is a challenge because mass amounts of cells are needed for stem cell therapies.

scientists are curious to see if hESCs will be rejected less during transplant than adult stem cells. they will be able to know after clinical trails are more developed since they have only recently been approved the the United State's FDA.
