--In fact, it seems to me he's SPECIFICALLY saying that earlier efforts using ES cells were problematic and that that's why they're NOT doing that, this time 'round.
Feedback?
--What exactly do you think is misleading? Be more specific.---
The above title has the word "ADULT" when in fact the cells were not taken from an adult nor are they adult stem cells. Seems the poster wants to imply something that is not true.
the term "adult" indicates the cells were not taken from embryos. the term "adult" is also used to indicate cells from umbilical cord blood, placenta and amniotic fluid. From under what rock did you just craw out? I did not say these were stem cells. Many freepers have requested from me that I use the term Adult in titles when referring to non-embryoic cells. I have yet to see you post any threads of value on the free republic, just comments that have no substance. You are being very silly and pathetic and have not contributed to this cause.
I see you did not challenge the accuracy of my post.
--Did you perhaps think that "fetal stem cells" were different from "adult stem cells"?--
I do not know what you are referring to.
The researchers said they wanted to pick them up a little bit earlier in the life cycle and then work them through to what amounts to an adult status ~ just as it happens.
They are attempting to avoid working with celltypes (embryonic stem cells) that cause cancer.
Because he just signed up 6 days ago.
--The stem cells --
They weren't stem cells.
You can call them what you want, but there they were ~ doing what stem cells do.

No. Stem cells are undifferentiated.
Embryonic "stem cells" are undifferentiated, and to a degree they can do anything they wish, and no one seems to be able to do anything about it.
You go injecting embryonic stem cells into the brains of the handicapped they are going to develop into cancer.
You know that.
--Stem cells are NOT undifferentiated ~ --
Perhaps you should check your references ...
--Those cells really can't be differentiated from "adult stem cells". --
They can easily be differientiated from "adult stem cells" as these were differentiated and adult stem cells are NOT differentiated.
There's a continuum of development in stemcells, and various terms have been invented to more or less indicate the level of development.
Might be better to use those terms than to mess around with "differentiate" ~ particularly since that term has a quite ordinary meaning related to how I or you might see different things.
I am using NIH definitions.
--Just being consistent with the definitions posted at Wikipedia, I think you are trying to use "differentiate" in place of several other terms.--
Wikipedia:
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.
...
Adult stem cells are undifferentiated cells found throughout the body that divide to replenish dying cells and regenerate damaged tissues.
She's already two faced...
They are not.
