Washington, August 20 : UC Riverside researchers have devised a way to grow human embryonic stem cells in the lab without using animal derived materials, bringing the use of embryonic stem cells for medical purposes closer to reality.
Noboru Sato, an assistant professor of biochemistry, that the new method may revolutionise cell therapy to treat diseases like Parkinson's and diabetes mellitus.
This advancement attains significance because the majority of researchers presently culture the cells using animal-based materials that can transmit viruses other pathogens to the stem cells, making them unsuitable for medical use.
Sato insists that his method is cleaner and easier to use than conventional methods of culturing human embryonic stem cells.
He says that his method does not result in stem cells with compromised pluripotency - the potential to differentiate into any of the specialized cells of the body such as neurons, cardiac muscles, and insulin-producing cells.
"Until now, it was generally assumed that the hESC colony formation was pivotal for maintaining pluripotency. But we show that pluripotency can be retained independent of close cell-cell contact," Sato said.
Prue Talbot, the director of UCR's Stem Cell Center of which Sato is a member, noted that Sato's discovery could affect the way embryonic stem cells are grown in the future.
"His work is certainly an important step forward in both understanding signal transduction pathways in stem cells and in the development of an improved methodology for culturing stem cells," she said.
A research article descriing the Sato's discovery has been published in the online edition of the Public Library of Science (PLoS) ONE.
Thanks for posting. I just got off the phone with my sister (she’s with my mom...Parkinson) in Arizona and mom is not doing well.
just hype to rationalize using a cell line for which they sacrificed a life.
aborted fetuses - just doing a job that live dems won’t do.

These people have to boast (in headlines, of course) that their latest method of destroying human life is really, really, really about curing dreadful diseases . . . even though they have yet to find any use for embryonic cells other than the purpose for which God allows them to be created in the first place.
they are now doing this with a persons own nasal cells which they convert to stem cells.
I’ve read where they been successful - and they didn’t have to kill any fetuses to get there.

Scientists Make Red Blood Cells From Human Embryonic Stem Cells
Biological properties and enucleation of red blood cells from human embryonic stem cells
Hmmmm...so they brag about not using animals but are indifferent about killing babies? And all for something which has produced no results?!
Looks to me like their cause is to kill babies.
My mother’s Parkinson’s gets worse everyday. I took her to the Urologist on Monday, and she had to be catheterized. She’s in the wheelchair, and her one eye keeps closing. God bless her. She has never complained once...
Exactly. Thanks for the reminder. BUMP!
“signal transduction pathways”...it’s just a blob of tissue.
That's the thing about research - treatments with great potential often do not pan out, while other treatments take forever and then explode on the scene.

You supply the computer(s) and a little bit of electricity, Stanford supplies a simple program that runs in the background, and we all benefit from the research into Alzheimer's. Parkinson's and many other wasting diseases.
We would love to have you join our little band and make a difference.

Cannibalism is not an appropriate treatment for ANY malady. These ghouls keep pushing embryonic stem cell therapy without a SINGLE positive result after years of trying. It’s not research, it’s a ripoff.
Not that I'm defending this boondogglish endeavor, but most probably they are not bragging about it for the PETA reasons. Typically embryonic stem cells are grown in a culture of mouse cells, which contaminate the culture and make them unsuitable (in yet another way) for use in humans.

*********************************************************
Nobody will disagree with your first statement ,, and I also agree that ESC research hasn’t yet produced any worthwhile results and can be called a “ripoff” if you like ,, however as researchers are now able to harvest various adult stemcells and convert them to a pluripotent state , mimicing ESC’s I no longer have any objection to ESC research as long as the cells aren’t derived from abortions.
Understand. You are correct.
I purposefully narrowed the focus to contrast the lack of basic morals. The scientists are talking method while I am shouting murder.
To me, this is of the same "medical" nature as Hitler's "experiments".
Unless these modified “adult” cells are used for cloning - a different kind of morally outrageous behavior - they are fully appropriate subjects for research and therapies. But they are actually NOT “embryonic stem cells” and should not be referred to as such. More properly, they are somatic-cell derived pluripotent cells.
So I intend to remain as firmly opposed to “ESC research” as I have been from the first time I learned about what it is, while at the same time applauding and encouraging the research and development of therapies and treatments involving living human cells from NON-embryonic sources.
