Cloning stem cells: What does it mean?

Posted: May 18, 2013 at 1:48 pm

STORY HIGHLIGHTS

(CNN) -- A human embryo, containing about a couple hundred cells, is smaller than the period at the end of a sentence. Scientists need strong microscopes to see these precursors to life, and to take from them stem cells, which have the potential to become any cell in the body.

Earlier this week a breakthrough in this field was announced. A group of researchers published in the journal Cell proof that they had created embryonic stem cells through cloning. The scientists produced embryos using human skin cells, and then used the embryos to produce stem cell lines.

"It is an incredibly powerful approach with potential to generate almost any tissue in the body, genetically identical to the patient," said Jeff Karp, associate professor at Harvard Medical School and co-director of the Center for Regenerative Therapeutics at the Brigham and Women's Hospital in Boston.

Creating an embryo just from an egg and a skin cell seems like magic, but just how practical would the subsequent stem cells be? And does it actually amount to cloning?

What they did

Normally, an embryo is created when sperm enters the egg and it starts to divide. But, in the Cell study, Shoukhrat Mitalipov and colleagues at Oregon Health and Sciences University began with skin cells from an 8-month-old baby that had a genetic disease. They did not use sperm.

To create each embryo, they took the DNA out of an egg, so that it was hollow, and replaced it with the skin cell's DNA instead. The baby's DNA was the only genetic material being used.

With the help of chemicals, the egg started to divide just like a normal fertilized egg would. Then, within several days, embryos genetically identical to the baby were created, from which stem cells were derived.

Embryonic stems research is inherently controversial because in order to use the stem cells for science, the embryo, which is a collection of cells that could develop into a fully formed human, is destroyed, even though embryos in these procedures are left over from in vitro fertilization.

Cytomedix to Present at the World Stem Cells & Regenerative Medicine Congress 2013

Posted: May 18, 2013 at 3:48 am

GAITHERSBURG, MD--(Marketwired - May 17, 2013) - Cytomedix, Inc. (OTCQX: CMXI), a regenerative therapies company commercializing and developing innovative platelet and adult stem cell technologies, announced today that Edward Field, the Company's Chief Operating Officer, has been invited to make a presentation on Partnering & Collaboration at the World Stem Cells & Regenerative Medicine Congress 2013, which will be held May 21-23, 2013 in London, United Kingdom.

Presentation Details

Time: Tuesday, May 21, 2013 @ 11:55am BST (6:55 am EST)

Track Title: Commercialisation through Collaboration: What Does Partnering In This Industry Actually Look Like?

Location: Victoria Park Plaza Hotel, London, UK

During the presentation, Mr. Field will highlight Cytomedix's two collaborations that are advancing clinical stage therapies.The first is a collaboration with the National Institute of Health (NIH) and the Cardiovascular Cell Therapy Research Network (CCTRN) for conduct of the PACE study, an 80 patient, double-blind, placebo-controlled clinical trial designed to look at the safety and efficacy of ALD-301 in peripheral artery disease patients diagnosed with intermittent claudication.This is the first ever randomized clinical trial to look at the benefits of autologous stem cell therapy in this indication.The second collaboration is with Duke University Medical Center, which is conducting a Phase 1 clinical study with ALD-451 in patients that have been treated for glioblastomas, which is the most aggressive form of brain cancer.This open-label study is designed to enroll up to 12 patients and is intended to demonstrate the safety and feasibility of ALD-451 when administered intravenously in patients with grade IV malignant glioma following surgery, radiation therapy and treatment with temozolomide.

About the World Stem Cells Regenerative Medicine Congress 2013The World Stem Cells & Regenerative Medicine Congress 2013 is Europe's largest and most senior conference for the stem cell research and regenerative medicine community.It is now in its 8th year. Topics covered will include streamlining clinical development, commercialising a stem cell-based therapy and exploiting alternative sources of funding. For more information please visit: http://www.terrapinn.com/2013/stemcells/index.stm.

Replicating Oregon Cloning in California: Views on the Legality

Posted: May 17, 2013 at 12:01 pm

Oregon's stem cell cloning achievement
has triggered some discussion about whether it could be replicated
legally in California, which bans paying for eggs as was done in
Oregon.

Stanford researcher Irv Weissman said
it is “not true” that Oregon's stem cell research would be
illegal in California. Leftovers from IVF clinics could be used, he said.
But in response Oregon researcher
Shoukhrat Mitalipov said that “SCNT (the process he used) did not
work with discarded human eggs.”
He added,

 “SCNT worked with eggs from
healthy young volunteers (paid of course). IVF patients (whether paid
or not) have reproductive health problems and may not provide
acceptable quality eggs for SCNT.” 

Weissman said,

 "Not true. They did
it with nearly 40 percent efficiency, which does not require paying
for eggs, just use leftovers from IVF clinics."

There is no question that it is illegal
to pay donors for their eggs in California. The question is whether
the research could be done properly without using paid donors. In recent
years, researchers at Harvard and elsewhere have said they needed paid donors for stem cell research to properly perform their research
and could not find them without providing compensation.

Weissman Says Oregon-style Stem Cell Research Could be Done in California

We have queried Shoukhrat Mitalipov in
Oregon concerning his views on Weissman's comments. We welcome other
comments as well. Comments can be filed directly by clicking on the word "comment" at the end of this item or you can email them to djensen@californiastemcellreport.com
We should also note the comment from
researcher Paul Knoepfler of UC Davis who notes that SCNT cloning is
permissible in California, which is what was done in Oregon. The
state does ban reproductive cloning, however.
