Alzheimer’s Stem Cell Research: Ask the Expert – Larry Goldstein, UCSD

In this first installment of CIRM TV’s “Ask the Expert” video series, Larry Goldstein of the University of California, San Diego answers questions about finding stem cell based therapies for Alzheimer’s disease. Readers of CIRM’s Facebook, Twitter, and research blog sent in the questions over the past few weeks. Dr. Goldstein is a CIRM grantee and director of the UC San Diego stem cell program.

Looking Below the Surface: Stem Cell Behavior in Real Time

Scientists have for the first time watched and manipulated stem cells as they regenerate tissue in an uninjured mammal, Yale researchers report July 1, 2012, online in the journal Nature.

Using a sophisticated imaging technique, the researchers also demonstrated that mice lacking a certain type of cell do not regrow hair. The same technique could shed light on how stem cells interact with other cells and trigger repairs in a variety of other organs, including lung and heart tissue. Valentina Greco, assistant professor of genetics and of dermatology at Yale School of Medicine, and her team focused on stem cell behavior in the hair follicle of the mouse. The accessibility of the hair follicle allowed real-time and non-invasive imaging through a technology called 2-photon intravital microscopy. Using this method, Panteleimon Rompolas, a post-doctoral fellow in Greco’s lab and lead author of this paper, was able to study the interaction between stem cells and their progeny, which produce all the different types of cells in the tissue. The interaction of these cells with the immediate environment determines how cells divide, where they migrate and which specialized cells they become. The technology allowed the team to discover that hair growth in mice cannot take place in the absence of connective tissue called mesenchyme, which appears early in embryonic development.

The study was funded by an Alexander Brown Coxe postdoctoral fellowship. This work was supported in part by the American Skin Association and the American Cancer Society and the Yale Rheumatologic Disease Research Core Center and the National Institutes of Health.

Other Yale authors include Elizabeth Deschene, Giovanni Zito, David G. Gonzalez, Ichiko Saotome and Ann M. Haberman.

Researchers discover drug that destroys human cancer stem cells

A team of scientists at McMaster University has discovered a drug, thioridazine, successfully kills cancer stem cells in the human while avoiding the toxic side-effects of conventional cancer treatments. Mick Bhatia is interviewed in this video regarding the discovery.

Stem Cells from Bone Marrow Grows New Bone

A research team led by UC Davis Health System scientists has developed a novel technique to enhance bone growth by using a molecule which, when injected into the bloodstream, directs the body’s stem cells to travel to the surface of bones. Once these cells are guided to the bone surface by this molecule, the stem cells differentiate into bone-forming cells and synthesize proteins to enhance bone growth. The study, which was published online today in Nature Medicine, used a mouse model of osteoporosis to demonstrate a unique treatment approach that increases bone density and prevents bone loss associated with aging and estrogen deficiency.

Stem Cells Reverse Heart Damage


By AlysaCartee, Anchor Megan Murphy

A breakthrough discovery in stem cell treatments. A patient’s own stem cells could actually regenerate the heart after a heart attack. WFLD explains the findings.

“The studies found that recent heart attack victims who receive stem cell infusions had a drop in unhealthy heart scar tissue from 24 to 12 percent.”

The procedure is minimally invasive. A catheter is inserted through the patient’s vein and a piece of heart muscle about the size of a peppercorn is removed.

That biopsied tissue is then grown in a petri dish and reintroduced to the damaged portion of the heart. This new procedure could change the way heart attacks are treated. ABC reports the typical damage a heart attack leaves and the limited options for treatment.

“The damaged scar tissue that results from a heart attack diminishes heart function, which can ultimately lead to enlargement of the heart. At best … there are measures doctors can try to reduce or compensate for the damage, but in many cases, heart failure ultimately sets in, often requiring mechanical support or a transplant.”

But the new treatment challenges the conventional wisdom that once the heart is damaged, it can’t be repaired. Doctor Sanjay Gupta told CNN this breakthrough in the use of stem cells means a few different things for the medical community.

“We’ve been talking about the promise of stem cells for so long but people have really yet to see it in action. … It really proved two things. First of all that this could be done safely. That’s always the first question. And second that it provided some benefit.”

As Fox News reports, the study is positive — but there are a few mysteries that need to be solved.

“…while the patients grew new heart muscle and saw a dramatic reduction in scar tissue, the actual function of their hearts did not show a significant improvement. And it appeared the stem cells themselves may not have turned into cardiac muscle, but rather they stimulated the heart to produce new muscle cells.”

Researchers will follow the patients who received the treatment to document long term effects, and a follow up study is planned for later this year.
