MIAMI, Fla. (Ivanhoe Newswire) — Some are calling it the next big frontier in cardiac treatment — injecting stem cells to regenerate the heart. But the experimental procedure means major surgery. Doctors are opening the door for heart patients who want to test the benefits of stem cells — without an operation.

One heart attack behind him, Max Eaton is now struggling with heart failure. He’s hoping stem cells are the answer to heal his ailing heart. “I happened to run into this article, which was the second or third time I heard about this stem cell research, and decided nothing ventured, nothing gained,” Eaton told Ivanhoe.

Instead of surgery, where the chest is opened and stem cells are injected into the heart, Alan W. Helman, M.D., an interventional cardiologist at the University of Miami, delivers the cells through a catheter that’s threaded through the groin. The spiral-shaped needle at the tip is screwed into the heart.

“We can now inject the cells exactly where we want to in the inside part of the heart, and we can do it in multiple different locations,” Joshua Hare, M.D., a cardiologist at the University of Miami, told Ivanhoe.
Doctors say it’s a more efficient way of delivering stem cells (…) Now, Eaton is hoping his wager on stem cells will pay off.

Doctors say Eaton is responding well to his stem cell treatment. All of the stem cells being used in this trial are adult stem cells. Studies have shown injecting heart attack patients with adult stem cells can increase the pumping power of the heart. However, it is not an approved treatment for re-growing heart tissue.

RIYADH – Stem Cells Unit at the Department of Anatomy in King Saud University will organize a conference on stem cell research and medical reconstruction at the Faculty of Medicine and King Khalid University Hospital on Nov. 7-9. First of its kind in the Kingdom, the conference will be held in cooperation with the KSU’s Center for Medical Education, the Australian National University and the University of South Denmark.
President of the Organizing Committee of the Conference, Dr. Abdullah Al-Dahmash, said here Saturday that the conference aims at presenting the latest developments in the field of stem cell research and therapeutic applications; to accentuate new technologies, research and applications of stem cells.

The aim is also to highlight the major advances in stem cell researches in the Kingdom in general, and King Saud University in particular and to increase awareness of the importance of stem cell researches.
The conference will address many topics including the role of stem cells in treating some diseases, especially those suffered by the Saudi society as well as modern techniques in stem cell researches (…)

International Stem Cell Corporation, announces that it has launched fifteen new human cell culture products into the commercial research markets over the last twelve months through its wholly-owned subsidiary, Lifeline Cell Technology, (Walkersville, MD), leading to a 12-month average month-to-month revenue growth of 50%. ISCO, the parent company, is the first company to create human “parthenogenetic” stem cells from unfertilized eggs. Parthenogenetic stem cells not only solve ethical problems, but also promise to minimize immune-rejection by providing cells that can be immune-matched to large segments of the population.

These products represent milestone achievements in ISCO’s strategy of generating revenue from the sale of research products, while building infrastructure from that effort to expand the manufacturing and quality control capacities ISCO needs to commercialize the therapeutic applications of human parthenogenetic stem cells.

One of its newest and most promising products consist of “xeno-free” human cells and culture reagents that allow researchers to study embryonic stem cells without contamination from animal (non-human) components. These products meet the needs for stem cell research to be done using “human-only” systems. Other products include Lifeline’s living human cells and reagents for research and drug development into cardiovascular, kidney, lung, nerve, eye and skin disease. Lifeline is continuing to develop unique reagents and media for the growing field of stem cell research. The “Lifeline” brand of products consist of human cells and the culture reagents and growth factors needed to grow the cells.

According to Jeffrey Janus, CEO of Lifeline, “We are proud of the quality of our new products, as reflected in the sales growth they are exhibiting in the human cell research markets. We look forward to launching more new products into the growing markets for stem cell research and drug development. These products will contribute to the success of ISCO, not only by supporting ISCO’s therapeutic research, but also through the development of critical manufacturing and quality control systems necessary for ISCO to produce therapeutic human cells in the future.”

Lifeline’s products can be found at www.lifelinecelltech.com

SANUWAVE Inc., an emerging medical technology company focused on the development and commercialization of non-invasive, biological response activating devices in the regenerative medicine area, reported that scientific findings titled “Extracorporeal Shock Wave Stimulation of Osteoprogenitor Cells” were presented at the 2009 International Bone-Tissue-Engineering Congress (“Bone-Tec”) in Hannover, Germany, which was held October 9-11, 2009.

Dr. Myron Spector, PhD, Professor of Orthopaedic Surgery (Biomaterials) at Harvard Medical School, Director of Orthopaedic Research at Brigham and Women’s Hospital and Director of Tissue Engineering at VA Boston Healthcare System, was an invited guest speaker at the Conference. The Bone–Tec Congress featured an international scientific forum to discuss progresses in modern bone tissue regeneration and extended a worldwide network to exchange findings on the latest developments.

Dr. Spector’s team employed SANUWAVE’s Pulsed Acoustic Cellular Expression (PACE™) technology in preclinical research to create autogenous sources of stem cells for bone tissue engineering. Results support the proposition that PACE™ could be employed as a non-invasive technique to cause proliferation and thickening of the cambium layer of the femur’s periosteum for the subsequent intraoperative harvesting of progenitor stem cells days later for bone or cartilage regeneration.

PACE™ stimulated a dramatic proliferation and thickening (up to 10 fold) of osteoprogenitor stem cells, precursors to bone and cartilage cells, in the cambium layer of the periosteum in the femur of the adult rats within 4 days. Neovascularization and new bone formation within the thickened periosteum were also evident after 4 days.

Dr. Spector said, “This research has shown great potential. Through more study, this technology could further advance tissue engineering autologous transplant techniques towards clinical applications such as bone reconstruction and cartilage defect repair.” (…)

Like Samson, researchers in the field of stem cells have used the jawbone to make a point. Dr. Gordana Vunjak-Novakovic and her team at Columbia University have manipulated adult stem cells to grow one of the most difficult sections of bone to replace, the temporomandibular joint. This jawbone was created by allowing pluripotent cells harvested from marrow to grow in a scaffold that was fashioned to mimic the TMJ’s shape.

It is the first accurate and anatomically sized bone created by stem cells in a lab. Dr. Vunjak-Novakovic hopes that this new creation will serve as a proof of concept — if they can make the complex TMJ, they should be able to grow many other bones in your body. While this work is truly amazing, it still has some major hurdles to jump before it could be used to replace damaged or cancerous bones in humans (…)

Growing a fully functional part of the human body depends not only on coaxing adult stem cells to replicate and specialize, it also requires one heck of a nursery. The Columbia team has developed a bioreactor which provides all of the necessary nutrients for stem cells to develop into bone. The shape of the scaffold inside the bioreactor was defined through the use of many digital pictures. Which raises the possibility that eventual bone recipients could have the new body part made to look exactly like the old one. While the bioreactor is top notch, work still has to be done to find a way for the newly created bone to carry its own blood supply that can be easily adapted into the host (…)

Scientists have taken the first steps toward producing the “heart patch,” a design for a medical implement used to repair damage from heart disease, a new study suggests.

Last week, researchers from Duke University presented the results of a study which, using mouse embryonic stem cells, examined the way these cells develop into heart muscle, HealthDay News reports (…)
