Stem Cell Treatment Stimulates Cartilage Growth

A compound discovered by Novartis researchers prompts regeneration of cartilage in mice — and may pave way for the development of treatments to reverse painful osteoarthritis.

About 27 million Americans with osteoarthritis know with painful clarity that — unlike the cells of the skin, liver and stomach — the cells of the cartilage don’t regenerate. When the cartilage — that supple, slippery tissue covering joints — wears down, bones rub against each other, causing much pain and disability.

Currently, the only treatments for arthritis are anti-inflammatory and surgery and in severe cases, the joints are replaced. There’s still no way to reverse the disease, even as it affects most elderly people — it affects half of all 50-year-olds, 60 percent of 60-year-olds and an increasing proportion of people as they grow older.

Stem Cell for Cystic Fibrosis – Harvard & Boston University Research

Stem cell for cystic fibrosis? Cooperation between Harvard University stem cell researchers at the Massachusetts General Hospital and Boston University School of Medicine scientists — uncharacteristic between typically competing scientific teams — have brought the world closer to the discovery of a drug for cystic fibrosis (CF), a fatal lung disease ranked among the most widespread life-shortening genetic diseases. Their findings can also be used to develop treatments for other major lung diseases.

In the competitive world of science, where being the first to invent or discover something has been the topmost cherished value for centuries, the cooperation between the two teams is unusual but may point the way to the future in science.

Stem Cell for Diabetes – The Children’s Hospital of Philadelphia

Stem cell for diabetes treatment. A new cell line can provide a safe, prolific source of stem cells for researchers to test transplant therapies — as well as study the diseases themselves safely and more accurately than they can in animal models. Beta cells created in the lab can produce some insulin and may potentially be used to replace the beta cells damaged or destroyed in diabetics.

Researchers from The Children’s Hospital of Philadelphia have created a new type of human stem cell that can develop into many kinds of specialized cells — without the danger of turning into cancer.

Stem Cells Can Repair the Heart? Stemedica & Texas Heart Institute Studies

Scientists say it’s irrefutable: stem cells do help repair heart cells damaged by heart attack and disease

After over 10 years of experimental research on the use of stem cells to repair heart cells damaged by heart disease and heart attack, scientists now say there’s enough evidence to say they are effective. And the search is now on to find the best stem cell type for this type of therapy.

Heart disease has been the world’s top killer for many years now. About 17.3 million people across the world died from cardiovascular diseases in 2008 — a large portion of this number from heart disease.

Can Stem Cells Cure HIV?

Can stem cells cure HIV? Yes, that’s possible — if clinical trials planned by a team of scientists from the University of California in Los Angeles (UCLA) push through in the future, and succeed.

If these prove successful, a breakthrough technique they developed — of genetically engineering stem cells into “warrior” cells that fight HIV — could lead to biologic treatments that could be available to patients in about ten years.

A retrovirus of two strains — HIV-1 or HIV-2 — HIV or human immunodeficiency virus — destroys the immune system’s helper T cells. This loss of T cells causes the dreaded disease, acquired immunodeficiency syndrome (AIDS) that leaves a person vulnerable to life-threatening infections.

Heart Attack Recovery With Stem Cells?

U.S. Study: Stem cells can regenerate heart tissue after heart attack. When someone has a heart attack, great slabs of muscle tissue die and many vessels are destroyed. Up to 40 percent of heart tissues die, and dead muscle is replaced by scar, not newly formed muscle.

The heart is a muscle that pumps blood to the body’s organs, and when scar tissue forms, it can’t contract properly. This predisposes heart attack survivors to arrhythmias, enlargement of the heart, heart failure and death.
