Animal Studies Show Stem Cells Might Make Biological Pacemaker

In experiments in the lab and with guinea pigs, researchers have found the first evidence that genetically engineered heart cells derived from human embryonic stem cells might one day be a promising biological alternative to the electronic pacemakers used by hundreds of thousands of people worldwide.

How Human Blood Stem Cells Transform Themselves to Repair Injured Animal Hearts

Regeneration of damaged hearts using blood stem cells now appears to be clinically promising, say researchers who show that in mice, human stem cells use different methods to morph into two kinds of cells needed to restore heart function.

Follow the Embryonic Stem Cell Road to Cardiac Cell Progenitors

Johns Hopkins researcher John Gearhart has taken another small step on the road toward replenishing damaged cardiac tissue with pre-cursor cardiac cells grown from human embryonic stem cells (ES cells) in a highly reproducible system through controlled ES cell differentiation.

Harvard Health Letter Picks 2004's Top 10 Health Stories

As it does every December, the Harvard Health Letter has chosen the top 10 health stories of the year. This year's winners include 1-new cholesterol guidelines, 2-cloning for stem cells, 3-Vioxx, and more.

Stem Cell Transplants from Disposable Umbilical Cord Blood Provide Hope

A new study confirms that stem cells derived from the umbilical cords of newborn babies are a viable and effective transplant source for thousands of leukemia patients who have no other treatment option.

Stem Cells' Repair Skills Might be Link to Cancer

Johns Hopkins researchers say there is growing evidence that stem cells gone awry in their efforts to repair tissue damage could help explain why long-term irritation, such as from alcohol or heartburn, can create a breeding ground for certain cancers.

Stem Cell Therapy Effectively Treats Heart Attacks in Animals

Results from an animal study conducted at Johns Hopkins show that stem cell therapy can be used effectively to treat heart attacks, or myocardial infarcts, in pigs. Stem cells taken from another pig's bone marrow, when injected into the animal's damaged heart, were able to restore the heart's function to its original condition.

Method Developed to Replicate Stem Cells from the Heart

In human and animal studies, scientists at Johns Hopkins have developed a fast and safe method for collecting heart stem cells from remarkably small amounts of biopsied heart tissue (15 mg or less), and growing the cells in the lab to get more.
