The construction of heart modelling leads path to new therapies (1/10/2008)

Heart disease is still a major killer, especially in the western world, but new therapies based on stem cells and other techniques could now be imminent. Progress is being held back however by the difficulty testing new therapies on human heart tissue, with animal models being only of limited value owing to differences in structure and activity. The only solution in the absence of real human models is to create computerised "in-silico" models that simulate the real heart and enable possible drugs and therapies to be tested without risk to people. Although this is still some way off becoming a reality, substantial progress has been made, and the next steps were plotted at a major workshop held recently by the European Science Foundation (ESF). ...> Full Article

Human derived stem cells can repair rat hearts damaged by heart attack (8/29/2007)

When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal's heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology. The researchers also developed a new process that greatly improves how stem cells are turned into heart muscle cells and then survive after being implanted in the damaged rat heart. The findings suggest that stem-cell-based treatments might one day help people suffering from heart disease, the leading cause of death in most of the world. ...> Full Article

Heart Reboot Causes Blue Screen of Death (2/20/2007)

In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart.
