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

Mechanism by which Signaling Pathways Regulate Growth and Differentiation of Adult Muscle Stem Cells is Revealed (1/8/2008)

During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue. Although the signaling pathways controlling muscle regeneration are fairly well known, how these signals lead to altered chromatin structure remains undiscovered. A group of scientists at the Burnham Institute for Medical Research in La Jolla, CA, analyzed the mechanism by which certain cellular signaling cues cause epigenetic modifications when released within the regenerative microenvironment, thus controlling the expression of genes that regulate growth and differentiation of muscle stem cells that repair injured muscle. ...> Full Article

Scientists restore walking after spinal cord injury (1/7/2008)

Spinal cord damage blocks the routes that the brain uses to send messages to the nerve cells that control walking. Until now, doctors believed that the only way for injured patients to walk again was to re-grow the long nerve highways that link the brain and base of the spinal cord. For the first time, a UCLA study shows that the central nervous system can reorganize itself and follow new pathways to restore the cellular communication required for movement. ...> Full Article

Human Embryonic Stem Cell Lines Created That Avoid Immune Rejection (12/24/2007)

In a groundbreaking experiment scientists from International Stem Cell (ISC) Corp. derived four unique embryonic stem cell lines that open the door for the creation of therapeutic cells that will not provoke an immune reaction in large segments of the population. The stem cell lines are "HLA-homozygous," meaning that they have a simple genetic profile in the critical areas of the DNA that code for immune rejection. The lines could serve to create a stem cell bank as a renewable source of transplantable cells for use in cell therapy to replace damaged tissues or to treat genetic and degenerative diseases. ...> Full Article
