Repairing a damaged heart may soon be possible using a newly discovered gene combination developed by scientists at Gladstone Institute of Cardiovascular Disease, following their study on stem cells.
The research team led by Dr Benoit Bruneau has found that the combination of three genes can turn nonmuscle cells into beating heart cells.
"With heart disease the leading cause of death in the Western world, this is a significant first step in understanding how we might create new cells to repair a damaged heart," he added.
In the study conducted using mouse model, Bruneau and postdoctoral fellow Jun K. Takeuchi added different combinations of transcription factors to mouse cells, of which these two appeared key in pushing cells into heart cells, however, they were not enough.
Stem Cells From Fat Tissue Offer Hope for MS Treatment
A preliminary study on the use of stem cells obtained from a patient's own adipose tissue in the treatment of multiple sclerosis (MS) has shown promising results.

They are a mix of transcription factors, which bind to DNA and influence gene expression, and a heart-specific chromatin-remodelling protein.
