Researchers at Duke-NUS Medical School, Singapore, have developed an approach to regenerate heart muscle using stem cells. Their method for priming stem cells to become heart tissues could potentially enable heart regeneration stem cell therapies, according to their study published in the journal Cell Reports.
The self-regeneration of human heart muscle following injury is extremely limited. Scientists have been studying techniques to prompt different kinds of stem cells to differentiate into heart cell precursors, which could then help rebuild heart muscle fibres. However, their approaches have not yet met regulations set forth by the US Food and Drug Administration and the European Medicines Agency for regenerative therapies.
Dr. Lynn Yap, a Senior Research Fellow at Duke-NUS’ Cardiovascular and Metabolic Disorders (CVMD) Programme and the study’s first author, explained, “Regulatory authorities specifically require these stem-cell-derived precursors be prepared from human-only cells and in cultures that use clearly defined chemicals and no animal components. The method must be reproducible, and the cells must have clear characteristics while not leading to adverse side effects when injected.”
