Genetically modified or engineered stem cells can be successfully integrated into damaged organs to differentiate, promote healing, and restore tissue function.
The claim states that replacing DNA in stem cells (gene editing/genetic selection) and placing them in damaged organs heals the tissue. Several papers, particularly [7] and [11], discuss genetic manipulation and gene editing combined with stem cell transplantation to repair and regenerate damaged tissue such as heart muscle. Therefore, the evidence supports the claim.
