Recent research has revealed that cardiomyocyte–heart muscle cells–integrations into the human body can be achieved through the implantation of engineered heart muscles into the heart’s surface while a patient is undergoing immune system suppression.
This research builds on earlier studies of cardiomyocyte implantation and the promising results from large animal models. However, these earlier models showed many limitations, especially evident in tissue-engineered allografts and xenografts, where the immune response from these animals often rejected long-term engraftment.
Researchers recently turned to the rhesus macaques from their studies, driven by the genetic similarity between humans and this species.
Through a detailed process, the research team was able to transform stem cells from the rhesus macaques into heart cells. These heart cells were then combined with other materials to create a small piece of genetically engineered heart muscle that acts like real heart tissue, able to exhibit the distinctive features of cardiac muscle through movements such as contractions.
The team’s work holds potential to revolutionize heart surgeries, offering hope to millions of patients and families worldwide.
