stem cell research — regenerative medicine A scientist conducting research on stem cells.

In the field of regenerative medicine, researchers have explored the use of cardiac stem cells to repair damaged tissue. Specifically, cardiac stem cells derived from patients with heart failure were engineered to express the protein Pim-1, which is known to promote cell survival and proliferation.1

When these Pim-1-engineered cells were injected into mice that had suffered a myocardial infarction, the cells were found to enhance the repair of the injured heart muscle tissue. This approach highlights the potential of genetic modification to improve the therapeutic efficacy of stem cells in treating cardiovascular damage.1
