Promoting Tissue Growth/ Repairing Damaged Tissue
Researchers at the Icahn School of Medicine at Mount Sinai in New York administered VN-100 (a gene therapy vector) carrying cyclin A2( gene that's makes heart cells divide) to a group of pigs who have had heart attacks. A pig heart highly resembles a human heart. Since this gene is normally is no longer used in mammals after birth, heart muscle cells are not able to divide and repair themselves after suffering from a heart attack. The results were promising, because they showed signs that the gene helped form new heart muscle and also improved the pumping function of their hearts. This has the potential to heal cardiac damage in humans.
