Las células madre del cordón umbilical salvan vidas!
🤰🏼In a groundbreaking study from Mount Sinai School of Medicine, scientists found that stem cells originating from the fetus—and carried via the placenta—can travel to an injured area in the mother's heart and aid in its repair.
Researchers observed these fetal cells migrating to the damaged cardiac tissue, where they transformed into vital heart components, including smooth muscle cells, blood vessel cells, and cardiomyocytes.
Even more remarkable, when grown in lab cultures, these cells began beating on their own, demonstrating real cardiac functionality. The findings, unveiled at the American Heart Association’s Scientific Sessions and published in Circulation Research, suggest a natural regenerative mechanism activated during pregnancy.
What makes these placenta-derived stem cells especially promising is their ability to integrate into maternal tissues without causing immune rejection—an issue that often complicates stem cell therapies. Because the placenta is usually discarded after birth, these cells offer an ethically acceptable and highly targeted option for regenerative medicine.
