London: Foetal stem cells help mothers to recuperate from heart damage, a new study by Indian origin scientist has suggested.The research, conducted by Hina Chaudhry of the Mount Sinai School of Medicine in New York City and team, took into consideration two kinds of mice: normal mice and genetically engineered mice, to generate green-fluorescing protein in all their body cells.After mating the normal female mice with GFP-producing male mice, half the resulting foetuses produced the protein too, making it easier to identify any foetal tissue in mother. The researchers then gave heart attacks to pregnant mice and killed them after two weeks to examine their heart.The study revealed that there were some fluorescent cells in the mothers’ damaged heart tissue, where they had accelerated repair by changing into new heart cells, including beating cardiomyocytes and blood vessel cells, New Scientist reported.According to Chaudhry, the phenomenon is an evolutionary mechanism, which involves the foetus promoting its own survival by protecting its mother’s heart.
