In what can only be described as a miracle worker, it is possible that a pregnant mother can be saved by her baby from the womb. In reports where a mother’s organs were critically damaged, doctors have seen fetus send stem cells to repair them. It shows how amazing the human body is, the miracle of life really does exist.
It has long been a running internet joke, a science meme, that explains how a pregnant mother’s fetus can send its stem cells to its mother for organ repairs. The joke revolves around imagery that explains: we must save the mothership! And though most internet memes do simply spread urban myths, this one is actually for the most part entirely accurate. The science behind the claim is actually pretty solid and well researched.
Of course, the joke is still problematic, the baby does not send anything, this happens during the time that the baby is not really even there yet: it happens during the fetus stages of pregnancy. And there is no conscious decision where the baby decides to send out their stem cells, this is a kind of biologic automatic response.
What happens is that during a mother’s pregnancy there is a certain amount of fetal cells that are transferred over to the mother, it is a process known as fetal cell microchimerism. And these cells can even migrate through the circulation, reaching tissues and bone marrow. The reason they can repair any damage to the mother’s organs is that they are not rejected, and also tend to stay present in a mother’s body for decades after the pregnancy.
Stem cells are essentially a blank canvas, they can turn into different tissues and play a very important part in the development of a fetus. The amazing part is that they can be transported into the mother’s system and become fully integrated despite different genetics. A 1996 study by the National Academy of Sciences, found that these stem cells can exist in a mother’s body as long as 27 years after birth and that these cells become present in multiple organs.
Though it has not been proven that the stem cells repair damaged organs in human mothers, a study in 2015 proved that it did happen in mice. And there are many tales of mother’s with cancer, going into remission and being cured after pregnancy – even when stopping chemo for the safety of the pregnancy.
