Resumen de Stop multiple miscarriages
Miscarriage could be caused by too many ageing cells in the womb and a fluctuating immune response. This suggests carefully timing a pregnancy could prevent miscarriage and increase the chance of carrying a baby to term. Jan Brosens at the University of Warwick, UK, thinks the balance between stem cells, ageing cells, and immune cells could be to blame. When his team took samples from the uteruses of women who hadn't had miscarriages, they found that the number of natural killer cells cycled in a predictable manner throughout the month. But in women who had miscarried several times, the numbers of natural killer cells rose for several months in a row, before they disappeared, and then began to accumulate again.
