Deep inside his blackberry-shaped
blastocyst, some of his cells clumped together to form an "inner
cell mass" that would later become Jacob's body, umbilical
cord, and amniotic sac. The boy had been born at 34 weeks' gestational age (weight
2,300 g), and he was treated for a few days with antimicrobial drugs
after prolonged rupture of amniotic sac membranes, even though
early-onset infection had not been confirmed. With another set of experiments, they uncovered evidence that SPA
triggers birth by activating fetal immune cells called macrophages,
which then leave the amniotic sac and travel to the uterus. |
