Cells at Work! Lady, Volume 3

Pregnancy can be tough on a lady’s body…and the cells inside her, too! When half of the baby’s DNA looks like a foreign invader, what’s an immune cell to do? As the soon-to-be mother prepares for labor, her cells are on double duty working hard to protect her little princess as well. Together, mother and her cells buckle down to ensure everything goes right—but birth is just the beginning.
