TL;DR: The case of an expectant mother who had a febrile illness with rash at the end of the first trimester of pregnancy while she was living in Brazil and revealed microcephaly with calcifications in the fetal brain and placenta is described.
Organogenesis in a dish: modeling development and disease using organoid technologies.
TL;DR: These studies illustrated two key events in structural organization during organogenesis: cell sorting out and spatially restricted lineage commitment, which are recapitulated in organoids, which self-assemble to form the cellular organization of the organ itself.
