SAN DIEGO: ELSEVIER, 2014. p.545-556.978-0-12-394445-0https://observatorio.fm.usp.br/handle/OPI/7119Stereology provides a set of efficient and unbiased or minimally biased tools for quantifying functionally relevant aspects of the three-dimensional morphology of the placenta. The quantities include volumes, surface areas, lengths, and numbers and can be estimated for different levels of structural organization, from whole organ to cell and molecule. By paying careful attention to how the placenta is sampled for microscopic examination, stereological tools can be used to shed light on relevant processes, such as placental growth and development, oxygen transport, fetoplacental angiogenesis, and trophoblast turnover. Here, we review stereological best practices as applied to the mouse placenta during normal pregnancy and after experimental manipulation.engrestrictedAccessFetal capillariesIntervascular membraneJunctional zoneLabyrinthMaternal blood spaceMicroscopyStereologyTrophoblastbookPartCopyright ELSEVIER10.1016/B978-0-12-394445-0.00046-1
