Continuing growth and development of the third-trimester human placenta.
Two hundred and nineteen human placentae of well ascertained gestational age were measured for weight and nuclear number. Contrary to previous reports, analysis of the results showed no faltering in either parameter, however expressed. The placentae from babies exhibiting intrauterine growth retardation were appropriate to the size of the babies. However else the placenta ages it does not do so in respect of the rate of increase in the number of its nuclei.
