title: [Current findings on the asymmetric growth of the mullerian tract in female chick embryos].
abstract: Shape and orientation of the mesothelial cells were examined in the mullerian ducts of 8, 13 and 15 day female chick embryos with the scanning electron microscope. The observed evolution in the pattern of these cells likely reflects the mechanical conditions to which these organs are subjected during embryonic development: stretching for the left duct, slackening for the right duct. These observations, together with data concerning growth of these organs, suggest that topographical relationships between cells, which in this system result from mechanical factors, play an important role in controlling cell proliferation.
