title: [Identification of components of the extracellular matrix in trophoblastic cell columns of human placenta].
abstract: The distribution of five components of the extracellular matrix was studied in human placenta (9-12 and 39-40 weeks of gestation) by an indirect immunofluorescence method with polyclonal monospecific antibodies. In trophoblastic cell columns fibronectin, collagen types IV and V formed homogeneous deposits, whereas collagen types I and II comprised small conglomerates and scanty, discrete granules. The origin of these macromolecules was discussed.
