title: Synthesis and distribution of laminin-related polypeptides in early amphibian embryos.
abstract: Western blotting experiments carried out with several heterospecific antibodies against mouse-derived laminin allowed the identification of four laminin-related polypeptides in early Pleurodeles waltlii embryos. Synthesis of all four polypeptides was detected from the early blastula stage to late gastrula stage. Immunofluorescent staining with anti-laminin and anti-fibronectin antibodies provided evidence for a close association of these laminin-related polypeptides with the fibronectin fibrillar network.
