Introduction: Wnt-1 is capable of inducing metanephric mesenchyme to undergo tubulogenesis. A relationship between the degree of cystogenesis and reduced E-cadherin (E-cad) expression was described. Syndecan-1 (Sdc-1) has a critical role in kidney development. Materials and Methods: Ten multicystic dysplastic kidneys (MCDKs) were stained with hematoxylin and eosin and immunohistochemistry was performed using Wnt-1, E-cad and Sdc-1 antibodies. Eight unaffected kidneys were used as controls. Results: Strong Wnt-1 immunostaining occurred inside cystic/tubular epithelial cells and in blastematous foci. An immunoreaction was observed in glomerular epithelial cells. In controls, just weak cytoplasmic Wnt-1 positivity was seen in tubular epithelial cells. E-cad reaction was negative in MCDKs while strong immunostaining was common in tubular cells of controls. A strong Sdc-1 immunoreaction depicted …
