Reelin immunoreactivity in lymphatics and liver during development and adult life.
Reelin, a glycoprotein secreted by Cajal-Retzius cells, is crucial for cortex lamination and cell positioning. Some peripheral reelin expression has also been reported. Here we describe in developing rat and human and in adult rat very definite reelin immunolocalization in two cell types. Reelin was present in endothelial cells of lymphatic vessels, but not of blood vessels. Reelin was also detected in stellate (Ito) cells of the liver as shown by immunoelectron microscopic examination. The immunlocalization observed in adult tissues indicates a broader role of reelin beyond its previously demonstrated role in neuronal development.
