The influence of basement membrane proteins on cellular barrier properties of primary cultures of porcine brain capillary endothelial cells grown on permeable filter inserts has been investigated. Measurements of transcellular electrical resistance (TER) by impedance spectroscopy were performed with cells cultured on type IV collagen, fibronectin, laminin,(More)
The influence of culture conditions on the development of normal characteristics of the choroid plexus epithelium has been investigated in vitro with respect to polarity, barrier properties, transport, and secretory activity. Withdrawal of serum supplement in the culture medium of cells grown on filters caused morphologically visible changes by an increased(More)
