Rat Choroid Plexus

The choroid plexus of adult Wistar Rats were dissected from the fourth ventricle to give a primary culture. This primary culture was then immortalized by transfection with the TSori minus adenovirus (a replication deficient adenovirus containing SV40 large T antigen). Sub-cloning of the immortalised cells was performed by selecting for clones which exhibited calcium ion release in response to vasopressin, angiotensin, bradykinin, serotonin or endothelin stimulation. The sub-clone which exhibited the largest response to all five hormones was selected and sub-cultured on to become RCP.
