In addition, this cell line is also useful in pathological conditions such as hydrocephalus, arachnoid cysts, or other disorders. It has the ability to form tight junctions as measured by TEER and radiochemical (i.e. TEER value of 193 SEM ohm-cm² is comparable to 206 SEM ohm-cm² value of that of Caco-2 cells).
