The influence of fibroblast on the arachnoid leptomeningeal cells in vitro

Fibroblasts influence arachnoid cell's mannitol transport likely via soluble factors. While the arachnoid cells did not change morphologically, cell growth was influenced. Over time, the cells had profound changes in transport and motility. The immortalized arachnoid cell/fibroblast culture system provides a unique model mimicking the pathologic event of leptomeningeal scarring.
