Living GP8 rat cerebral endothelial cells

Before (left) and after (right) chemical treatment with mannitol.

Living GP8 rat cerebral endothelial cells cultured until confluency in a petri dish coated with rat tail collagen in DMEM/F12 (Dulbecco's Modified Eagles Medium with F12 salt), supplemented with 12% PDS (Plasma Derived Serum). They were imaged at a temperature around 31°C. The left image is before chemical treatment. After imaging, without moving the sample and the AFM head, the medium was exchanged with the same solution, containing 0.55 M mannitol which has a reversible hyperosmotic effect at this concentration. After changing the solution, the same cells were imaged to see the mannitol induced changes (right image). 40µm scans.
