Saccular intracranial aneurysm (sIA) rupture is often fatal. Rupture-prone sIA walls are infiltrated by macrophages expressing hemoglobin-receptor CD163, suggesting a role for erythrocyte lysis in the degenerative remodeling predisposing to rupture. We therefore studied erythrocyte remnants in 16 unruptured and 20 ruptured sIA walls using histology and immunohistochemistry.

We studied whether TiO2 coating on plastic cell culture dishes could promote proliferation of hMSCs without adverse effects in chondrogenic differentiation. TiO2-films were deposited on polystyrene dishes and glass coverslips using an ultrashort pulsed laser deposition technique.
