Figure 1: Morphological changes following neuronal induction of ADAS cells. A: Under control conditions (DMEM, 10% FBS, 1% streptomycinpenicillin and 0.1% gentamycin), ADAS cells grow as a monolayer of large, flat cells. B: After 24 h of culture in neuronal induction medium, ADAS cells display cytoplasmic retraction and a spherical cell body appearance. All images were obtained at 200X magnification.
