From: Retention of progenitor cell phenotype in otospheres from guinea pig and mouse cochlea
Images of analyses taken at a Zeiss Axiovert 40C inverted microscope and an Axiocamera MRC5 (Zeiss, Germany) of spheres observed with phase contrast while culturing of dissociated mouse or guinea pig cochleas, with either bFGF or TGFα, as indicated. P0 and P1 indicate primary culture and first subculturing, respectively. Arrows indicate otospheres obtained from guinea pig. Scale bar 50 μm.
