Fig. 2From: Development of an In Vitro 3D Model for Investigating Ligamentum Flavum HypertrophyLive and dead cell staining of LF spheroids in spheroids with different cell concentrations. Spheroids were cultured for 14 days. Live and dead staining on days 7 and 14. BF represents a bright-field image. Live cells exhibit intense green fluorescence. Dead cells exhibit red fluorescence.
