Fig. 3From: Glycogen synthase kinase 3 promotes multicellular development over unicellular encystation in encysting DictyosteliaPrespore differentiation in sorogens. Pp wild-type and gsk3− sorogens were fixed and stained with rabbit antispore antibodies and FITC-conjugated antirabbit-IgG [39] (a) or only with FITC-conjugated antirabbit-IgG (b). Structures were photographed under dark field (DF) and epifluorescence (Fl), with prolonged exposure for the structures in b. Bar: 0.1 mmBack to article page
