Figure 6: Asymmetrically divided Apr clones, false Aun and Aun–Adiff clones were identified by co-staining TEX14 with GFRA1 and PLZF. (a) GFRA1 asymmetrically positive Apr clones in whole-mount IHC were identified as asymmetrical division by the presence of TEX14. (b) GFRA1 asymmetrically stained Aun clones in whole-mount IHC was identified as false Aun clone by the absence of TEX14 between adjacent GFRA1POS and GFRA1NEG clonal members. (c) a PLZF asymmetrically expressed Aun–Adiff clone in whole-mount IHC was identified as false Aun and Aun–Adiff clone by absence of TEX14 between adjacent Aun and Adiff clonal members. GFRA1POS or PLZFHIGH Aun: red arrows; GFRA1NEG Aun: yellow arrows; PLZFLOW Adiff : green arrows; IB in whole mount IHC: white arrowheads; IB between Aun connected by TEX14 in whole mount IF: white arrowheads; IB between Adiff connected by TEX14 in whole mount IF: green arrowhead; IB between asymmetrical GFRA1 or PLZF cells without TEX14 in whole mount IF– yellow arrowhead. IB: intercellular bridge. Scale bar=25 μm.
