Fig. 3From: The availability of the embryonic TGF-β protein Nodal is dynamically regulated during glioblastoma multiforme tumorigenesisNodal protein co-localizes with different endosomal vesicles depending on the differentiation status of GBM cells. Representative images of Nodal immunostaining with endosomal markers. In OB1 stem cells, Nodal co-localized with both early (EEA1 and Rab5) and late (Rab7 and Rab11) endosomes. In contrast, in differentiated OB1 cells, Nodal immunostaining was mostly co-localized with late (Rab7 and Rab11) endosomal vesiclesBack to article page
