Fig. 7From: SALL4 promotes angiogenesis in gastric cancer by regulating VEGF expression and targeting SALL4/VEGF pathway inhibits cancer progressionCharacterization of exosomes isolated from 293-T cells. A NTA analysis was used to determine the size range of exosomes isolated from 293-T cells. B Exosomes isolated from 293-T cells are shown in a TEM image. C Exosomal markers including CD9, CD63, TSG-101, HSP-70, and ER marker Calnexin were analyzed by Western blotBack to article page
