Figure 2From: VEGF receptors on PC12 cells mediate transient activation of ERK1/2 and Akt: comparison of nerve growth factor and vascular endothelial growth factorImmunodetection of VEGF receptors expressed on the cell surface of (a-d) proliferating and (e) differentiated PC12 cells. PC12 cells were stained with polyclonal antibodies against (a) VEGFR-1, (b, e) VEGFR-2, and (c) neuropilin-1. The primary antibody was omitted in (d) controls. Differentiated PC12 cells were also immunoreactive for VEGFR-1 and neuropilin-1 (data not shown).Back to article page
