Figure 1
From: VEGF121b and VEGF165b are weakly angiogenic isoforms of VEGF-A
VEGF-A transcripts generated by mRNA alternative splicing. Exon organization of VEGF-A gene (A). Exons 1 to 5 are included in all isoforms (A-C). The 3' alternative exons 8 and 8b, of the same length in base pairs, are differentially included in the "classical" family of VEGF-A isoforms (B) or the novel family of "b isoforms" (VEGFxxxb) (C).
