Figure 7

GFP-expressing HUVECs, indicating extent of network formation. Images are shown for HUVEC/hMSC cocultures on PA-RGDS (a–c) and on TCPs (d–f) and for HUVEC monocultures on PA-RGDS (g–i) and on TCPs (j–l). Fluorescent images show progression of vascular morphogenesis at days 7 (a,d,g,j), 14 (b,e,h,k), and 21 (c,f,i,l) post cell-seeding.
