Color-Coded Imaging Of Vessel Anastomosis In Vivo Using Rfp And Cfp Transgenic Mice
CANCER RESEARCH(2014)
Abstract
Proceedings: AACR Annual Meeting 2014; April 5-9, 2014; San Diego, CA
We previously report the development of a color-coded imaging model that can visualize the anastomosis between blood vessels of red fluorescent protein (RFP)-expressing vessels in Gelfoam® previously vascularized in RFP transgenic mice and blood vessels of nestin-driven green fluorescent protein (ND-GFP) mice that express GFP in nascent vessels (Anticancer Res. 33: 3041-3046, 2013). In the present study, fourteen days after transplantation into RFP transgenic nude mice, the Gelfoam® was removed and re-transplanted into the subcutis on the flank of cyan fluorescent protein (CFP) transgenic mice. Skin flaps were made and anastomosis between the CFP-expressing vessels and RFP blood vessels in the Gelfoam® was imaged 14 and 21 days after re-transplantation. The results presented in this and our previous report suggest a new paradigm of visualizing blood vessel anastomosis and its implications for tumor angiogenesis.
