The ability to generate and maintain stable in vitro cultures of mouse
endothelial cells (ECs) has great potential for genetic dissection of the
numerous pathologies involving vascular dysfunction as well as therapeutic
applications. However, previous efforts at achieving sustained cultures of
primary stable murine vascular cells have fallen short, and the cellular
requirements for EC maintenance in vitro remain undefined. In this study, we have
generated vascular ECs from mouse embryonic stem (ES) cells and show that active
Akt is essential to their survival and propagation as homogeneous monolayers in
vitro. These cells harbor the phenotypical, biochemical, and functional
characteristics of ECs and expand throughout long-term cultures, while
maintaining their angiogenic capacity. Moreover, Akt-transduced embryonic ECs
form functional perfused vessels in vivo that anastomose with host blood vessels.
We provide evidence for a novel function of Akt in stabilizing EC identity,
whereby the activated form of the protein protects mouse ES cell-derived ECs from
TGF?-mediated transdifferentiation by downregulating SMAD3. These findings
identify a role for Akt in regulating the developmental potential of ES
cell-derived ECs and demonstrate that active Akt maintains endothelial identity
in embryonic ECs by interfering with active TGF?-mediated processes that would
ordinarily usher these cells to alternate fates.
