The inability to vascularize engineered organs and revascularize areas of
infarction has been a major roadblock to delivering successful regenerative
medicine therapies to the clinic. These investigations detail an isolated human
extracellular matrix derived from the placenta (hPM) that induces vasculogenesis
in vitro and angiogenesis in vivo within bioengineered tissues, with significant
immune reductive properties. Compositional analysis showed ECM components
(fibrinogen, laminin), angiogenic cytokines (angiogenin, FGF), and immune-related
cytokines (annexins, DEFA1) in near physiological ratios. Gene expression
profiles of endothelial cells seeded onto the matrix displayed upregulation of
angiogenic genes (TGFB1, VEGFA), remodeling genes (MMP9, LAMA5) and vascular
development genes (HAND2, LECT1). Angiogenic networks displayed a time dependent
stability in comparison to current in vitro approaches that degrade rapidly. In
vivo, matrix-dosed bioscaffolds showed enhanced angiogenesis and significantly
reduced fibrosis in comparison to current angiogenic biomaterials. Implementation
of this human placenta derived extracellular matrix provides an alternative to
Matrigel and, due to its human derivation, its development may have significant
clinical applications leading to advances in therapeutic angiogenesis techniques
and tissue engineering.
