Different types of HGs were fabricated with VEGF containing PEGylated fibrinogen and hyaluronic acid for myocardial infarction [29,30], hyaluronic acid for bioprosthetic heart valves [31], decellularized adipose tissue for angiogenesis [32], and fibrinogen-alginate for plasticity in an injured spinal cord [33]. This evidence concerns the gene VEGFA and myocardial infarction.
