80–90% of cancer are carcinomas, or cancers that form from epithelial tissue. This tissue is not vascularized, which prevents tumors from growing greater than 2mm in diameter without inducing new blood vessels. Angiogenesis is upregulated to feed the cancer cells, and as a result the vasculature formed differs from that of normal tissue. WebIn order to improve active tumor targeting, tumor cell uptake efficiency and circulation time of doxorubicin (DOX) in vivo, we constructed a cleavable PEGylated hyaluronic acid nano …
