Impacts of chitosan oligosaccharide (COS) on angiogenic activities

It has been proved that chitosan oligosaccharide (COS) has a more favorable therapeutic applications such as wound healing and anti-tumor treatment, and can affect angiogenesis. For better understanding the effect of COS on angiogenic activities at cellular level, COS with different concentration and degree of polymerization (DP) were used to culture human umbilical vein endothelial cells (HUVECs) in this work. Cell proliferation activity, cell...
