简介
Dermatopontin (DPT) is a matricellular protein with cardinal roles in cutaneous wound healing. The protein is also reported to be altered in various anomalies including cancer. The present study is aimed to unravel the role of DPT in angiogenesis which is imperative in many physiological and pathological processes. DPT’s capabilities on promoting angiogenesis were assessed using various in vitro and ex vivo systems. The results indicated that DPT enhances cell motility and induces lamellipodia formation in endothelial cells. Additionally, we noticed that DPT stimulates tube formation in endothelial cells when plated on a matrigel substrate. However, it was observed that DPT had no effect on the proliferation of endothelial cells even at higher concentrations and prolonged treatment periods. Additional experiments on CAM and aortic arch assays apparently depicted that DPT promotes neovascularisation and …
