| 摘要 |
The invention provides methods and systems for selectively upregulating the expression of a VEGF receptor in a cell using a synthetic nanofibrillar article. Exemplary embodiments relate to the upregulation of the VEGF receptor Flk-1 in endothelial cells. Cells having the selectively-upregulated VEGF receptor can be used in processes such as cell culturing, tissue engineering, cellular therapy, and drug discovery.
