Embodiment Construction
[0035] Below in conjunction with accompanying drawing, the present invention will be further described, but therefore the present invention is not limited among the scope of described embodiment:
[0036] see figure 1: The intravascular stent covered by the transgenic cells is provided with a treatment layer 1 on the metal surface of the traditional bare metal stent 4, an adhesion matrix coating 2 is arranged on the treatment layer 1, and a cell coating 3 is established on the adhesion matrix coating , Cell Coating 3 was obtained by stably transfecting cells with the gene of interest.
[0037] Wherein, the treatment layer 1 is a low-temperature plasma coating, and its surface roughness is 5-15 μm. Adhesion matrix coating 2 is one of protein coating and sequence peptide coating. The protein is one or more of proteins with the function of promoting cell adhesion, such as gelatin, type IV collagen, polylysine, and fibronectin. Sequence peptides are sequence peptides with the f...
