Multi-dimensional composite scaffold with multiple growth factors capable of being released in gradient manner and preparation method thereof |
| abstract |
The invention discloses a multi-dimensional composite bracket with multi-growth factors capable of being released in a gradient manner and a preparation method thereof. The scaffold realizes the spatial-temporal distribution and gradient release control of various cell growth factor components, and after the scaffold is implanted into a human body, the scaffold is compounded with growth factors with different concentrations and different gradients, so that the scaffold releases various cell growth factors in a gradient manner in the degradation process, the physiological process of in vivo bone defect repair and reconstruction is matched and accelerated, and the bottleneck problem of bone defect repair in clinic is solved. |
