  • Preparation method of gradient mineralized cancellous bone matrix material
    Patent number: 11684696
    Abstract: A gradient mineralized cancellous bone matrix material and a preparation method thereof are provided, and the preparation method includes: processing naturally-derived bone tissue with an immunogenicity removal treatment for decellularization, and processing an obtained decellularzed bone with a gradient demineralization treatment to obtain the gradient mineralized cancellous bone matrix material. The present invention expands a porosity of the bone matrix material and a collagen exposure degree on a surface thereof, which effectively releases growth factors and improves adhesion of the material to the cells, so as to up-regulate genes and proteins related to cell regeneration.
    Type: Grant
