Abstract: A hydrogel for cell-laden bioprinting, bioink, and a preparation method and an application thereof, relates to the technical field of biomedical polymer hydrogels. The hydrogel for cell-laden bioprinting is polymer gel formed by adding a cell-specific material into a matrix of alginate and gelatin and crosslinking and curing, wherein the cell-specific material is polypeptide selected according to different laden cells. The structures printed using the hydrogel may have the advantages such as adjustable mechanical properties, adjustable porosity, high biocompatibility, high printing accuracy, and high customizability, which may widely support the printing of human tissues and organs such as spinal cord, cartilage, and heart, and has good prospects for applications in tissue repair, organ transplantation and so on.

Abstract: Provided are a data processing method and apparatus, an electronic device and a storage medium. The data processing method comprises: according to a reference depth value and an actual depth value of a key point of a target in an image, converting first 2D coordinates of the key point into second 2D coordinates, wherein the second 2D coordinates and the reference depth value constitute a first 3D feature of the key point; and based on the first 3D feature, obtaining a 3D posture of the target.
