一般描述
3D bioprinting is the printing of biocompatible materials, cells, growth factors, and the other supporting materials necessary to yield functional complex living tissues. 3D bioprinting has been used to generate several different types of tissue such as skin, bone, vascular grafts, and cartilage structures. Based upon the desired properties, different materials and formulations can be used to generate both hard and soft tissues. While several 3D printing methods exist, due to the sensitivity of the materials used, extrusion-based methods with bioinks are most commonly employed.
应用
Gelatin methacryloyl (GelMA) is a polymerizable hydrogel material derived from natural extracellular matrix (ECM) components. Due to its low cost, abundance, and retention of natural cell binding motifs, gelatin has become a highly sought material for tissue engineering applications. Alginate is a naturally occurring polymer widely applied for bioprinting applications as its printability can be easily modified by altering the polymer density and crosslinking with the addition of calcium chloride (CaCl2). Alginate is often combined with gelatin to facilitate cell adhesion and differentiation. The addition of photocrosslinkable methacrylamide functional groups in GelMA allows the synthesis of biocompatible, biodegradable, and non-immunogenic hydrogels that are stable in biologically relevant conditions and promote cell adhesion, spreading, and proliferation. In addition to fast gelation, the methacrylamide functional group can also be used to control the hydrogel physical parameters such as pore size, degradation rate, and swell ratio. Temporal and spatial control of the crosslinking reaction can be obtained by adjusting the degree of functionalization and polymerization conditions, allowing for the fabrication of hydrogels with unique patterns, 3D structures, and morphologies. Gelatin methacrylate bioinks have been used for 3D bioprinting with high printing resolution, shape fidelity and cell viability. Gelatin methacrylate based bioinks have been used to bioprint osteogenic, chondrogenic, hepatic, adipogenic, vasculogenic, epithelial, endothelial, cardiac valve, skin, tumor and other tissues and constructs. Gelatin and alginate-containing bioinks have been used for bioprinting of 3D constructs with various cell types including human mesenchymal stem cells (hMSC), embryonic stem cells (ESC), human umbilical vein endothelial cells (HUVEC), fibroblasts, and cancer cells.
