Abstract |
The advancement of tissue and organ engineering lead to bioprinting tissue constructs with cells and cell-laden materials. Bioprinting is an attractive alternative for acellular 3D printing of tissues since cells and cell-laden materials can be precisely positioned to physiologically mimic human tissues. Despite the rapid progress in bioprinting methods, fabrication of cell-laden tissues with microvascular structure and micropores still remained a challenge. Here, we report a method for bioprinting of cell-laden tissue constructs with microvascular structures and micropores. Sucrose is added to increase the viscosity and the printability of the bioink, as well as to create micropores which function as microvasculature. Micropores were fabricated in bioprinted constructs by leaching sucrose crystals after the bioprinting process. These microvascular structures and micropores could improve the fluid flow between cells and the surrounding tissue thereby promoting the cell viability. We studied the effect of micropores on cell viability and diffusion profile in microporous tissue constructs. |
