text: The process of creating a 3-D organ with stem cells is thought to not be possible without the structural support of a donor organ. However, new studies are being conducted that discuss research on the process of 3-D bioprinting organs. The process of 3-D Bioprinting includes combining cells and growth factors to create a bioink, then using that bioink to print individual layers of tissue. Research is being done to find ways to use the formulated bioink to print organs that have the same structural support of donor organs without the need for donors. While currently there have not been experimental success with printing structural organs, there has been success with using bioink for printing tissue layers. A method for creating gelatin based vascularized bone equivalents has shown to be successful in a small scale experiment, but it has not been used clinically.
