Dear Colleagues

For the advancement of bioprinting, developments of novel methods, processes, and ink materials that will contribute to creating functional 3-dimensional tissues are essential. This special issue solicits papers dealing with these topics. In other words, the papers describing the function of the cell-laden 3D constructs prepared based on the preceding methods, processes, and materials are not welcome. The data on the detailed function of the cells in the printed constructs is not necessary except for the cytocompatibility studies such as the viability and growth of the laden cells. The papers will be evaluated based on the novelty of the method, process, and ink materials.
