제목 Genetically engineered phage as versatile nanoink for 3D bioprinting
초록  Bioprinting is a promising technology for producing tissue-mimetic 3-D structures using cell-containing hydrogels. Choosing the right cell-containing “bioink” material is the most essential step for fabricating 3-D constructs with a controlled mechanical and biochemical microenvironment that can lead to successful tissue regeneration. Here, we demonstrate that the genetically engineered M13 phage holds great potential for use as a versatile nanoink for printing 3-D cell-containing matrices. In particular, M13 phages displaying integrin-binding (GRGDS) and calcium-binding (DDYD) domains on their surface were blended with alginate to form Ca2+-crosslinked hydrogels. The MC3T3-E1 cells within these scaffolds showed enhanced proliferation and differentiation rates that increased proportionally with the concentration of phages in the 3-D matrices compared with the rates of cells in pure alginate scaffolds.
