A Covalently Crosslinked Bioink Used In
Three-dimensional Cell Cultures of 3D
Bioprinting

A three-dimensional (3D) cell culture is an artificially created environment in which
biological cells are permitted to grow or interact with their surroundings in all three
dimensions. A 3D cell culture allows cells in vitro to grow in all directions, similar to how
they would in vivo. Compared with 2D cell culture, in vitro 3D cell models can better
recapitulate aspects in vivo organ environment. At present, the production of 3D cell
models in vitro remains challenging.

There is a versatile bio-ink consisting of a 4-arm PEG based polymer with
distal maleimide derivatives as the main ink component, and a bis-thiol species as the
activator that can cross-link the polymer to form a hydrogel in less than a second. Rapid
gelation makes the polymer system compatible with 3D bioprinting.
