Bioprinting of stem cell expansion lattices.

ABSTRACT: Stem cells have great potential in regenerative medicine, with neural progenitor cells (NPCs) being developed as a therapy for many central nervous system diseases and injuries. However, one limitation to the clinical translation of stem cells is the resource-intensive, two-dimensional culture protocols required for biomanufacturing a clinically-relevant number of cells. This challenge can be overcome in an easy-to-produce and cost-effective 3D platform by bioprinting NPCs in a layered lattice structure. Here we demonstrate that alginate biopolymers are an ideal bioink for expansion lattices and do not require chemical modifications for effective NPC expansion. Alginate bioinks that are lightly crosslinked prior to printing can shield printed NPCs from potential mechanical damage caused by
