Laser-Assisted Bioprinting for Bone Repair.

Bioprinting is a novel technological approach that has the potential to solve unmet questions in the field of tissue engineering. Laser-assisted bioprinting (LAB), due to its unprecedented cell printing resolution and precision, is an attractive tool for the in situ printing of a bone substitute. Here, we describe the protocol for LAB and its use for the in situ bioprinting of mesenchymal stromal cells, associated with collagen and nanohydroxyapatite, in order to favor bone regeneration in a calvaria defect model in mice.
