Laser-Assisted Bioprinting (LAB) technology, due to its unprecedented cell printing resolution and precision, is an attractive tool for the in situ printing of a bone substitute. We have previously shown that LAB can be used to induce bone regeneration through the in situ printing of mesenchymal stromal cells, associated with collagen and nano-hydroxyapatite, in a calvaria defect model in mice. In this model, different cell printing geometries proved to impact differently the process of bone tissue regeneration.
