MagnetOs for predictable fusions

A bone graft like no other

MagnetOs is a bone graft like no other: thanks to its NeedleGrip surface technology, it grows bone even in soft tissues.* This surface technology provides traction for our body’s vitally important ‘pro-healing’ immune cells (M2 macrophages).†‡1,2

This in turn, unlocks previously untapped potential to stimulate stem cells – and form new bone throughout the graft.†§3-6

The growing body of science behind NeedleGrip is called osteoimmunology. But for surgeons and their patients it means one thing: a more predictable fusion.¶5,6

MagnetOs Mechanism of Action

Kuros Biosciences MagnetOs bone graft Mechanism of action Polarization

1. Polarize

Circulating immune cells (monocytes) differentiate into macrophages that are subsequently polarized, by the submicron needle-shaped features of MagnetOs’ Needlegrip surface.

As a result, they become the pro-healing, anti-inflammatory M2 macrophage phenotype.†2,6

2. Regenerate

In natural bone homeostasis, it is well established that M2 macrophages play a critical role.

M2 macrophages communicate with local stem – and progenitor cells via secretion of regenerative signaling factors, including osteoactivin and BMP-2.6,12,13

These signaling factors induce mesenchymal stem cells to migrate, proliferate, and differentiate into osteoblasts that lay down osteoid.6,13-15

Endothelial cells are stimulated to form capillaries that deliver nutrients and yet more osteogenic cells to the site of repair.6,13

3. Propagate

Non-unions tend to happen in the core of large-span defects, as seen in spinal fusions.

NeedleGrip propagates bone in this core region – by interacting directly and indirectly with circulating osteogenic cells – rather than only from the outside-in via creeping edge repair.†‡2-5

MagnetOs:
the evidence

MagnetOs is proven to be equivalent to the gold standard of autograft for spinal fusions.2,4,5 It has been used in more than 25,000 fusion surgeries to date and is supported by an unprecedented blend of scientific, pre-clinical and clinical studies through Project Fusion: our global research program, where science and clinical evidence meet.

Kuros is dedicated to reliably translate evidence from benchtop through to patient. Review our extensive list of studies, including results from our latest level I clinical trial, to see how.
