Hyperacute Serum Has Markedly Better Regenerative Efficacy Than Platelet-Rich Plasma in a Human Bone Oxygen-Glucose Deprivation Model

Abstract

Aim: Platelet-rich plasma (PRP) and hyperacute serum (HAS) were compared in a novel human model of ex vivo bone damage induced by oxygen-glucose deprivation (OGD).

Materials & methods: Osteoarthritic subchondral bone pieces were harvested from discarded femoral heads during hip replacement surgery and subjected to transient OGD.

Results: Proteome profiling revealed that PRP is more angiopoietic, whereas HAS is more antiangiopoietic in composition. However, treatment of OGD-exposed bone with multiple PRP preparations had no effect on cell counts, whereas HAS restored cell proliferation capacity and rescued viable cell number following OGD.

Conclusion: A similar pro-proliferation effect was observed with recombinant growth factors, indicating that HAS may be an alternative agent for enhancing the regeneration of damaged bone cells.

Keywords: blood fractions; bone necrosis; femoral head; growth factors; ischemia.
