abstract：:Platelet-rich plasma (PRP) contains many growth factors that are involved in tissue regeneration processes. For successful tissue regeneration, protein growth factors require a delivery vehicle for long-term and sustained release to a defect site in order to maintain their bioactivity. Previously, we showed that hepar...
