Bone Repair Material

There are usually two forms of bone repair materials, block and granular, for common clinical use. This paper describes a novel injectable material, nano-HA/collagen/alginate (nHAC/Alg) composite biomaterial, including its preparation and evaluationsin vitro. Based on the idea of bionics and the study of collagen/calcium phosphate salt composite materials, the injectable bone repair material was developed. Then, human bone marrow stem cells (hBMSCs) were cultured on the nHAC/Alg material. The cell attachment, proliferation, and differentiation were evaluated with inverted microscope, scanning electron microscope, laser scanning confocal microscope, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) analysis, and alkaline phosphatase (ALP) test. The results showed that nHAC/Alg not only had no negative effect on cellular functions but also promotes cell proliferation and differentiation into osteogenic cells, which suggests that the nanoscaled injectable bone repair material has good clinical application prospects for bone repair.

Background: As the major inorganic component of natural bone, nano-hydroxyapatite (n-HA) on its own is limited in its use in bone repair, due to its brittleness. Chitosan (CS) and sodium alginate (SAL) are used to reduce its brittleness and tendency to degradation. However, the compressive strength of the composite is still low, and its biological performance needs further study. Methods: Nano-hydroxyapatite/sodium alginate/chitosan (n-HA/SAL/CS) composite was prepared via an in situ synthesis method. Further, we prepared the n-HA/SAL/CS self-setting bone repair material by mixing n-HA/SAL/CS powder with a curing liquid (20 wt.% citric acid). In addition, the in vitro bioactivity and cell cytotoxicity were also explored. Results: Transmission electron microscopy photos revealed that the n-HA crystals were uniformly distributed throughout the polymer matrix. Infrared IR spectroscopy indicated that the HA interacted with the COO− of SAL and NH2− of CS. The compressive strength of the n-HA/SAL/CS bone cement was 34.3 MPa and matched the demands of weight-bearing bones. Soaking in vitro in simulated body fluid demonstrated that the composite material had reasonably good bioactivity, while cytotoxicity tests indicated that the n-HA/SAL/CS cement could promote cell proliferation and was biocompatible. Conclusions: Compressive strength of n-HA/SAL/CS can satisfy the needs of cancellous bone, and in vitro bioactivity and cytotoxicity tests results indicated that the n-HA/SAL/CS composite could act as an optimal bone repair material.
