| 英文摘要 | An osteoblast-laden nanocomposite hydrogel construct, based on polyethylene glycol diacrylate (PEGDA)/laponite XLG nanoclay (Clay)/hyaluronic acid sodium salt (HA) bio-inks, was developed by a two-channel three-dimensional bioprinting (3D-bioprinting) method. The novel biodegradable bio-ink A, comprised of a PEG-Clay nanocomposite crosslinked hydrogel, was used to facilitate 3D-bioprinting and enabled the efficient delivery of oxygen and nutrients to growing cells. HA with encapsulated primary rat osteoblasts (ROBs) was applied as bio-ink B with a view to improving cell viability, distribution uniformity, and deposition efficiency. The cell-laden PEG-Clay constructs not only encapsulated osteoblasts with more than 95% viability in the short term, but also exhibited excellent osteogenic ability in the long term, due to the release of bioactive ions (magnesium ions, Mg2+ and silicon ions, Si4+), which induced the suitable microenvironment to promote the differentiation of the loaded exogenous ROBs, both in vitro and in vivo. This 3D-bioprinting method holds much promise for bone tissue regeneration in terms of cell engraftment, survival, and ultimately long-term function. |
