Injectable shear-thinning hydrogels for delivering osteogenic and angiogenic cells and growth factors

Abstract: Bone nonunion may occur when the fracture is unstable, or blood supply is impeded. To provide an effective treatment for the healing of nonunion defects, we introduce an injectable osteogenic hydrogel that can deliver cells and vasculogenic growth factors. We used a silicate-based shear-thinning hydrogel (STH) to engineer an injectable scaffold and incorporated polycaprolactone (PCL) nanoparticles that entrap and release vasculogenic growth factors in a controlled manner. By adjusting the solid composition of … Show more

“…Their handheld skin bioprinter showed promising capability to be used in large‐scale skin wounds. More recently, Alarçin et al developed a similar handheld system to inject silicate‐based shear‐thinning hydrogels (STHs) encapsulating vasculogenic growth factor‐loaded PCL nanoparticles (Figure E,F) . Through deposition using a multimaterial, single‐nozzle printhead, they were able to bioprint different STHs directly into a bone defect (Figure G).…”

“…Notably, particle sizes were increased with an increase in drug amount probably due to more viscous aqueous phase based upon high amount of oxaceprol resulted in incomplete dispersion of the phases (Mainardes & Evangelista, ). Zeta potential values of particles were in range between −23 and −21 mV indicating the stability of nanoparticles due to electrostatic repulsion forces which prevent particle aggregation (Alarçin et al., ).…”

“…OXC loaded PLGA nanoparticles were fabricated by double‐emulsion (W1/O/W2) solvent evaporation method, described elsewhere, using different amounts of polymer and drug (Alarçin et al., ). Briefly, a 2 ml aqueous internal phase containing 30, 60, or 150 mg OXC was emulsified in a 5 ml methylene chloride solution containing 300 mg PLGA by homogenization (IKA T18 digital ULTRA‐TURRAX, Germany) at 12,000 rpm for 3 min.…”

“…These devices provide advantages for translation such as user‐friendly designs, low costs and ease of sterilization. Initial work has demonstrated the potential of these handheld direct‐write devices to be used for treatment of chondral injuries, bone nonunions, and skin wounds . The manually operated tools provide the ability to deposit bioinks in these injury sites without the need for expensive, intrusive hardware in the operating room.…”
