Study of osteogenic potential of electrospun PCL incorporated by dendrimerized superparamagnetic nanoparticles as a bone tissue engineering scaffold

AbstractNano biphasic calcium phosphate (BCP) particles were synthesized using the sol-gel method. As-prepared BCP particles were combined with poly-L-lactide (PLLA) to fabricate nano-BCP/PLLA composite scaffold through a series of processing steps containing solvent self-diffusion, hot-pressing, and particulate leaching. The composite had a suitable porous structure for bone tissue engineering scaffold. In comparison, micro-BCP/PLLA scaffold was studied as well. Nano-BCP particles were distributed homogeneously in the PLLA matrix, and much more tiny crystallites exposed on the surface of the pore wall. Due to the finer inorganic particle distribution in the PLLA phase and the larger area of the bioactive phase exposed in the pore wall surface, nano-BCP/PLLA scaffold had enhanced compressive strength, good bioactivity, and superior cell viability. A nonstoichiometric apatite layer could be rapidly formed on the surface of nano- BCP/PLLA when soaked in simulated body fluid. The MG-63 cell viability of nano-BCP/PLLA scaffold is significantly higher than that of micro-BCP/PLLA scaffold. Therefore, nano-BCP/PLLA composite may be a suitable alternative for bone tissue engineering scaffold.

In the bone tissue engineering composite scaffolds with osteogenic potential are emerging as the new tool. Here, we investigated the graphene (GP), graphene oxide (GO) andCissusquadrangularis(CQ) callus extract for their spontaneous osteoinductive potential. Electrospun poly ε-caprolactone (PCL) sheets were painted with varying combination GP, GO and CQ solutions as ink. The prepared PCL-GO, PCL-GO-CQ, PCL-GP and PCL-GP-CQ scaffolds were characterized for their physical, mechanical and biological properties. Addition of GO, GP, GO-CQ and GP-CQ to PCL enhanced roughness, wettability, Yield strength and tensile strength, biocompatibility .significantly. Presence of GO and CQ in PCL-GO-CQ scaffolds, while GP and CQ in PCL-GP-CQ scaffolds showed synergistic effect on the biocompatibility, Cell attachment,cell proliferation of human umbilical Wharton’s jelly derived mesenchymal stem cells (hUCMSCs) and their differentiation into osteoblasts by 21stday in culture without osteogenic differentiation media or any growth factors. Same is confirmed by the Alizarin red S staining and Von kossa staining. The combination of PCL-GO-CQ scaffold prepared by novel paint method was found to be the most potential in bone tissue engineering.

Rat Mandible

Although bone marrow–derived mesenchymal stem cells (MSCs) have been extensively explored in bone tissue engineering, only few studies using mesenchymal stem cells from mandible (M-MSCs) have been reported. However, mesenchymal stem cells from mandible have the potential to be as effective as femur-derived mesenchymal stem cells (F-MSCs) in regenerating bone, especially in the orofacial regions, which share embryonic origin, proximity, and accessibility. M-MSCs were isolated and characterized using mesenchymal stem cell–specific markers, colony forming assay, and multi-potential differentiation. In vitro osteogenic potential, including proliferation, osteogenic gene expression, alkaline phosphatase activity, and mineralization, was examined and compared. Furthermore, in vivo bone formations of F-MSCs and M-MSCs in rat critical sized defect were evaluated using microCT and histology. M-MSCs from rat could be successfully isolated and expanded while preserving their MSC’s characteristics. M-MSCs demonstrated a comparable proliferation and mineralization potentials and in vivo bone formation as F-MSCs. M-MSCs is a promising cell source candidate for craniofacial bone tissue engineering.
