Comparison of Proliferation and Osteoblast Differentiation of Marrow-Derived Mesenchymal Stem Cells on Nano- and Micro-Hydroxyapatite Contained Composite Scaffolds
Bones constructed by tissue engineering are being considered as valuable materials to be used for regeneration of large defects in natural bone. In an attempt to prepare a new bone construct, in this study, proliferation and bone differentiation of marrow-derived mesenchymal stem cells (MSCs) on our recently developed composite scaffolds of nano-, micro-hydroxyapatite/ poly(l-lactic acid) were ...
متن کاملEffect of low-level laser irradiation on osteoblast-like cells cultured on porous hydroxyapatite scaffolds.
OBJECTIVE To determine the effect of laser irradiation at a low dose on human osteoblastlike cells. MATERIALS AND METHODS 32 porous hydroxyapatite scaffolds currently used for bone tissue engineering were seeded with MG63 cells and irradiated or not with a GaAlAs diode laser (wavelength 915 nm, dose 2 J/cm2) using different power density and exposure duration. RESULTS After 72-h incubation,...
متن کاملEnhanced osteoblast-like cell adhesion and proliferation using sulfonate-bearing polymeric scaffolds.
Orthopedic malfunction, degeneration, or damage remains a serious healthcare issue despite advances in medical technology. Proactive extracellular matrix (ECM)-mimetic scaffolds are being researched to orchestrate the activation of diverse osteogenic signaling cascades, facilitating osteointegration. We hypothesized that sulfonated functionalities incorporated into synthetic hydrogels would sim...
متن کاملMC3T3-E1 osteoblast attachment and proliferation on porous hydroxyapatite scaffolds fabricated with nanophase powder
Porous bone tissue engineering scaffolds were fabricated using both nano hydroxyapatite (nano HA) powder (20 nm average particle size) and micro HA powder (10 microm average particle size), resulting in sintered scaffolds of 59 vol% porosity and 8.6 +/- 1.9 microm average grain size and 72 vol% porosity and 588 +/- 55nm average grain size, respectively. Scanning electron microscopy was used to ...
متن کاملOsteoblast-Like Cell Behavior on Porous Scaffolds Based on Poly(styrene) Fibers
Scaffolds of nonresorbable biomaterials can represent an interesting alternative for replacing large bone defects in some particular clinical cases with massive bone loss. Poly(styrene) microfibers were prepared by a dry spinning method. They were partially melted to provide 3D porous scaffolds. The quality of the material was assessed by Raman spectroscopy. Surface roughness was determined by ...
