abstract due to their mulitpotency, mesenchymal stem cells (mscs), have the ability to proliferate and differentiate into multiple mesodermal tissues. the aim of this study was to isolate mscs from human umbilical cord (hucmscs) to determine their osteogenic potential on nanofibrous scaffolds. to this end, poly (l-lactic acid) (plla)/nano hydroxyapatite (ha) composite nanofibrous scaffolds were...

Bone diseases such as osteoporosis, delayed or impaired bone healing, and osteoarthritis still represent a social, financial, personal burden for affected patients society. Fully humanized in vitro 3D models of cancellous tissue are needed to develop new treatment strategies meet patient-specific needs. Here, we demonstrate successful cell-sheet-based process optimized mesenchymal stromal cell ...

Scaffold supplements such as nanoparticles, components of the extracellular matrix, or growth factors have been incorporated in conventional scaffold materials to produce smart scaffolds for tissue engineering of damaged hard tissues. Due to increasing concerns on the clinical side effects of using large doses of recombinant bone-morphogenetic protein-2 in bone surgery, it is desirable to devel...

Peripheral blood mesenchymal stem cells (PBMSCs) may be easily harvested from patients, permitting autologous grafts for bone tissue engineering in the future. However, the PBMSC's capabilities of survival, osteogenesis and production of new bone matrix in the defect area are still unclear. Herein, PBMSCs were seeded into a nanofiber scaffold of self-assembling peptide (SAP) and cultured in ost...

In this study, we designed a chitosan/alginate/hydroxyapatite scaffold as a carrier for recombinant BMP-2 (CAH/B2), and evaluated the release kinetics of BMP-2. We evaluated the effect of the CAH/B2 scaffold on the viability and differentiation of bone marrow mesenchymal stem cells (MSCs) by scanning electron microscopy, MTS, ALP assay, alizarin-red staining and qRT-PCR. Moreover, MSCs were see...

Mechanical stimulus has been identified for a long time as a key player in the adaptation of the musculo-skeletal tissues to their function. Mechanical loading is then an intrinsic variable to be considered when new developments are proposed in bone tissue engineering. By combining structural biomechanics and mechanotransduction aspects, a new paradigm is presented for bone tissue engineering. ...

Abstract Due to their mulitpotency, Mesenchymal stem cells (MSCs), have the ability to proliferate and differentiate into multiple mesodermal tissues. The aim of this study was to isolate MSCs from human Umbilical Cord (hUCMSCs) to determine their osteogenic potential on nanofibrous scaffolds. To this end, Poly (L-lactic acid) (PLLA)/Nano hydroxyapatite (HA) composite nanofibrous scaffolds were...

Bone scaffolds play an important role in promoting the healing of large bone defects. However, type scaffold material, drug loaded into scaffold, and method preparation have a significant impact on scaffold's properties. In this study, we developed composite comprising sodium alginate (SA), chitosan (CS), hydroxyapatite (HA). The stent carries vascular endothelial growth factor (VEGF), wrapped ...

Bone tissue reconstruction with extensive damage is one of the challenges for dentists because its healing process bone tissue. graft gold standard repair. However, use has a limited amount produced. Tissue engineering latest method in terms regeneration. three main components, first stem cells that have self renewal ability and multineage differentiation, second bioreactor / growth factor, the...
