The study described a novel bone tissue scaffold fabricated by computer-aided, air pressure-aided deposition system to control the macro- and microstructure precisely. The porcine bone marrow stem cells (PBMSCs) seeded on either mPEG-PCL-mPEG (PCL) or mPEG-PCL-mPEG/hydroxyapatite (PCL/HA) composite scaffold were cultured under osteogenic medium to test the(More)
Bone tissue engineering (BTE) is now a promising research issue to improve the drawbacks from traditional bone grafting procedure such as limited donor sources and possible complications. Stem cells are one of the major factors in BTE due to the capability of self renewal and multi-lineage differentiation. Unlike embryonic stem cells, which are more(More)
BACKGROUND Although recent evidence suggests a controversy effect of steroids in the management of indirect traumatic optic neuropathy (TON), steroid pulse therapy remains one of the reasonable treatments for patients with indirect TON. It is thought that microcirculatory spasms, edema, and nerve cell necrosis can be prevented or reduced by large doses of(More)
BACKGROUND This study examined whether a combination of autologous platelet-rich fibrin glue (PRFG) with mesenchymal stem cells (MSCs) and MEDPOR as guided tissue regeneration (GTR) could act as an osteogenic substitute and whether this treatment yields faster new bone formation than MEDPOR alone or PRFG plus MSC. MATERIAL MSCs were harvested and isolated(More)
Breast reconstruction in female Poland anomaly remains a surgical challenge with variable chest wall deformity and nipple position. Pedicled latissimus dorsi myocutaneous flap with implant reconstruction may have several drawbacks and complications. Free deep inferior epigastric flap (DIEP) flap is a reliable option for postmastectomy breast reconstruction,(More)
The current study aimed to fabricate three-dimensional (3D) polycaprolactone (PCL), polycaprolactone and β-tricalcium phosphate (PCL-TCP) scaffolds via a selective laser-sintering technique (SLS). Collagen type I was further coated onto PCL-TCP scaffolds to form PCL-TCP-COL scaffolds. The physical characters of these three scaffolds were analysed. The(More)
Due to the natural properties of fat, fat grafting remains a popular procedure for soft tissue volume augmentation and reconstruction. However, clinical outcome varies and is technique dependent. Platelet-rich plasma (PRP) contains α-granules, from which multiple growth factors such as platelet-derived growth factor, transforming growth factor-β, vascular(More)
This study describes an injectable, thermo-responsive hyaluronic acid-g-chitosan-g-poly(N-isopropylacrylamide) (HA-CPN) copolymer for bone tissue engineering. The wettability, temperature-dependent change of water content, and volume of HA-CPN hydrogel were measured, together with its biocompatibility in vitro and in vivo. The dried hydrogel morphology(More)
To provide osteoblast cells with a three-dimensional environment closer to bone matrix, an engineered construct mimicking bone components have been designed and evaluated. A biocompatible injectable thermo-responsive hydrogel, hyaluronic acid-g-chitosan-g-poly (N-isopropylacrylamide) (HA-CPN), was used as a biomimetic organic gel matrix while embedded(More)
Macroporous elastic scaffolds containing gelatin (4% or 10%) and 0.25% hyaluronic acid (HA) were fabricated by cryogelation for application in adipose tissue engineering. These cryogels have interconnected pores (∼200 μm), high porosity (>90%) and a high degree of cross-linking (>99%). The higher gelatin concentration reduced the pore size, porosity and(More)
