Fused deposition modeling has been used to fabricate three-dimensional (3D) scaffolds for tissue engineering applications, because it allows to tailor their pore network. Despite the proven flexibility in doing so, a limited amount of studies have been performed to evaluate whether specific pore shapes have an influence on cell activity and tissue(More)
The aim was to develop a hybrid three-dimensional-tissue engineering construct for chondrogenesis. The hypothesis was that they support chondrogenesis. A biodegradable, highly porous polycaprolactone-grate was produced by solid freeform fabrication. The polycaprolactone support was coated with a chitosan/polyethylene oxide nanofibre sheet produced by(More)
37 patients with atherosclerosis of lower extremities and the mean claudication distance of 300-500 m (Fontaine 11 degrees) were subjected to pharmacotherapy with pentoxyfilline 600 mg twice daily, and walking exercise tests on a treadmill. The concentrations of ATP and magnesium ions in erythrocytes were assessed in the patients in resting condition, and(More)
Small fractures in bone tissue can heal by themselves, but in case of larger defects current therapies are not completely successful due to several drawbacks. A possible strategy relies on the combination of additive manufactured polymeric scaffolds and human mesenchymal stromal cells (hMSCs). The architecture of bone tissue is characterized by a structural(More)
This paper is concerned with reliable and physically sound elasticity determination of rapid-prototyped tissue engineering scaffolds made of poly-L-lactide (PLLA), with and without small portions of tricalcium phosphate (TCP) inclusions. At the level of overall scaffolds, that is, that of several millimeters, multiple uniaxial loading-unloading(More)
The capacity of bone grafts to repair critical size defects can be greatly enhanced by the delivery of mesenchymal stem cells (MSCs). Adipose tissue is considered the most effective source of MSCs (ADSCs); however, the efficiency of bone regeneration using undifferentiated ADSCs is low. Therefore, this study proposes scaffolds based on polycaprolactone(More)
Aims Nowadays medicine needs material to heal, unite and complete defects of the affected tissue. It often involves with creating three dimensional constructs. Biodegradable materials, which are currently available for bone tissue regeneration, still have limitations regarding their degradation rate. In this case there is a growing need for novel(More)
