Nanofibrous scaffolds are artificial extracellular matrices which provide natural environment for tissue formation. In comparison to other forms of scaffolds, the nanofibrous scaffolds promote cell adhesion, proliferation and differentiation more efficiently due to having high surface to volume ratio. Although scaffolds for tissue engineering have been fabricated by various techniques but elect...

In this study, we have developed a combined approach to accelerate the proliferation of mesenchymal stem cells (MSCs) in vitro, using a new nanofibrous scaffold made by needleless electrospinning from a mixture of poly-ε-caprolactone and magnetic particles. The biological characteristics of porcine MSCs were investigated while cultured in vitro on composite scaffold enriched with magnetic nanop...

Over the last 10 years great research interest has been directed toward nanofibrous architectures produced by electrospinning bioactive plant extracts. The resulting structures possess antimicrobial, anti-inflammatory, and anti-oxidant activity, which are attractive for biomedical applications and food industry. This review describes the diverse approaches that have been developed to produce el...

The fracture of bones and large bone defects owing to various traumas or natural ageing is a typical type of tissue malfunction. Surgical treatment frequently requires implantation of a temporary or permanent prosthesis, which is still a challenge for orthopaedic surgeons, especially in the case of large bone defects. Mimicking nanotopography of natural extracellular matrix (ECM) is advantageou...

Poly-L-lactic acid (PLLA) nanofibrous membranes are widely utilized for tissue regeneration. Low intensity pulsed ultrasound (LIPUS) has been considered as a feasible modality for bone union. The aim of the present study was to investigate the potential synergistic effect of LIPUS and PLLA electrospun nanofibrous membranes on large cortical bone defects in rabbits in vivo. The bilateral rabbit ...

Poly lactic acid (PLA) was electrospun with various concentrations of multi-wall carbon nanotubes (MWNT) and thermal bonding was utilized as a post-processing treatment to improve the mechanical and electrical properties of the nanofibrous mats. Thermally bonded fiberefiber junctions were observed with scanning electron microscopy. An increase in either the strength or modulus of the PLA mats b...
