background tissue engineering is used for the treatment of many diseases, and the ideal cell source for cartilage tissue engineering is chondrocytes. the main limitation of chondrocyte is the low number of cells in cartilage tissue engineering. this study investigated a suitable cell source with high proliferation rate to obtain a large number of chondrocytes. methods adult cartilage tissue sam...
spinal cord injury (sci)-induced systemic inflammatory response affects multiple organs outside the spinal cord. treatment options for such complications are lacking. valproic acid (vpa) is a histone deacetylase inhibitor, acting directly at the level of gene transcription by inhibiting histone deacetylation and making transcription sites more accessible. acetylation of histones is critical to...
Stem cell research has obtained much prominence in recent years for its therapeutic potential in dealing with serious diseases, many of which are essentially incurable by routine therapies. Mesenchymal stem cells with pluripotency and immunomodulatory properties are suitable candidates for tissue engineering and regenerative medicine. Today, nanofibrous scaffolds are widely used in tissue en...
currently autografts are gold standards for craniomaxillofacial bone regeneration. but autografts have some limitations. bone tissue engineering has been introduced to overcome these limitations. it consist three components: stem cells, growth factor, and scaffold. scaffold provides an environment for bone growth and simplifies cell adhesion, differentiation and proliferation. in this review, a...
in this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. the polymers were characterized by nuclear magnetic resonance (nmr) spectrometry, fourier transform infrared spectroscopy (f...
tissue engineering based on the adipose derived stem cells promote a strong strategy to propagation of bone, cartilage and fat tissues in the three-dimensional scaffolds, fabricated by combining biological materials with suitable and appropriate growth factors. in this study, a peo scaffold was used to show that mesenchymal stem cells can attach well; the aim of this study was the investigati...
in this investigation, hydroxyapatite (hap) nanostructure with uniform morphologies, controllable size, nano-dispersion and narrow-size distribution in diameter has been synthesized successfully by low-temperature hydrothermal process, and the as-synthesized powders were characterized by energy-dispersive x-ray spectroscopy, scanning electron microscopy, high-resolution transmission electron mi...
hyaline cartilage is a vascular and neural tissue with scanty chondrocytes and limited regenerative ability. after some serious injuries of the cartilage, healing process will take place through the formation of fibrocartilage structures. currently, tissue engineering and cell therapy are 2 interesting therapeutic fields dealing with regenerative medicine. in this regard, tissue regeneration ha...
articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. the scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. cartilage tissue engineering requires 3 components: cells, scaffold, and environment. owning to their ...
tissue engineering is based on three main factors including scaffolds, cells and growth factors. natural scaffolds derived from decellularized tissues and organs have been successfully used in tissue engineering. decellularization studies have shown that natural scaffolds which maintaine their main structure and properties could be a suitable tool for studying cellular behaviors and preparation...
