spinal cord injury (sci) is one of the devastating conditions leading to functional and neurological deficits following road traffic accidents. to date, there is no definite treatment for repairing damaged spinal cord tissue. in this regard, cell therapy opens a new window in front of scientists by using different cells such as mesenchymal stem cells, olfactory ensheathing cells, schwann cells,...

introduction: esophageal squamous-cell carcinoma (scc) is one of the most common malignancies in iran. to reduce the incidence of esophageal scc, it is important to recognize the controllable risk factors and prevent them. celiac disease is widely known as a possible risk factor for esophageal scc.  thus, we decided to assess the frequency of celiac disease in esophageal scc patients in north e...

the cellular therapy and nerve tissue engineering will probably become a major therapeutic strategy for promoting axonal growth through injured area in central nervous system and peripheral nervous system in the coming years. the stem cell carrier scaffolds in nerve tissue engineering resulted in strong survival of cells and suitable differentiation into neural cells, so this pathway should be ...

Bioceramic scaffolds such as silicate bioceramics have been widely used for bone tissue engineering. However, their high degradation rate, low mechanical strength and surface instability are main challenges compromising their bioactivity and cytocompatibility which further negatively affect the cell growth and attachment. In this study, we have investigated the effects of silk fibroin coating o...

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...

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 t...

objective articular cartilage as an avascular skeletal tissue possesses limited capacity to heal. on the other hand, it is believed that the regeneration capacity of each tissue is largely related to its stem cell contents. little is known about the presence of mesenchymal stem cells in articular cartilage tissue. this subject is investigated in the present study. materials and methods articula...

objective(s): atherosclerosis is an important risk factor for coronary heart disease. neuropeptide y (npy) and its receptors, located in peripheral tissue such as white adipose tissue, have been linked to obesity and fat storage. the role of npy in atherosclerosis has not yet been fully studied, so this study was conducted to further investigate the effect of biie 0246, an npy receptor antagoni...

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. ...
