skeletal muscle is a highly differentiated tissue with very specific functions which has low potential of regeneration. skeletal muscle injuries especially in athletes almost have lead to muscular dysfunctions and healing may be prolonged for several years. therefore, working on skeletal muscle differentiation remained an importance in biomedical researches. adipose derived stem cells (adscs) a...
background: bone marrow-derived mesenchymal cellscan transdifferentiate into cardiomyocyte cells and improveheart function after transplantation. since biomaterials canimprove the cell retention in the site, cell survival and differentiation,heart tissue engineering is now being explored as anapplied solution to support cell-based therapies and increasetheir efficacy for myocardial diseases. ch...
Modeling, design and fabrication of tissue scaffolds with intricate architecture, porosity and pore size for desired tissue properties presents a challenge in tissue engineering. This paper will present the details of our development in the design and fabrication of the interior architecture of scaffolds using a novel design approach. The interior architecture design (IAD) approach seeks to gen...
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. ...
Background and purpose: Natural bone is a combination of polymer and biological apatite, therefore, the composite scaffolds made of polymers and bioactive ceramics have found wide applications in bone tissue engineering studies. Among various polymers, the poly-L-lactic acid (PLLA) and hydroxyapatite (HA) have attracted much attention due to their optimal properties. In this study, using PLLA p...
Objective (s): The scarcity of articular cartilage defect to repair due to absence of blood vessels and tissue engineering is one of the promising approaches for cartilage regeneration. The objective of this study was to prepare an extracellular matrix derived decellularized bovine articular cartilage scaffold and investigate its interactions with seeded rat bone marrow mesenchymal stem cells (...
Abstract Background: The amniotic membrane has gained much attention in regenerative medicine as a precious cell source. Recently, reparation of three dimensional matrices (scaffold) with appropriate specificity for cell culture, which depends on cell type, has been the subject of many studies .This study aimed to design optimal three-dimensional matrices in order to utilize amniotic epithel...
