the provision of an adequate quantity of cells with proper function and purity is one of the main challenges of tissue engineering studies. stem cells, with their self-renewal and differentiation capacity, are considered one of the main cell sources in the field of tissue engineering. previously, the use of chemical factors seemed to be the only possible way for stem cell differentiation. howev...

objective(s): throughout evolution, mammalians have increasingly lost their ability to regenerate structures however rabbits are exceptional since they develop a blastema in their ear wound for regeneration purposes. blastema consists of a group of undifferentiated cells capable of dividing and differentiating into the ear tissue. the objective of the present study is to isolate, culture expand...

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&...

Human adipose tissue represents an abundant, practical and appealing source of donor tissue for autologous cell replacement. Recent findings have shown that stem cells within the stromalvascular fraction of adipose tissue display a multilineage developmental potential. Adipose tissue-derived stem cells can be differentiated towards adipogenic, osteogenic, chondrogenic,myogenic and neurogenic li...

Nanofiber scaffolds and bio-ceramic nanoparticles have been widely used in bone tissue engineering. The use of human induced pluripotent stem cells (hiPSCs) on this scaffold can be considered as a new approach in the differentiation of bone tissue. In the present study, a polyaniline-gelatin-polycaprolactone (PANi-GEL-PCL) composite nanoscaffold was made by electrospinning and modified superfic...

introduction: failure of human body tissue and organs is believed to be one of the most important health problems all over the world. the great challenge for tissue engineers is to optimize suitable systems to separate, proliferate and differentiate the cells so that they can set out to create tissue by a harmonic 3-d growth. therefore, the tissue engineers must provide an environment like the ...

Objective(s) Bone marrow is the traditional source of human multipotent mesenchymal stem cells (MSCs), but adipose tissue appears to be an alternative and more readily available source. In this study, rat adipose-derived stem cells (ADSCs) were induced to differentiate into Schwann-like cells and compared with rat bone marrow stem cells (BMSCs) for their Schwann-like cells differentiation pote...
