in spite of sonic pessimistic attitudes towards methodology of economics, it has succeeded as a central theme in numerous books, refereed journals, international conferences and symposiums whose volume is increasing at an unprecedented rate. the proliferation of methodological literature also is accompanied by a proliferation of issues that concern: the goals of economics, realism of economics,...

It is now well established that the type la of serine/threonine protein phosphatases (PP1α) may be implicated in malignant phenotype. Although the PP1α mRNA level increased in livers at preneo-plastic stages of hepatocarinogenesis and all of examined rat ascites hepatomas, unexpectedly, dra-matically decreased in some of primary hepatomas. In order to elucidate the low level of PP1α mRNA in som...

Introduction: The native inability of nervous system to regenerate, encourage researchers to consider neural tissue engineering as a potential treatment for spinal cord injuries. Considering the suitable characteristics of induced pluripotent stem cells (iPSCs) for tissue regeneration applications, in this study we investigated the adhesion, viability and proliferation of neural progenitors (de...

Neural stem cells are undifferentiated cells that are located in limited areas of central nervous system. These cells have proliferation and self-renew ability and can be differentiated into neurons and glial cells. Mature nerve cells do not have proliferative ability; and due to the limited number of nerve stem cells, injuries to the nervous system are not recoverable. The purpose of this revi...

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...
