The feasibility of isolating and manipulating mesenchymal stem cells (MSCs) from human patients provides hope for curing numerous disease and disorders. Recent phenotypic analysis showed heterogeneity of MSCs. A nestin progenitor cell is a subpopulation within MSCs which plays a role in pancreas regeneration during embryogenesis. This study aimed to separate nestin (+) cells from human bone mar...

The potential for human disease treatment using human pluripotent stem cells, including embryonic stem cells and induced pluripotent stem cells (iPSCs), also carries the risk of added genomic instability. Genomic instability is most often linked to DNA repair deficiencies, which indicates that screening/characterization of possible repair deficiencies in pluripotent human stem cells should be a...

Pigs have great potential to provide preclinical models for human disease in translational research because of their similarities with humans. In this regard, porcine pluripotent cells, which are able to differentiate into cells of all three primary germ layers, might be a suitable animal model for further development of regenerative medicine. Here, we describe the current state of knowledge on...

INTRODUCTION Embryonic stem cells and induced pluripotent stem cells have emerged as the gold standard of pluripotent stem cells and the class of stem cell with the highest potential for contribution to regenerative and therapeutic application; however, their translational use is often impeded by teratoma formation, commonly associated with pluripotency. We discuss a population of nontumorigeni...

UNLABELLED The purpose of this study was to determine the functional recovery of the transplanted induced pluripotent stem cells in a rat model of Huntington's disease with use of 18F-FDG microPET/CT imaging. METHODS In a quinolinic acid-induced rat model of striatal degeneration, induced pluripotent stem cells were transplanted into the ipsilateral lateral ventricle ten days after the quinol...

Skin stem cells are very important in cosmetics, pharmacological and regenerative medicine and burn cases. Foreskin samples surgically removed after circumcision from boys below 7 years were collected and primary epidermal cells were prepared by enzymatic and mechanical tituration method. Selecting CD133 (prominin-1) multipotent stem cell marker, enriched stem cells were analyzed by MACS using ...

the aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. blastocyst stage embryos from pregnant nmri mice were obtained and cultured for 1-2 days in dmem medium. the inner cell masses formed...

A mere 9 years have passed since the revolutionary report describing the derivation of induced pluripotent stem cells from human fibroblasts and the first in-patient translational use of cells obtained from these stem cells has already been achieved. From the perspectives of clinicians and researchers alike, the promise of induced pluripotent stem cells is alluring if somewhat beguiling. It is ...

BACKGROUND Ex vivo manufacture of red blood cells from stem cells is a potential means to ensure an adequate and safe supply of blood cell products. Advances in somatic cell reprogramming of human induced pluripotent stem cells have opened the door to generating specific cells for cell therapy. Human induced pluripotent stem cells represent a potentially unlimited source of stem cells for eryth...

UNLABELLED Stem cell therapy has been viewed as a promising therapeutic strategy in ischemic cardiovascular disease for almost a decade. Although many progenitor/stem cells obtained from patients have been investigated, and are alleged to be suitable for autologous transplantation, their therapeutic application has been limited by their inability to yield a sufficient number of stem cells, as w...
