Iron overload affects the cell cycle of various cell types, but the effect of iron overload on human pluripotent stem cells (hPSCs) has not yet been reported. Here, we show that the proliferation capacities of human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs) were significantly inhibited by ferric ammonium citrate (FAC) in a concentration-dependent manner. Additionally, deferoxamine (DFO) protected hESCs/hiPSCs against FAC-induced cell cycle arrest. However, iron overload did not affect pluripotency in hESCs/hiPSCs. Further, treatment of hiPSCs with FAC resulted in excess reactive oxygen species production and DNA damage. Collectively, our findings provide new insights into the role of iron homeostasis in the maintenance of self-renewal in hPSCs.

The effects of ascorbate on adult cell fate specification remain largely unknown. Using our stepwise and chemically defined system to derive lateral mesoderm progenitors from human pluripotent stem ce...
Pluripotent stem cells (PSCs) such as embryonic stem cells (ESCs), ESCs derived by somatic cell nuclear transfer (ntESCs), and induced pluripotent stem cells (iPSCs) have unlimited capacity for self-r...
Does the X chromosome inactivation (XCI) of Klinefelter syndrome (KS)-derived human induced pluripotent stem cells (hiPSCs) correspond to female human pluripotent stem cells (hPSCs) and reflect the KS...
We generated three human induced pluripotent stem cell (hiPSC) sublines from human dermal fibroblasts (HDFs) (MZT04) generated from a skin biopsy donated from a previously fertile woman. The skin biop...
Assessment of iron content in the liver is crucial for diagnosis/treatment of iron-overload diseases. Nonetheless, T*-based methods become challenging when fat and iron are simultaneously present. Thi...
The goal of this study is to examine the impact of iron overload in patients undergoing a bone marrow transplant. We believe that the iron status in these patients is associated with comp...

Recent retrospective studies have suggested that iron overload is a clinically important problem in patients undergoing ablative stem cell transplantation. However, these studies relied o...
Dysmetabolic iron overload syndrome and genetic hemochromatosis are frequent causes of iron overload. Polyphenols are efficient iron-chelators. Investigator hypothesize that polyphenol sup...

A type of PLURIPOTENT STEM CELLS derived from early stage human embryos, up to and including the BLASTOCYST stage.
An excessive accumulation of iron in the body due to a greater than normal absorption of iron from the gastrointestinal tract or from parenteral injection. This may arise from idiopathic hemochromatosis, excessive iron intake, chronic alcoholism, certain types of refractory anemia, or transfusional hemosiderosis. (From Churchill's Illustrated Medical Dictionary, 1989)
The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
Colony-forming cells which give rise to NEOPLASMS. They have properties similar to normal stem cells, i.e., high proliferative and self-renewal capacities.
Cells from adult organisms that have been reprogrammed into a pluripotential state similar to that of EMBRYONIC STEM CELLS.
