Abstract: The present description relates to in vitro methods for culturing hematopoietic stem cells (HSCs) under mild hyperthermia conditions (e.g., between 38° C. and 40° C.) in the presence of a pyrimidoindole derivative agonist of hematopoietic stem cell expansion. The combined use of mild hyperthermia and the pyrimidoindole derivative act synergistically to promote expansion of CD34+ HSCs and/or differentiation into progenitor cells (e.g., megakaryocytic progenitors). The present description also relates to in vitro expanded cell populations of HSCs and/or progenitors, as well as uses thereof in therapy (e.g., transplantation).
Abstract: A method is described for predicting incipient diabetes, metabolic disorders or the metabolic syndrome by developing a personal temporal Phosphatase profile, which is generated by measuring phosphatase concentration in stool at a single time-point or multiple time-points.

Abstract: This disclosure provides methods of making a megakaryocyte-erythroid progenitor cell (MEP), comprising differentiating a stem cell into a MEP in culture in the presence of an aryl hydrocarbon receptor (AhR) agonist. In some embodiments the stem cell is a pluripotent stem cell. In some embodiments the MEP co-expresses CD41 and CD235. In some embodiments the number of MEPs produced in the culture increases exponentially. Methods of making a red blood cell (RBC) by culturing a MEP in the presence of an AhR agonist are also provided. Methods of making a megakaryocyte and/or a platelet, comprising culturing a MEP in the presence of an AhR modulator are also provided. In some embodiments the AhR modulator is an AhR antagonist. This disclosure also provides compositions comprising at least 1 million MEPs per ml and compositions in which at least 50% of the cells are MEPs.

Abstract: An adjuvant for rapid proliferation of human mesenchymal stem cells in vitro is provided to overcome the problem of low cell amplification efficiency of human mesenchymal stem cells in a culture process. The adjuvant added for the culture of human mesenchymal stem cells includes at least one antioxidant, and a basic fibroblast growth factor (FGF-2). The adjuvant is added into a medium containing the human mesenchymal stem cells, and the culture takes place in a normal oxygen environment (21% oxygen tension), and the cells are divided rapidly, and the cell cycle at synthesis phase (S phase) percentage is increased to reduce ageing and improve differentiation potential. The adjuvant not only amplifies human mesenchymal stem cells rapidly to harvest the growth factor, but also maintains the characteristics of the multifunction of stem cells for the purposes of culturing and amplifying the human mesenchymal stem cells.
