Directed Differentiation of Primitive and Definitive Hematopoietic Progenitors from Human Pluripotent Stem Cells

The overall goal of this method is to direct the Differentiation of Human Pluripotent Stem Cells toward the Primitive or Definitive Hematopoietic Program using a stage specific signal manipulation approach. This method can address many key questions in the field, such as understanding the signal and transcriptional regulators of human definitive hematopoiesis. The main advantage of this technique is that it uses stage specific manipulation instantly.

Demonstrating this procedure is Carissa Dege, a post doc in my laboratory. To begin the protocol, obtain previously prepared Human Pluripotent Stem Cell Lines or HPSCs grown on mouse embryonic fiberblasts or MEFs to 70%to 80%confluency in a 37-degree Celsius incubator with five percent CO2. Aspirate the HPSC media and add one milliliter of 37-degree Celsius 0.25%Trypsin EDTA to each well for one minute.
