Researchers identify novel approach to create red blood cells, platelets in vitro
Date:5/30/2013

(Boston) A study led by Boston University School of Medicine has identified a novel approach to create an unlimited number of human red blood cells and platelets in vitro. In collaboration with Boston University School of Public Health (BUSPH) and Boston Medical Center (BMC), the researchers differentiated induced pluripotent stem (iPS) cells into these cell types, which are typically obtained through blood donations. This finding could potentially reduce the need for blood donations to treat patients requiring blood transfusions and could help researchers examine novel therapeutic targets to treat a variety of diseases, including sickle cell disease.

Published online in the journal Blood, the study was led by George J. Murphy, PhD, assistant professor of medicine at BUSM and co-director of the Center for Regenerative Medicine (CReM) at Boston University and BMC and performed in collaboration with David Sherr, PhD, a professor in environmental health at BUSM and BUSPH.

iPS cells are derived by reprogramming adult cells into a primitive stem cell state that are capable of differentiating into different types of cells. iPS cells can be generated from mature somatic cells, such as skin or blood cells, allowing for the development of patient-specific cells and tissues that should not elicit inappropriate immune responses, making them a powerful tool for biological research and a resource for regenerative medicine.

In this study, the iPS cells were obtained from the CReM iPS Cell Bank. The cells were exposed to growth factors in order to coax them to differentiate into red blood cells and platelets using a patented technology. These stem cells were examined in depth to study how blood cells form in order to further the understanding of how this process is regulated in the body.

In their new approach, the team added compounds that modulate the aryl hydrocarbon receptor (AhR) pathway. Previous research has shown th
