This image shows H1 human embryonic stem cells (hESCs) expressing green fluorescent protein. Undifferentiated stem cells such as these provide the starting point for much of our research.
A hESC-derived megakaryocyte with positive staining for von Willebrand Factor (red), CD41 (green), and DAPI (blue) is shown. Mature megakaryocytes such as this one are responsible for producing blood platelets.
This Giemsa-stained peripheral blood smear shows a granulocyte in a sea of red blood cells. Inspired by the life saving component of red blood cells, we focus on using hES and iPS cells as a resource for donorless transfusable blood.
