Thorsten Schlaeger, PhD
Head, Human Embryonic Stem Cell Core
Instructor, Harvard Medical School

Thorsten M. Schlaeger, Ph.D., is the head of the Human Embryonic Stem Cell Core Facility of the Stem Cell Program at Boston Children’s Hospital. He studied Human Biology (Humanbiologie) at the University of Marburg and performed his Ph.D. thesis work in the laboratories of Werner Risau and Tom Sato. In 1999 he was awarded the Otto Hahn Medal of the Max Planck Society for his Ph.D. thesis on endothelial cell specific gene expression. Following his postdoctoral research in the laboratory of Stuart Orkin and a short foray into industry, he re-joined Boston Children’s Hospital where he works with Leonard I. Zon and George Q. Daley to develop induced pluripotent stem cell based transfusion and transplantation products. His laboratory focuses on human pluripotent stem cell biology, genome editing, reprogramming, laboratory automationchemical genetics, and imaging technologies.

  • Quality control

    The production ofinduced pluripotent stem cells (iPS cells) is often imprecise, yielding many incompletely reprogrammed cells. Thorsten Schlaeger, PhD, of Children’s Stem Cell Program has developed a battery of tests to ensure that he has the real thing: pure pluripotent stem cells. Schlaeger’s work creates a standard of analysis in the field. Read more and click here to see image.
