Bio
Dr. Osborn is an Assistant Professor in the Department of Pediatrics, Division of Blood and Marrow Transplantation. He is also a member of the Cancer Center. Dr. Osborn received his PhD degree from the University of Minnesota in 2009 in the laboratory of Dr. Bruce R. Blazar, MD.
Research Summary
Dr. Osborn's current research is focused on gene and cellular therapy for disorders treated by hematopoietic cell transplantation including: Fanconi anemia, epidermolysis bullosa, and Hurler syndrome. This involves utilizing a patient's own cells for precision gene targeting and correction of their disease causing mutation. Genome editing nucleases and multiple terminally differentiated and stem cell populations are utilized towards optimizing ex vivo cellular therapies.
Gene Therapy
- Non-viral gene transfer for the treatment of inborn errors of metabolism.
Genome Editing
- Correction of disease specific mutations in a precise manner using homologous recombination.
Cellular Therapy
- Ex vivo correction of murine and human adult stem cells.

Jakub Tolar, MD, PhD is the dean of the University of Minnesota Medical School and a Distinguished McKnight University Professor in the Department of Pediatrics, Blood and Marrow Transplant & Cellular Therapy. He is also the vice president for Clinical Affairs at the University of Minnesota, board chair for University of Minnesota Physicians and co-leader of M Health Fairview, the joint clinical enterprise among the University of Minnesota Medical School, University of Minnesota Physicians and Fairview Health Services. An internationally recognized physician and researcher, Dr. Tolar is known for his care of patients with recessive dystrophic epidermolysis bullosa. His research is focused on developing cellular therapies for rare genetic disorders. Originally from the Czech Republic, Dr. Tolar received his medical education (MD) in Prague at Charles University. In 1992, he came to the University of Minnesota, where he received his PhD in Molecular, Cellular & Developmental Biology and Genetics.
Research Summary
Dr. Tolar's research focuses on finding new ways to treat children with lethal, inherited diseases. He is also looking for safer and more effective gene therapy for diseases such as epidermolysis bullosa, mucopolysaccharidosis type I (Hurler syndrome), Fanconi anemia, and dyskeratosis congenita. Additional research interests include reducing the negative effects of stem cell transplantation (such as using mesenchymal stromal cells for graft-versus-host disease); creation and use of induced pluripotent stem cells; gene therapy using gene addition (with viral vectors and trasposons); and gene editing (with synthetic nucleases to repair genes).

John E. Wagner, MD, is a Professor in the Department of Pediatrics, Division of Blood and Marrow Transplant & Cellular Therapy. He is the Founding Director of the new Institute of Cell, Gene and Immunotherapeutics at the University of Minnesota. Co-Director of the Center for Translational Medicine, and holds two endowed chairs—Children's Cancer Research Fund/Hageboeck Family Chair in Childhood Cancer Research, and the University of Minnesota McKnight-Presidential Chair.
Dr. Wagner's research is focused on the development of novel cell therapies for treatment of life threatening diseases. Examples include the development of regulatory T cells that could be used in the treatment of autoimmunity, organ graft rejection as well as graft-versus-host disease, thymic progenitors to repair damaged immune systems, cardiac myoblasts to reverse heart failure, skeletal myoblasts to repair or replace dystrophic muscle fibers in muscular dystrophy, and expansion of the blood-forming stem cell to speed blood and marrow recovery after high doses of chemotherapy and radiation. Dr. Wagner is best known for his pioneering work on the use of placental/cord blood as a source of stem cells for transplantation – a procedure that has now been performed in more than 50,000 patients worldwide.
Research Summary
Dr. Wagner's research has focused on the development of new treatment approaches for life-threatening diseases for which conventional treatments are unsatisfactory. Dr. Wagner is recognized for pioneering the use of double umbilical cord blood transplantation in adults and embryo selection to insure an HLA matched, healthy child ('savior sibling') for another child in need of transplant. He is also a leader in the use of regulatory T cells to prevent rejection and graft versus host disease, expanded blood forming stem cells to speed blood and marrow recovery, novel conditioning regimens to dramatically increase the chance of cure of patients with Fanconi anemia and bone marrow derived stem cells to repair the skin in severely affected children with Epidermolysis Bullosa.

Dr. Michael Zaiken is an Assistant Professor in the Department of Pediatrics, Division of Pediatric Blood and Marrow Transplantation & Cellular Therapy. Dr. Zaiken completed his graduate training at the University of Minnesota in the Molecular, Cellular, Developmental Biology, and Genetics program under the advisement of Dr. Bruce R. Blazar in 2020. He continued on in the laboratory of Dr. Blazar for post-doctoral training focusing on bioinformatics and joined the Department of Pediatrics as faculty in 2023.
Research Summary
Dr. Zaiken’s current research is focused on the application of novel bioinformatic analyses to the treatment of graft vs host disease (GVHD). This primarily focuses on the development of analytics pipelines for deciphering complex ‘omics’ datasets, with an emphasis on single-cell RNA sequencing and spatialomics data. Dr. Zaiken’s long term goal is to use these novel tools to improve understanding of transcriptional regulatory control of immune-malignancies including GVHD, as well as leveraging bioinformatics tools to improve the development of advanced cellular therapies.
