Academic Title: Associate Professor, Department of Pediatrics, University of Washington School of Medicine

"My philosophy in caring for children is to educate the entire family, not just the patient, with respect to their disease and treatment options. In doing so, it is my goal to provide not only information, but a source of support, such that the family and patient, with guidance, feel better able to make health-care decisions. Additionally, I feel it is important to remember that every patient is unique, and I strive to maintain and improve the patient’s quality of life in any treatment decisions made."

  • Colleen Delaney, MD, MSc, is an attending physician at Seattle Children's Hospital; director of the Cord Blood Tranplant Program and associate professor in the Clinical Research Division at Fred Hutchinson Cancer Center; and associate professor at the University of Washington School of Medicine. 

    Dr. Delaney's research interests include hematopoietic stem cell regulation and the development of novel and clinically feasible ex vivo expansion systems for hematopoietic progenitor cells using the Notch ligand, Delta1, which is a known regulator of cell fate determination. Her goal is to improve the outcome of patients in need of a cord blood transplant. Delaney's research on the role of Notch signaling in hematopoietic stem cell regulation has resulted in the development of a pilot study investigating the use of ex vivo expanded cord blood progenitors to augment conventional cord blood transplantation. She is lead investigator in this trial, which began accrual in summer 2006. Delaney is principal investigator on four additional Fred Hutchinson clinical trials investigating the use of single or double unrelated donor umbilical cord blood grafts as an alternative source of stem cells for hematopoietic cell transplant, including a multicenter protocol investigating the use of single versus double unrelated donor umbilical cord blood grafts as the source of stem cells for hematopoietic cell transplantation.
