- Overview
-
Flow cytometry is a technology that can be used to rapidly analyze physical and chemical properties of individual cells. It is a powerful tool with many applications in multiple disciplines such as blood cancers, immunology, molecular biology, and cellular therapy. For example, it is very effective for the study of the immune system and its response to infectious diseases and cancer.

Minimal Residual Disease & Leukemic Stem Cells
Minimal residual disease refers to a small number of malignant cells that remain in the patient during or after treatment when the patient has no signs or symptoms of the disease. Flow cytometry allows for MRD analysis by looking at different expression of cellular antigens on malignant cells compared to normal cells. As part of Dr. Suzanne Vercauteren’s team, our lab has implemented 10-color flow cytometry panels for MRD detection in B-cell acute lymphoblastic leukemia (the most common type of blood cancer in children) post chemotherapy and post CD19 directed therapy. In collaboration with the BRAVe initiative, we are currently looking at more markers to identify leukemic stem cell populations, which may contribute to relapse or treatment resistance.Primary Immunodeficiency Disorders and Hemophagocytic Lymphohistiocytosis
PIDDs are a heterogeneous group of inherited disorders resulting from genetic defects that impair the immune system. Given the complexity of the immune system, the clinical manifestations of PIDDs are highly variable and may present with recurrent infections, autoimmunity and predisposition to cancer. Under the “Diseases of Immune Dysregulation” group of PIDD is a life threatening disorder called Hemophagocytic Lymphohistiocytosis (HLH), leading to an overactive, dysfunctional response of immune system, low blood cell counts and multi-organ damage. Our lab implemented clinical flow cytometry panels to support newborn screening for severe combined immunodeficiency (SCID) and expand the investigation for PIDD, as well as Perforin assay for screening of primary HLH. We continue to optimize our assay methodologies and reference ranges to support the diagnosis of PIDD in BC.Cellular Therapy
Our lab is validating several flow cytometry panels for product assessment of several graft engineering projects under TRACE initiative, including T-cell alpha/beta depleted stem cell transplantation to reduce GvHD risk, as well as viral specific T-cell therapy for severe protracted viral infection post-transplant.Research Group MembersMichelle Dittrick, Clinical Research Program Manager
A safer treatment path for high-risk children to overcome food allergies
New research from BC Children’s Hospital Research Institute and UBC reveals a safe path to overcoming food allergies for older children or building resistance for those who can’t risk consuming allergens. It’s called sublingual immunotherapy (SLIT), and it involves placing small amounts of food allergens under the tongue.
