Developmental & Stem Cell Biology

686 Bay St, Toronto, ON M5G 0A4
Najeeb Siddiqui, Research Program Manager

We're pushing the boundaries of stem cell biology. We're focused on understanding molecular genetic mechanisms affecting embryonic development, organ formation, tissue homeostasis and regeneration.

The Developmental & Stem Cell Biology program is making an impact on paediatric health-care by translating our research into treatments for associated developmental disorders like childhood cancer, birth defects, and other paediatric diseases.

We continue to develop new therapeutic approaches for children and youth through a better grasp of developmental genetics, genomics, and stem cell biology. 

Research team

Program head Dr. Brian Ciruna and the scientists that lead DSCB labs and core facilities are supported by over 225 graduate students, postdoctoral fellows, research associates, technicians, and administrative staff. 

You'll find our lab work regularly published in top peer-reviewed medical and scientific journals. Our scientists and trainees receive consistent funding from the Natural Sciences and Engineering Research Council of Canada (NSERC), Canadian Institutes of Health Research (CIHR), March of Dimes Foundation, Canada Research Chairs, NIH, Genome Canada, Canada Foundation for Innovation, and several other national and international organizations, illustrating the importance and impact of DSCB research.

We always welcome new trainees and staff that are eager to improve the health outcomes of children through cutting-edge biomedical research.

Uncovering the mysteries of relapsed brain tumours

Findings from a large international study on the genomic profile of medulloblastoma at the time of relapse may lay foundation for future clinical trials to develop new therapeutic strategies.

Research themes

Our team works across a number of research themes and labs. See what child health challenges we're tackling at each facility by pushing our understanding of stem cells.

Genetic models of human development and disease

We utilize diverse experimental organisms in their research, including C. elegans, D. melanogaster, zebrafish, planaria, and mice. By developing genetic models of numerous human diseases and cancer, we provide an unmatched platform for interrogating pathogenic mechanisms and performing genetic modifier and therapeutic drug screens.

Mechanisms of tissue patterning and organ development

Developmental signaling pathways – including BMP, Hh, FGF, Notch, TGFb, PCP, and Wnt, – play key roles in pattern formation and organogenesis. We examine the roles of these signaling pathways, as well as other regulatory factors in the development of diverse tissues and organs (e.g. blood, bone, brain, heart, gut, kidney, limb, lung, and skin). 

Molecular regulation of cell fate decision, cell differentiation and cell death

We aim to answer a fundamental question in developmental biology - How do cells adopt their fate? Our team studies molecular switches that regulate a cell's fate, as well as mechanisms that program cells to die. 

Stem cell biology, tissue engineering and regenerative medicine

We study the molecular genetic regulation of stem cell states, including embryonic, induced pluripotent, cancer, and multiple tissue stem cell models. Stem cells offer tremendous potential for repair and/or regeneration of damaged tissues and organs. We unlock how stem cells and organoids can be used in regenerative medicine and tissue engineering, such as spinal cord injury and bladder regeneration.

Developmental and Stem Cell Biology Labs

Core facilities

Centre for Advanced Single Cell Analysis

CASCA provides comprehensive training and expert consultation services to enable researchers to use the Fluidigm Helios Mass Cytometry (CyTOF), Fluidigm Hyperion Imaging Mass Cytometry (IMC) and BD Rhapsody single cell RNA sequencing (scRNA-Seq) platforms.
