Using quantitative PCR, we demonstrate how the well-established chick CAM model can be used to quantitatively analyze the metastasis of human tumor cells to distant organs.

Circulating tumor cells (CTCs) are prognostic in several metastatic cancers. This manuscript describes the gold standard CellSearch system (CSS) CTC enumeration platform and highlights common misclassification errors. In addition, two adapted protocols are described for user-defined marker characterization of CTCs and CTC enumeration in preclinical mouse models of metastasis using this technology.

Generation of Organ-conditioned Media and Applications for Studying Organ-specific Influences on Breast Cancer Metastatic Behavior

Matthew M. Piaseczny^*1,2, Graciella M. Pio^*1,2, Jenny E. Chu^1,2, Ying Xia¹, Kim Nguyen^1,3, David Goodale¹, Alison Allan^1,2,4,5

This manuscript describes an ex vivo model system comprised of organ-conditioned media derived from the lymph node, bone, lung, and brain of mice. This model system can be used to identify and study organ-derived soluble factors and their effects on the organ tropism and metastatic behavior of cancer cells.

Isolation and Functional Assessment of Human Breast Cancer Stem Cells from Cell and Tissue Samples

Vasudeva Bhat^1,2, Cory Lefebvre^1,2, David Goodale¹, Mauricio Rodriguez-Torres^1,2, Alison L. Allan^1,2,3,4

¹London Regional Cancer Program, ²Department of Anatomy & Cell Biology, Western University, ³Department of Oncology, Western University, ⁴Lawson Health Research Institute

This experimental protocol describes the isolation of BCSCs from breast cancer cell and tissue samples as well as the in vitro and in vivo assays that can be used to assess BCSC phenotype and function.
