Human multiple myeloma (MM) cells require the supportive microenvironment of mesenchymal cells and extracellular matrix components for survival and proliferation. We established an in vivo chicken embryo model with engrafted human myeloma and mesenchymal cells to study effects of cancer drugs on tumor growth, invasion and angiogenesis.

Methods allowing the characterization and isolation of stem cell populations from biological samples are critical for the advance of stem cell-targeted treatments in cancer and beyond. Here, we provide a detailed protocol for cancer stem cell isolation using the dye-triggered side population phenotype.

Quantification of donor-derived cells is required to monitor engraftment after stem cell transplantation in patients with hemoglobinopathies. A combination of flow cytometry-based cell sorting, colony formation assay, and subsequent analysis of short tandem repeats may be used to assess the proliferation and differentiation of progenitors in the erythroid compartment.
