Summary

Cancer stem cells (CSC) are rare, inherently chemoresistant cells, which have the capacity to differentiate and generate the numerous cancer cell types observed in a tumor. CSC are hypothesized to be the primary source of cancer recurrence and ultimately a patient's demise. The primary objective of my laboratory is to understand cellular interactions in the tumor vascular/cancer stem cell niche with the goal of developing novel therapeutics targeting CSC proliferation and differentiation. In order to characterize these interactions, we have performed an extensive characterization of ovarian CSC and have begun to define a differentiation hierarchy of the ovarian CSC. In addition, we have characterized several components of the ovarian CSC niche; we have extensively characterized the ovarian tumor vasculature, tumor vascular associated leukocytes, and cancer associated mesenchymal stem cells. We have developed novel in vitro microfluidics devices as a means to study symmetric versus asymmetric divisions of CSC, and novel human in vivo tumor models for the study of ovarian CSC growth and differentiation. Finally, we have developed tumor vascular niche targeted nanoparticle platform with which to assess the efficacy of CSC targeted therapies delivered specifically to CSC. We are now perfectly placed to significantly develop the field of cancer stem cell based differentiation targeted therapies.
