The National Cancer Institute (NCI) awarded a Project Grant (CFDA 93.395 - Cancer Treatment Research) totaling $180,632.00 to the University of Pittsburgh to study methods for inhibiting breast cancer metastasis. The key objectives of this initiative are to:

  1. Discover and validate compounds that can effectively block the engulfment of mesenchymal stem cells (MSCs) by breast cancer cells, as this engulfment process has been linked to increased tumor aggressiveness and metastatic potential. The researchers will use a high-throughput microfluidic cell pairing platform to screen a library of 2,726 compounds with established safety profiles and validate promising candidates in 3D cancer spheroid models and animal studies.

  2. Unravel the mechanistic role of cancer-MSC engulfment in driving metastasis, including determining if the engulfing cancer cells represent a distinct sub-population and identifying the key genetic factors involved in the engulfment process through CRISPR screening. The researchers will validate the impact of identified genes on inhibiting engulfment in vitro and metastasis in vivo.

This multifaceted project aims to develop new therapeutic approaches by repurposing FDA-approved drugs to block the critical cancer-MSC engulfment process, which could have broad applicability for addressing metastasis across various malignancies. The award period runs from May 1, 2025 through April 30, 2027.
