Dr. Cher is a surgeon-scientist who cares for patients with urologic malignancies. He specializes in all operative procedures for urologic malignancies including robotic and laparoscopic surgery, major tumor resections, continent urinary diversions, and minimally invasive image-guided procedures such as brachytherapy and cryotherapy. Dr. Cher runs a NIH-funded research laboratory devoted to the study of prostate cancer bone metastasis biology using animal models, tissues, and cells. The focus is on proteases, chemokines, and growth factors.

Research Interests

Prostate cancer, bone metastasis, SCID-Hu and exnograft model, bone marrow, and tumor/stromal interaction


Dr. Cher’s laboratory has established a well-funded active basic science research program in the biology of prostate cancer metastasis. The major focus of Dr. Cher’s group is to determine the biological factors responsible for prostate cancer metastasis to bone marrow. This is a highly important and clinically relevant issue because the bone marrow is the most common location for distant spread of prostate cancer. Dr. Cher’s group developed a new experimental model called "SCID-human model of human prostate cancer metastasis to human bone." This animal model offers a number of unique advantages for investigating many of the biological factors involved in human prostate cancer cells interacting with the human bone microenvironment. In collaboration with other researchers at Wayne State University School of Medicine and The Barbara Ann Karmanos Cancer Institute, the Cher laboratory has published over 30 papers in this area of research. Many of these findings have become the basis for clinical trials in patients.
