Labs, Surgery, Medicine, Memorial Sloan-Kettering Cancer Center, New York, NY, USA ABSTRACT We present, for the first time, separation of three different prostate cancer cell lines from leukocyte fractions by means of continuous flow acoustophoresis.

16 Osmotically induced cell death reduces the cell size and when mixed with larger, viable cells, the authors successfully concentrated the viable cells based on Cancer cells display acoustic properties enabling acoustophoretic separation from white blood cells (WBCs) with 2–3 log suppression of the WBC background. However, a subset of WBCs has overlapping acoustic properties with cancer cells, which is why label-free acoustophoretic cancer cell isolation needs additional purification prior to analysis. Microfluidic, Label-Free Enrichment of Prostate Cancer Cells in Blood Based on Acoustophoresis | Analytical Chemistry Circulating tumor cells (CTC) are shed in peripheral blood at advanced metastatic stages of solid cancers. Surface-marker-based detection of CTC predicts recurrence and survival in colorectal, breast, and prostate cancer. Acoustophoresis is a non-contact and label-free mode of manipulating particles and cell populations and allows for implementation of several separation modes [ 2 ].

”Miniaturised and Quantitative Techniques Targeting Prostate Cancer” “On microchannel acoustophoresis – Experimental considerations and life science

Materials and Methods Ethics Statement 2013-05-27 · Here, we demonstrate that acoustophoresis affects neither the responsiveness nor the endogenous PSA secretion or PSA secretion induced by R1881 (a synthetic androgen), in prostate cancer cells. Acoustophoresis may therefore be a suitable technique for live CTC isolation from blood. Microchannel acoustophoresis has been evaluated for isolation of prostate and breast cancer cells from blood. Cancer cells are discriminated primarily based on their higher acoustophoretic mobility as compared to the white blood cells (WBCs).

Acoustophoresis-based microfluidic devices are currently being explored as a mean to enrich and discriminate viable from non-viable tumor cells in peripheral blood . Therefore, we initiated a detailed characterization of the viability and secretory function of tumor cells subsequent to subjecting them to acoustophoretic processing. By increasing the acoustic intensity a recovery of 94.8 ± 2.8% of cancer cells was achieved with 2.2 ± 0.6% contamination of white blood cells.
