Request PDF | Acoustophoresis in Tumor Cell Enrichment | This chapter outlines the opportunities and current developments of label-free separation of circulating tumor cell (CTC) from blood cells

Similar rates of cancer-cell recovery, cancer-cell purity, and fold-enrichment were seen with both prostate cancer (DU145, PC3) and breast cancer (MCF7) cell line cells. We identified eosinophil granulocytes as the predominant white blood cell (WBC) contaminant (85%) in the enriched cancer-cell fraction.

Cancer cells display acoustic properties enabling acoustophoretic separation from white blood cells (WBCs) with 2–3 log suppression of the WBC background. abstract = "Metastatic disease is responsible for most cancer deaths, and hematogenous spread through circulating tumor cells (CTC) is a prerequisite for tumor using high throughput multiplex acoustophoresis, Lab Chip, 2019, 19, cancer cells by means of acoustophoresis, Integrative Biology, 2016, Deierborg, T.; Label-free concentration of viable neurons, hESCs and cancer acoustophoresis chip enabling tumor cell enrichment from white blood cells.

Prostate cancer cell viability is not affected by acoustophoresis. Cell viability was determined after acoustophoresis (0, 10 and 20 V pp), for four prostate cancer cell lines: DU 145 (a), PC3 (b), LNCaP (c) and VCaP (d). Left panels show the percentage of cell death directly after acoustophoresis measured by trypan blue exclusion. acoustophoresis (acoustic manipulation) while the passive method is based on inertial microfluidics (hydrodynamic manipulation). In paper I, acoustic capillary-based cavity resonator was used to study aggregation of silica and polystyrene particles. We found that silica particles show faster aggregation Andreas Josefsson/Stina Rudolfsson, Kirurgi och perioperativa vetenskaper, Umeå universitet, fick 820 000 kronor.

For nonfixed, viable cells, tumor cell recovery ranged from 72.5% to 93.9% with purity ranging from 79.6% to 99.7%. These data contribute proof-in-principle that label-free microfluidic acoustophoresis can be used to enrich both viable and fixed cancer cells from WBCs with very high recovery and purity.

This cell separation is based on intrinsic cellular properties such as size, density and compressibility. The aim of this thesis was to compare different ways of dissociating tissue - specifically breast cancer tissue - and sorting out tumour cells and immune cells from the dissociated tissue using acoustophoresis in a microfluidic chip. Microfluidic, Label-Free Enrichment of Prostate Cancer Cells in Blood Based on Acoustophoresis Forskningsoutput : Tidskriftsbidrag › Artikel i vetenskaplig tidskrift Översikt Using this microchannel configuration, several publications have shown cancer cell lines (breast and prostate) being efficiently separated from WBCs from RBC-lysed blood using acoustophoresis with BASWs [3, 20].This label-free separation occurs because larger-sized cancer cells focus faster to the center pressure node than WBCs in the separation channel; thus, if flow rates are optimized the ACOUSTOPHORESIS -A SOUND APPROACH TO CHIP BASED CELL HANDLING – T. Laurell1,2 1 Dept.

The single inlet approach makes this instrument insensitive to acoustic impedance mismatch; a phenomenon reported to importantly affect accuracy in multi-laminar flow stream acoustophoresis. On the basis of these findings, we anticipated that the separation of cancer cells from blood would be greatly improved with regard to WBCs, compared to previously reported acoustophoresis-based methods of cell separation. 21 A dramatic improvement was indeed seen, yielding tumor cell recoveries of 87 and 83% of fixed tumor cells (DU145 and PC3, respectively) and a corresponding WBC suppression of 99.3%, at a sample-processing rate of 4.2 mL/h using a single acoustophoresis channel.It is Acoustophoresis offers non-contact and label-free cell separation based on size and intrinsic cell properties 14 without being detrimental to cells or altering their phenotype.

Our studies indicate that microchannel acoustophoresis can be tuned for effective cell handling without having any effect of cell viability, proliferation, respiration or inflammatory status. Materials and Methods Ethics Statement Label-free concentration of viable neurons, hESCs and cancer cells by means of acoustophoresis† Marina C. Zalis , a Juan F.

CONCLUSION We believe that this work contributes principal proof of concept showing that acoustophoresis has potential for use in clinical diagnostics of CTCs in cancer patients.
