Combining Technologies To Separate Blood Cells Efficiently

Biomedical Engineering, Dongguk University, Seoul, SOUTH KOREA ABSTRACT The basic principles of acoustic cell and particle manipulation in chip integrated acoustic standing … 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 Neither did acoustophoresis affect cell proliferation or the ability of cells to be recultured for several passages ( Figure 4B). No significant immediate or long-term effects on proliferation could be detected in the DU145 prostate cancer cells subjected to acoustophoresis compared to the untreated cancer cells. 2015-08-07 bacteria) to 30µm (e.g., blood and cancer cells), in Fig. 1.1 the relevant length scale of bioparticles and lab on chip devices are presented. Particle manipulation can be roughly categorized into two different approaches i.e., passive (e.g., inertial microfluidics) and active techniques (e.g., acoustophoresis… Schematic representation of an acoustophoresis chip that is operated using frequency modulation for cancer cell enrichment. Sheath liquid buffer enters from the side inlet while sample containing 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. This flow-through separation approach, which utilize acoustophoretic forces Acoustophoresis does not affect cell viability or proliferation. To determine whether acoustophoresis had any detectable effect on the intrinsic properties of viable cancer cells, we measured cell viability at two temperatures (25.0 ± 0.5°C and 37.0 ± 0.5°C) subsequent to acoustophoretic processing.

Our results show that the three-step acoustophoresis method can be used for on-chip sample prep-aration in applications using uorescence-based cellular analysis. Materials and methods Microbead suspensions 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. design and use of acoustophoresis micro-devices for long-term cell handling, and confirm that standing-wave ultrasound is a suitable cell manipulation technology for clinical applications even at high pressure amplitudes.

M any types of cancer are diagnosed at the early stages of the disease, enabling treatment with curative intent. However, many patients succumb due to metastases, and the 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.

As a growing corpus of evidence supports that cancer cells exhibit distinct mechanical phenotypes from healthy cells, expanding the method from size to mechanical sensing could represent a pertinent and innovative tool for cancer research. Traditional acoustophoresis cell handling typically displays a lower size limit of about 2 micrometers. However, more recent developments have advanced acoustofluidics to enable access also to bacteria and submicron vesicles where the rising interest in extra cellular vesicles and the link to disease biomarkers now is a major focus area.
