Mesenchymal stem cells from tumor microenvironment favour breast cancer stem cell proliferation, cancerogenic and metastatic potential, via ionotropic purinergic signalling. Sci Rep 2017; 7:13162. [PMID: 29030596 PMCID: PMC5640614 DOI: 10.1038/s41598-017-13460-7] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2017] [Accepted: 09/21/2017] [Indexed: 12/26/2022] Open
Abstract
Interaction between tumor cells and the microenvironment is key in initiation, progression, and invasiveness of cancer. In particular, mesenchymal stem cells (MSCs) are recruited to the sites of developing tumors, thus promoting metastasis formation. Although it is well known that MSCs migrate and integrate in the tumor microenvironment (TME), their fate and function inside the tumor is still not clear. In this study, we analyzed the role played by MSCs in breast cancer oncogenesis. Data indicate that interaction of breast cancer cells with MSCs results in an increased proliferation and metabolic activity of breast cancer cells, partially due to MSC-derived microvesicles that are shed in the TME. Moreover, we addressed the question of whether we could modulate such interaction by acting on P2X-mediated intercellular communication. By inhibiting P2X-mediated purinergic signaling, we succeeded in reducing both the cancerogenic as well as the metastatic potential of breast cancer cells co-cultured with MSCs, in 2D as well as in 3D in vitro models. Data obtained demonstrate for the first time that the trophic effect of MSCs on breast cancer cell growth is exerted via ionotropic purinergic signaling, thus suggesting the inhibition of the purinergic signaling system as a potential target for therapeutic intervention.

Computational fluid dynamics modelling of microfluidic channel for dielectrophoretic BioMEMS application. ScientificWorldJournal 2014; 2014:961301. [PMID: 25136701 PMCID: PMC4129156 DOI: 10.1155/2014/961301] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2014] [Accepted: 05/30/2014] [Indexed: 12/02/2022] Open
Abstract
We propose a strategy for optimizing distribution of flow in a typical benchtop microfluidic
chamber for dielectrophoretic application. It is aimed at encouraging uniform flow
velocity along the whole analysis chamber in order to ensure DEP force is evenly applied
to biological particle. Via the study, we have come up with a constructive strategy in
improving the design of microfluidic channel which will greatly facilitate the use of DEP
system in laboratory and primarily focus on the relationship between architecture and
cell distribution, by resorting to the tubular structure of blood vessels. The design was
validated by hydrodynamic flow simulation using COMSOL Multiphysics v4.2a software.
Simulations show that the presence of 2-level bifurcation has developed portioning of
volumetric flow which produced uniform flow across the channel. However, further bifurcation
will reduce the volumetric flow rate, thus causing undesirable deposition of cell
suspension around the chamber. Finally, an improvement of microfluidic design with
rounded corner is proposed to encourage a uniform cell adhesion within the channel.

Abstract
We present a low cost microfluidic chip integrating 3D micro-chambers for the capture and the analysis of cells. This device has a simple design and a small footprint. It allows the implementation of standard biological protocols in a chip format with low volume consumption. The manufacturing process relies on hot-embossing of cyclo olefin copolymer, allowing the development of a low cost and robust device. A 3D design of microchannels was used to induce high flow velocity contrasts in the device and provide a selective immobilization. In narrow distribution channels, the liquid velocity induces a shear stress that overcomes adhesion forces and prevents cell immobilization or clogging. In large 3D chambers, the liquid velocity drops down below the threshold for cell attachment. The devices can be operated in a large range of input pressures and can even be handled manually using simple syringe or micropipette. Even at high flow injection rates, the 3D structures protect the captured cell from shear stress. To validate the performances of our device, we implemented immuno-fluorescence labeling and Fluorescence in Situ Hybridization (FISH) analysis on cancer cell lines and on a patient pleural effusion sample. FISH is a Food and Drug Administration approved cancer diagnostic technique that provides quantitative information about gene and chromosome aberration at the single cell level. It is usually considered as a long and fastidious test in medical diagnosis. This process can be easily implanted in our platform, and high resolution fluorescence imaging can be performed with reduced time and computer intensiveness. These results demonstrate the potential of this chip as a low cost, robust, and versatile tool adapted to complex and demanding protocols for medical diagnosis.

Abstract
Understanding the mechanisms of cell-cell interaction is a key unanswered question in modern pharmacology, given crosstalk defects are at the basis of many pathologies. Microfluidics represents a valuable tool for analyzing intercellular communication mediated by transmission of soluble signals, as occurring for example between neurons and glial cells in neuroinflammation, or between tumor and surrounding cells in cancer. However, the use of microfluidics for studying cell behavior still encompasses many technical and biological challenges. In this review, a state of the art of successes, potentials and limitations of microfluidics applied to key biological questions in modern pharmacology is analyzed and commented.

Abstract
Commercially available polydimethylsiloxane (PDMS) elastomers, such as Sylgard 184® are widely used in soft lithography and for microfluidic applications. These PDMS elastomers contain fillers to enhance their mechanical stability. The reinforcing fillers, often sub-micrometer small SiO(2) particles, tend to aggregate, swell with water, and thereby become cognoscible in a way that can strongly interfere with the visualization of micro-scale events taking place next to PDMS structures. As PDMS microfluidics are often used for studying cells and micro-/nanoparticles and for creating/handling nanodroplets, it has become highly desirable to employ a PDMS having high optical quality and that allows microscopy observation without artifacts. Here, we present a PDMS formulation that is free of fillers and has sufficiently low viscosity to perform a filtration step of the mixed prepolymers before curing. By molding a bi-layer microfluidic network (MFN), composed of a thin filler-free PDMS layer and a thicker Sylgard 184® backing layer, PDMS MFNs featuring both high optical quality and mechanical stability, can be fabricated.

Abstract
This article reviews the application of electric circuit methods for the analysis of pressure-driven microfluidic networks with an emphasis on concentration- and flow-dependent systems. The application of circuit methods to microfluidics is based on the analogous behaviour of hydraulic and electric circuits with correlations of pressure to voltage, volumetric flow rate to current, and hydraulic to electric resistance. Circuit analysis enables rapid predictions of pressure-driven laminar flow in microchannels and is very useful for designing complex microfluidic networks in advance of fabrication. This article provides a comprehensive overview of the physics of pressure-driven laminar flow, the formal analogy between electric and hydraulic circuits, applications of circuit theory to microfluidic network-based devices, recent development and applications of concentration- and flow-dependent microfluidic networks, and promising future applications. The lab-on-a-chip (LOC) and microfluidics community will gain insightful ideas and practical design strategies for developing unique microfluidic network-based devices to address a broad range of biological, chemical, pharmaceutical, and other scientific and technical challenges.

Abstract
The detection, isolation and sorting of cells are important tools in both clinical diagnostics and fundamental research. Advances in microfluidic cell sorting devices have enabled scientists to attain improved separation with comparative ease and considerable time savings. Despite the great potential of Lab-on-Chip cell sorting devices for targeting cells with desired specificity and selectivity, this field of research remains unexploited. The challenge resides in the detection techniques which has to be specific, fast, cost-effective, and implementable within the fabrication limitations of microchips. Adhesion-based microfluidic devices seem to be a reliable solution compared to the sophisticated detection techniques used in other microfluidic cell sorting systems. It provides the specificity in detection, label-free separation without requirement for a preprocessing step, and the possibility of targeting rare cell types. This review elaborates on recent advances in adhesion-based microfluidic devices for sorting, detection and enrichment of different cell lines, with a particular focus on selective adhesion of desired cells on surfaces modified with ligands specific to target cells. The effect of shear stress on cell adhesion in flow conditions is also discussed. Recently published applications of specific adhesive ligands and surface functionalization methods have been presented to further elucidate the advances in cell adhesive microfluidic devices.

Abstract
Generation of stable soluble-factor gradients in microfluidic devices enables studies of various cellular events such as chemotaxis and differentiation. However, many gradient devices directly expose cells to constant fluid flow and that can induce undesired responses from cells due to shear stress and/or wash out of cell-secreted molecules. Although there have been devices with flow-free gradients, they typically generate only a single condition and/or have a decaying gradient profile that does not accommodate long-term experiments. Here we describe a microdevice that generates several chemical gradient conditions on a single platform in flow-free microchambers which facilitates steady-state gradient profiles. The device contains embedded normally-closed valves that enable fast and uniform seeding of cells to all microchambers simultaneously. A network of microchannels distributes desired solutions from easy-access open reservoirs to a single output port, enabling a simple setup for inducing flow in the device. Embedded porous filters, sandwiched between the microchannel networks and cell microchambers, enable diffusion of biomolecules but inhibit any bulk flow over the cells.
