Abstract
Microfluidics is an essential technique used in the development of in vitro models for mimicking complex biological systems. The microchip with microfluidic flows offers the precise control of the microenvironment where the cells can grow and structure inside channels to resemble in vivo conditions allowing a proper cellular response investigation. Hence, this study aimed to develop low-cost, simple microchips to simulate the shear stress effect on the human umbilical vein endothelial cells (HUVEC). Differentially from other biological microfluidic devices described in the literature, we used readily available tools like heat-lamination, toner printer, laser cutter and biocompatible double-sided adhesive tapes to bind different layers of materials together, forming a designed composite with a microchannel. In addition, we screened alternative substrates, including polyester-toner, polyester-vinyl, glass, Permanox® and polystyrene to compose the microchips for optimizing cell adhesion, then enabling these microdevices when coupled to a syringe pump, the cells can withstand the fluid shear stress range from 1 to 4 dyne cm2. The cell viability was monitored by acridine orange/ethidium bromide (AO/EB) staining to detect live and dead cells. As a result, our fabrication processes were cost-effective and straightforward. The materials investigated in the assembling of the microchips exhibited good cell viability and biocompatibility, providing a dynamic microenvironment for cell proliferation. Therefore, we suggest that these microchips could be available everywhere, allowing in vitro assays for daily laboratory experiments and further developing the organ-on-a-chip concept.

Abstract
Health risks associated with exposure to ambient particulate matter (PM) are a major concern around the world. Adverse PM health effects have been proposed to be linked to oxidative stress through the generation of reactive oxygen species (ROS). In vitro cellular assays can provide insights into components or characteristics of PM that best account for its toxicity at a cellular level. However, most current assays report cell population averages and are mostly time endpoint measurements and thus provide no temporal information. This poses limitations on our understanding of PM health effects. In this study, we developed a microfluidic assay that can measure cellular ROS responses at the single-cell level and evaluate temporal dynamic behavior of single cells. We first established a protocol that enables culturing cells in our microfluidic platform and that can provide reproducible ROS readouts. We further examined the heterogeneous ROS responses of cell populations and tracked the dynamics of individual cellular responses upon exposure to different concentrations of PM extracts. Our results show that in an alveolar macrophage cell line, cellular ROS responses are highly heterogeneous. ROS responses from different cells can vary over an order of magnitude, and large coefficients of variation at each timepoint measurement indicate a high variability. The dynamic behavior of single-cell responses is strongly dependent on PM concentrations. Our work serves as a proof-of-principle demonstration of the capability of our microfluidic technology to study time-resolved single-cell responses upon PM exposure. We envision applying this high-resolution, high-content assay to investigate a wide array of single-cell responses (beyond ROS) upon exposure to different types of PM in the future.

Abstract
A microfluidic co-culture system, consisting of mouse embryonic stem cells (mESCs)/OP9 cells, was evaluated as a platform for studying hematopoietic differentiation mechanisms in vitro. mESC differentiation into blood cells was achieved in a microchannel that had the minimum size necessary to culture cells. The number of generated blood cells increased or decreased based on the nitric oxide (NO) donor or inhibitor used. Conditioned medium from OP9 cell cultures also promoted an increase in the number of blood cells. The number of generated blood cells under normal medium flow conditions was lower than that observed under the static condition. However, when using a conditioned medium, the number of generated blood cells under flow conditions was the same as that observed under the static condition. We conclude that secreted molecules from OP9 cells have a large influence on the differentiation of mESCs into blood cells. This is the first report of a microfluidic mESC/OP9 co-culture system that can contribute to highly detailed hematopoietic research studies by mimicking the cellular environment.

Abstract
Development of a three-dimensional (3D) vascular co-cultivation system is one of the major challenges to provide an advanced analytical platform for studying blood vessel related diseases. To date, however, the in vivo-like vessel system has not been fully realized due to the difficulty of co-cultivation of the cells with orthogonal alignment. In this study, we report the utilization of microfabrication technology to construct biomimetic 3D co-cultured vasculature. First, microwrinkle patterns whose direction was perpendicular to the axis of a circular microfluidic channel were fabricated, and vascular smooth muscle cells (VSMCs) were cultured inside the microchannel, leading to an in vivo-like circumferential VSMC layer. Then, human umbilical vein endothelial cells (HUVECs) were co-cultured on the circumferentially aligned VSMC, and the success of double layer formation of HUVEC-VSMC in the circular microchannel could be monitored. After HUVEC cultivation, we applied shear flow in order to induce the orientation of HUVEC parallel to the axis, and the analysis of orientation angle and spreading area of HUVECs indicated that they were changed by shear stress to be aligned to the direction of flow. Thus, the HUVEC and VSMC layer could be aligned with a distinct direction. The expression level of VE-Cadherin located at the boundary of HUVECs implies in vivo-like vascular behavior. The proposed in vitro microfluidic vascular assay platform would be valuable for studying vascular diseases with high reliability due to in vivo-likeness.

Abstract
Nanoparticles have been widely utilized to deliver drugs from blood vessels to target tissues. A crucial issue concerning nanoparticle-based drug delivery is to discuss the relationship between experimentally-obtained permeability and physical parameters. Although nanoparticles can permeate vascular pores, because the size and shape of the pores are essentially non-uniform, conventional animal testing and recent cell-based microfluidic devices are unable to precisely evaluate the effects of physical parameters (e.g. pore size and nanoparticle size) on permeation. In this study, we present a membrane-integrated microfluidic device to study permeation of nanoparticles through straight micropores. Porous membranes possessing uniform straight pores were utilized. The effects of pore size and pressure difference across the pores on nanoparticle permeation were examined. The experimentally determined permeability coefficient of 1.0 μm-pore membrane against 100 nm-diameter nanoparticles agreed well with the theoretical value obtained for convectional permeation. Our method can be utilized to clarify the relationship between the experimentally-obtained permeability and physical parameters, and will help rational design of nanomedicines.

Abstract
There is an urgent need to develop novel in-vitro models to mimic the disease conditions in pulmonary hypertension (PH). We developed a microfluidic cell culture device for PH studies that withstood high shear stress. Techniques were also developed for cell recovery from the microchannel and mRNA isolation from the collected cells. Using this device, we found that shear stress caused a 7.5-fold increase in the transcription levels of a PH-related molecule, Cyclin D1.

Abstract
We developed a microfluidic model of microcirculation containing both blood and lymphatic vessels for examining vascular permeability. The designed microfluidic device harbors upper and lower channels that are partly aligned and are separated by a porous membrane, and on this membrane, blood vascular endothelial cells (BECs) and lymphatic endothelial cells (LECs) were cocultured back-to-back. At cell-cell junctions of both BECs and LECs, claudin-5 and VE-cadherin were detected. The permeability coefficient measured here was lower than the value reported for isolated mammalian venules. Moreover, our results showed that the flow culture established in the device promoted the formation of endothelial cell-cell junctions, and that treatment with histamine, an inflammation-promoting substance, induced changes in the localization of tight and adherens junction-associated proteins and an increase in vascular permeability in the microdevice. These findings indicated that both BECs and LECs appeared to retain their functions in the microfluidic coculture platform. Using this microcirculation device, the vascular damage induced by habu snake venom was successfully assayed, and the assay time was reduced from 24 h to 30 min. This is the first report of a microcirculation model in which BECs and LECs were cocultured. Because the micromodel includes lymphatic vessels in addition to blood vessels, the model can be used to evaluate both vascular permeability and lymphatic return rate.

Abstract
Nanotechnology-based drug delivery systems hold promise for innovative medical treatment of cancers. While drug materials are constantly under development, there are no practical cell-based models to assess whether these materials can reach the target tissue. Recently developed microfluidic systems have revolutionized cell-based experiments. In these systems, vascular endothelial cells and interstitium are set in microchannels that mimic microvessels. Drug permeability can be assayed in these blood vessel models under fluidic conditions that mimic blood flow. In this review, we describe device fabrication, disease model development, nanoparticle permeability assays, and the potential utility of these systems in the future.

Abstract
Here, we report the antiproliferative/cytotoxic properties of 8-hydroxyquinoline (8-HQ) derivatives on HeLa cells in the presence of transition metal ions (Cu(2+), Fe(3+), Co(2+), Ni(2+)). Two series of ligands were tested, the arylvinylquinolinic L1-L8 and the arylethylenequinolinic L9-L16, which can all interact with metal ions by virtue of the N,O donor set of 8-HQ; however, only L9-L16 are flexible enough to bind the metal in a multidentate fashion, thus exploiting the additional donor functions. L1-L16 were tested for their cytotoxicity on HeLa cancer cells, both in the absence and in the presence of copper. Among them, the symmetric L14 exhibits the highest differential activity between the ligand alone (IC50 = 23.7 μM) and its copper complex (IC50 = 1.8 μM). This latter, besides causing a significant reduction of cell viability, is associated with a considerable accumulation of the metal inside the cells. Metal accumulation is also observed when the cells are incubated with L14 complexed with other late transition metal ions (Fe(3+), Co(2+), Ni(2+)), although the biological response of HeLa cells is different. In fact, while Ni/L14 and Co/L14 exert a cytostatic effect, both Cu/L14 and Fe/L14 trigger a caspase-independent paraptotic process, which results from the induction of a severe oxidative stress and the unfolded protein response.

Abstract
Heterocycles bearing nitrogen, sulphur and thiazole moieties constitute the core structure of a number of biologically interesting compounds. Benzothiazole, a group of xenobiotic compounds containing a benzene ring fused with a thiazole ring, are used worldwide for a variety of therapeutic applications. Benzothiazole and their heterocyclic derivatives represent an important class of compounds possessing a wide spectrum of biological activities. The myriad spectrum of medicinal properties associated with benzothiazole related drugs has encouraged the medicinal chemists to synthesize a large number of novel therapeutic agents. Several analogues containing benzothiazole ring system exhibit significant antitumour, antimicrobial, antidiabetic, anti-inflammatory, anticonvulsant, antiviral, antioxidant, antitubercular, antimalarial, antiasthmatic, anthelmintic, photosensitizing, diuretic, analgesic and other activities. This article is an attempt to present the research work reported in recent scientific literature on different pharmacological activities of benzothiazole compounds.

Abstract
We present a method that allows patterning cells and shear flow conditions for endothelial cell based assays. This method is novel in combining (1) cell culture on the surface of a substrate both topographically and chemically patterned; (2) multi-shear flow assays after covering the cell substrate with a microfluidic cover plate containing microchannels of different channel widths, and (3) conventional immunostaining assays after removal of the cover plate. This method has the advantage of performing cell cultures and immunoassays in standard cell biology environments with open access, facilitating the formation of confluent cell layers and the observation of cell responses to shear-flow and drug stimulations. To obtain multi-shear stress conditions, a single channel with stepwise increasing channel widths was patterned on the surfaces of both the substrate and the microfluidic cover plate. As results, we observed excellent viability of endothelial cells in the whole range of applied shear stresses (0-25 dyn cm(-2)) and shear stress dependent cytoskeleton remoulding, activation of von Willebrand factor (vWF), and re-organisation of angiogenesis factors such as tetra peptide acetyl-Ser-Asp-Lys-Pro (AcSDKP) of endothelial cells. To validate this approach for drug analysis, we also studied drug effects under shear stress conditions. Our results indicate that the drug effect of combretastatin A-4, an anti-tumour vascular targeting drug, could be significantly enhanced under shear flow conditions.

Abstract
Most studies of cancer metastasis focus on cancer cell invasion utilizing adhesion assays that are performed independently, and are thus limited in their ability to mimic complex cancer metastasis on a chip. Here we report the development of an integrated cell-based microfluidic chip for intra- and extravasation that combines two assays on one chip for the study of the complex cascade of cancer metastasis. This device consists of two parts; one is an intravasation chamber for the three-dimensional (3-D) culture of cancer cells using a Matrigel matrix, and the other is an extravasation chamber for the detection of metastasized cancer cells by adhesion molecules expressed by epithelial cells. In this novel system, the intravasation and extravasation processes of cancer metastasis can be studied simultaneously using four screw valves. Metastatic LOVO and non-metastatic SW480 cells were used in this study, and the invasion of LOVOs was found to be higher compared to SW480. In contrast, invasion of cells treated with metalloproteinase (MMP) inhibitors decreased within the intravasation chamber. Degraded cancer cells from the intravasation chamber were detected within the extravasation chamber under physiological conditions of shear stress, and differences in binding efficiency were also detected when CA19-9 antibody, an inhibitor of cancer cell adhesion, was used to treat degraded cancer cells. Our results support the potential usefulness of this new 3D cell-based microfluidic system as a drug screening tool to select targets for the development of new drugs and to verify their effectiveness.

Abstract
Recently, interest in single cell analysis has increased because of its potential for improving our understanding of cellular processes. Single cell operation and attachment is indispensable to realize this task. In this paper, we employed a simple and direct method for single-cell attachment and culture in a closed microchannel. The microchannel surface was modified by applying a nonbiofouling polymer, 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer, and a nitrobenzyl photocleavable linker. Using ultraviolet (UV) light irradiation, the MPC polymer was selectively removed by a photochemical reaction that adjusted the cell adherence inside the microchannel. To obtain the desired single endothelial cell patterning in the microchannel, cell-adhesive regions were controlled by use of round photomasks with diameters of 10, 20, 30, or 50 μm. Single-cell adherence patterns were formed after 12 h of incubation, only when 20 and 30 μm photomasks were used, and the proportions of adherent and nonadherent cells among the entire UV-illuminated areas were 21.3%±0.3% and 7.9%±0.3%, respectively. The frequency of single-cell adherence in the case of the 20 μm photomask was 2.7 times greater than that in the case of the 30 μm photomask. We found that the 20 μm photomask was optimal for the formation of single-cell adherence patterns in the microchannel. This technique can be a powerful tool for analyzing environmental factors like cell-surface and cell-extracellular matrix contact.

Abstract
This report describes a direct approach for cell micropatterning in a closed glass microchannel. To control the cell adhesiveness inside the microchannel, the application of an external stimulus such as ultraviolet (UV) was indispensible. This technique focused on the use of a modified 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer, which is known to be a non-biofouling compound that is a photocleavable linker (PL), to localize cells via connection to an amino-terminated silanized surface. Using UV light illumination, the MPC polymer was selectively eliminated by photochemical reaction that controlled the cell attachment inside the microchannel. For suitable cell micropatterning in a microchannel, the optimal UV illumination time and concentration for cell suspension were investigated. After selective removal of the MPC polymer through the photomask, MC-3T3 E1 cells and vascular endothelial cells (ECs) were localized only to the UV-exposed area. In addition, the stability of patterned ECs was also confirmed by culturing for 2 weeks in a microchannel under flow conditions. Furthermore, we employed two different types of cells inside the same microchannel through multiple removal of the MPC polymer. ECs and Piccells were localized in both the upper and down streams of the microchannel, respectively. When the ECs were stimulated by adenosine triphosphate (ATP), NO was secreted from the ECs and could be detected by fluorescence resonance energy transfer (FRET) in Piccells, which is a cell-based NO indicator. This technique can be a powerful tool for analyzing cell interaction research.

Abstract
In this work, we demonstrated that biological cells could be cultured in a continuous-perfusion glass microchip system for drug screening. We used mouse Col1a1GFP MC-3T3 E1 osteoblastic cells, which have a marker gene system expressing green fluorescent protein (GFP) under the control of osteoblast-specific promoters. With our microchip-based cell culture system, we realized automated long-term monitoring of cells and sampling of the culture supernatant system for osteoblast differentiation assay using a small number of cells. The system successfully monitored cells for 10 days. Under the 3D microchannel condition, shear stress (0.07 dyne/cm(2) at a flow rate of 0.2 microL/min) was applied to the cells and it enhanced the GFP expression and differentiation of the osteoblasts. Analysis of alkaline phosphatase (ALP), which is an enzyme marker of osteoblasts, supported the results of GFP expression. In the case of differentiation medium containing bone morphogenetic protein 2, we found that ALP activity in the culture supernatant was enhanced 10 times in the microchannel compared with the static condition in 48-well dishes. A combined system of a microchip and a cell-based sensor might allow us to monitor osteogenic differentiation easily, precisely, and noninvasively. Our system can be applied in high-throughput drug screening assay for discovering osteogenic compounds.

Abstract
Integration of various chemical devices and complex operations onto a microchip, which is often referred to as a micro total analysis system (mu-TAS) or lab-on-a-chip, creates extremely efficient devices that exploit the advantages of a microspace. Furthermore, as the scale of the fluidic microvolume is roughly proportional to living cell sizes and processing capabilities, cells and micro chemical systems can be combined to develop practical prototypical microdevices. This approach has led to development of tools for investigating cellular functions, biochemical reactors and bioassay systems, as well as hybrid bio/artificial tissue engineered organs. Recently, bio-microactuators exploiting mechanical properties of cells powered without external energy sources have also been reported. This review focuses on new technologies involving cell-based devices on microchips, with a special emphasis on bio-microactuators. Firstly, we review systems to place and handle cells on a microchip. Secondly, we review bio-microactuators developed using single or a few driving cells. Finally, we review bio-microactuators developed using numerous cells or tissue to generate stronger forces. Understanding fundamental concepts behind the distinct features and performance characteristics of these cell-based micro-systems will lead to development of new devices that will be exploited in various fields in the future.
