Title: Matrix-Assisted Pulsed laser Evaporation-deposited Rapamycin Thin Films Maintain Antiproliferative Activity
Matrix-assisted pulsed laser evaporation (MAPLE) has many benefits over conventional methods (e.g., dip-coating, spin coating, and Langmuir–Blodgett dip-coating) for manufacturing coatings containing pharmacologic agents on medical devices. In particular, the thickness of the coating that is applied to the surface of the medical device can be tightly controlled. In this study, MAPLE was used to deposit rapamycin-polyvinylpyrrolidone (rapamycin-PVP) thin films onto silicon and borosilicate optical glass substrates. Alamar Blue and PicoGreen studies were used to measure the metabolic health and DNA content of L929 mouse fibroblasts as measures of viability and proliferation, respectively. The cells on the MAPLE-deposited rapamycin-PVP surfaces exhibited 70.6% viability and 53.7% proliferation compared to a borosilicate glass control. These data indicate that the antiproliferative properties of rapamycin were maintained after MAPLE deposition.  more » « less

  1. Fabrication of microfluidic devices by photolithography generally requires specialized training and access to a cleanroom. As an alternative, 3D printing enables cost-effective fabrication of microdevices with complex features that would be suitable for many biomedical applications. However, commonly used resins are cytotoxic and unsuitable for devices involving cells. Furthermore, 3D prints are generally refractory to elastomer polymerization such that they cannot be used as master molds for fabricating devices from polymers ( e.g. polydimethylsiloxane, or PDMS). Different post-print treatment strategies, such as heat curing, ultraviolet light exposure, and coating with silanes, have been explored to overcome these obstacles, but none have proven universally effective. Here, we show that deposition of a thin layer of parylene, a polymer commonly used for medical device applications, renders 3D prints biocompatible and allows them to be used as master molds for elastomeric device fabrication. When placed in culture dishes containing human neurons, regardless of resin type, uncoated 3D prints leached toxic material to yield complete cell death within 48 hours, whereas cells exhibited uniform viability and healthy morphology out to 21 days if the prints were coated with parylene. Diverse PDMS devices of different shapes and sizes were easily cast from parylene-coated 3D printed molds without any visible defects. As a proof-of-concept, we rapid prototyped and tested different types of PDMS devices, including triple chamber perfusion chips, droplet generators, and microwells. Overall, we suggest that the simplicity and reproducibility of this technique will make it attractive for fabricating traditional microdevices and rapid prototyping new designs. In particular, by minimizing user intervention on the fabrication and post-print treatment steps, our strategy could help make microfluidics more accessible to the biomedical research community.

  2. Abstract

    Bone marrow derived mesenchymal stem cells (BM‐MSC) is a promising alternative cell source to primary hepatocytes because of their ability to differentiate into hepatocyte‐like cells. However, their inability to differentiate efficiently and potential to turn into myofibroblasts restrict their applications. This study developed a plate coating from the liver extracellular matrix (ECM) and investigated its ability in facilitating the BM‐MSCs proliferation, hepatic differentiation, and hepatocyte‐specific functions duringin vitroculture. After 28‐day culture, BM‐MSCs on the ECM coating showed hepatocyte‐like morphology, and certain cells took up low‐density lipoprotein. Synthesis of albumin, urea, and anti‐alpha‐fetoprotein, as well as expression of certain hepatic markers, in cells cultured on ECM were higher than cells cultured on non‐coated and Matrigelcoated plates. mRNA levels of CYP3A4, albumin, CK18, and CYP7A1 in cells on ECM coating were significantly higher than cells cultured on the non‐coating environment. In conclusion, viability and hepatogenic differentiation of BM‐MSCs cultured on both Matrigel and ECM coating were significantly enhanced compared with those cultured on non‐coated plates. Moreover, the liver ECM coating induced additional metabolic functions relative to the Matrigel coating. The liver ECM hydrogel preserves the natural composition, promotes simple gelling, induces efficient stem cell hepatogenic differentiation, and may have uses as an injectable intermedium for hepatocytes. © 2017 Wiley Periodicals, Inc.

    Nutrition and growth are strongly linked, but not much is known about how nutrition leads to growth. To understand the connection between nutrition through the diet, growth, and proliferation, we need to study the phenotypes resulting from the activation and inhibition of central metabolic pathways. One of the most highly conserved metabolic pathways across eukaryotes is the Target of Rapamycin (TOR) pathway, whose primary role is to detect the availability of nutrients and to either induce or halt cellular growth. Here we used the model organism Drosophila melanogaster ( D . mel .) and three non-model Drosophila species with different dietary needs, Drosophila guttifera ( D . gut .), Drosophila deflecta ( D . def .), and Drosophila tripunctata ( D . tri .), to study the effects of dietary amino acid availability on fecundity and longevity. In addition, we inhibited the Target of Rapamycin (TOR) pathway, using rapamycin, to test how the inhibition interplays with the nutritional stimuli in these four fruit fly species. We hypothesized that the inhibition of the TOR pathway would reverse the phenotypes observed under conditions of overfeeding. Our results show that female fecundity increased with higher yeast availability in all four species but decreased in response to TOR inhibition. The longevity data were more varied: most species experienced an increase in median lifespan in both genders with an increase in yeast availability, while the lifespan of D . mel . females decreased. When exposed to the TOR inhibitor rapamycin, the life spans of most species decreased, except for D . tri , while we observed a major reduction in fecundity across all species. The obtained data can benefit future studies on the evolution of metabolism by showing the potential of using non-model species to track changes in metabolism. Particularly, our data show the possibility to use relatively closely related Drosophila species to gain insight on the evolution of TOR signaling.

  4. Abstract

    Radioactive waste immobilization is a means to limit the release of radionuclides from various waste streams into the environment over a timescale of hundreds to many thousands of years. Incorporation of radionuclide-containing wastes into borosilicate glass during vitrification is one potential route to accomplish such immobilization. To facilitate comparisons and assessments of reproducibility across experiments and laboratories, a six-component borosilicate glass (Si, B, Na, Al, Ca, Zr) known as the International Simple Glass (ISG) was developed by international consensus as a compromise between simplicity and similarity to waste glasses. Focusing on a single glass composition with a multi-pronged approach utilizing state-of-the-art, multi-scale experimental and theoretical tools provides a common database that can be used to assess relative importance of mechanisms and models. Here we present physical property data (both published and previously unpublished) on a single batch of ISG, which was cast into individual ingots that were distributed to the collaborators. Properties from the atomic scale to the macroscale, including composition and elemental impurities, phase purity, density, thermal properties, mechanical properties, optical and vibrational properties, and the results of molecular dynamics simulations are presented. In addition, information on the surface composition and morphology after polishing is included. Although the existing literature on the alteration of ISG is not extensively reviewed here, the results of well-controlled static alteration experiments are presented here as a point of reference for other performance investigations.

  5. BSE mosaics of mushes and experimental products. Abstract: "We conducted experiments to study melt migration in crystal-rich mushes, with application to magma ascent within transcrustal magma reservoirs. Mushes with crystal volume fractions of 0.59 to 0.83 were prepared by hot-pressing crushed borosilicate glass mixed with different amounts quartz sand particles. Each experimental sample comprises stacked disks of mush and soda-lime glass, a proxy for crystal-free magma. Samples were subjected to confining pressures of 100 to 300 MPa and a temperature of 900°C (above the glass transition temperatures of the borosilicate and soda-lime glasses) for up to 6 h. The bottom and circumference of the mush and soda lime disks experience the confining pressure, but the top of the mush disks are at room pressure, resulting in a pore-pressure gradient across the mush layer. Following cooling and decompression, we determined the area fraction and morphology of soda-lime melt that migrated into the mush layer during experiments. Melt fraction is more strongly correlated to crystal fraction than pore-pressure gradient, increasing with crystal fraction before sharply decreasing as crystal fractions exceed 0.8. This change at 0.8 coincides with the transition from crystals in the mush moving during soda-lime migration to crystals forming a continuous rigid network. In our experiments, melt migration occurred by viscous fingering, but near the mobile-to-rigid transition, melt migration is enhanced by additional capillary action. Our results indicate that magma migration may peak when rigid mushes “unlock” to become mobile. This transition may mark an increase in magma migration, a potential precursor to volcanic unrest and eruption." Imaging: "Transverse sections cut from the top and/or bottom of the vacuum hot-pressed mushes were polished, carbon-coated, and imaged in BSE mode using the JEOL JXA-8530FPlus Electron Probe Microanalyzer (EPMA) at UMN (15 kV, 10 nA). About ten 50x magnification images were taken per sample and then compiled into BSE mosaics using Affinity Designer. The different compositions of the borosilicate glass and crystalline materials are distinguishable by greyscale in BSE images. [...] Following each experiment, sample assemblies were cut longitudinally along the cylindrical axis to produce sections for microstructural analysis. Scored samples (pHi-19s, Int-20s, Lo-21s) were cut again to produce sections tangential to the sample cylinder. Cut sections were vacuum impregnated with EpoFix resin and hand-polished on diamond lapping film from 30 to 0.5 μm grit. Polished and carbon-coated samples were imaged in BSE mode in the EPMA at UMN (15 kV, 10 nA). The different compositions of the soda-lime glass, borosilicate glass, and crystalline materials are distinguishable by greyscale in BSE images. Twenty to forty 50x magnification images were taken per sample and then compiled into sample-scale BSE mosaics using Affinity Designer."
