Cell line was routinely grown in tissue culture flasks (75 cm2) and kept in a humidified atmosphere of 5% CO2 at 37 °C. All examined cell lines was tested against mycoplasma contamination with microbiological assays. The research was carried out using the normal cell line L929—mouse fibroblast and cancer cells: HeLa—human cervical cancer, A549—human lung cancer. All of the stock solutions of the tested compounds were dissolved in DMSO.

Zirconia Bioactivity and Cytocompatibility

Check if the same lab product or an alternative is used in the 5 most similar protocols
First, cytocompatibility of plain zirconia discs was evaluated in a pilot study (n=6), and no statistically significant differences in L929 cell viability were found when they were seeded on zirconia or polystyrene surfaces for up to 7 days (data not shown). Therefore, the following experimental groups were established for biological assays: Zr -zirconia discs; and Zr+BS -zirconia discs subjected to BS treatment (n=6). The samples were adapted to a metallic device between two silicon rings to keep the discs in position and to standardize the seeding area. The sets were sterilized in ethylene oxide and placed individually in wells of 24-well plates. Then, L929 mouse fibroblast cells Zirconia-coated bioactive glass (subcutaneous connective tissue; ATCC® CCL1™, Manassas, VI, USA) were seeded on material surfaces in Dulbecco's Modified Eagle's Medium (DMEM; supplemented with 100 IU/mL penicillin, 100 μg/mL streptomycin, and 2 mmol/L glutamine; GIBCO, Grand Island, NY, USA), supplemented with 10% fetal bovine serum (FBS; GIBCO). One 30-μL drop of culture medium containing 3 x 104 cells was applied exclusively to material surfaces, followed by a 30-min incubation time at 37 °C and 5% CO2, to allow for cell attachment in a 50% confluence pattern. Thereafter, 1 mL of culture medium was added to the sets, followed by further cultivation for up to 7 days.

Two adherent cell lines—murine L929 fibroblast (ATCC® CCL-1™, American Type Culture Collection, Manassas, VA, USA) and MCF-7 human breast adenocarcinoma (ATCC® HTB-22™, American Type Culture Collection, Manassas, VA, USA)—were chosen for cytocompatibility studies of the h-BN_AuNP nanocomposite.
For morphology analyses (phase contrast and holographic microscopy), cells of each line were seeded into T25 flasks (Sarstedt, Nümbrecht, Germany) and maintained in standard cell culture conditions at 37 °C, 5% CO2, 95% humidity. Complete Dulbecco’s Modified Eagle Medium (DMEM) culture medium supplemented with 10% heat inactivated fetal bovine serum (FBS) (PAA Laboratories GmbH, Pasching, Austria), 2 mM l-glutamine, 50 IU mL−1 penicillin and 50 µg mL−1 streptomycin (Sigma-Aldrich, St. Louis, MO, USA) was used in the study.
For cytocompatibility analysis, the cells were seeded into 96-well plates (Corning Inc., New York, NY, USA) and cultured for 24, 48 and 72 h in standard conditions mentioned above. All cell cultures were monitored with a Nikon TS-100 microscope (Nikon, Melville, NY, USA).

Virus Infection Assay in L929 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mouse L929 cells (ATCC CCL-1) were from the American Type Culture Collection and were grown as previously described (26 (link), 29 ). The generation and maintenance of L929 cells stably expressing a luciferase reporter gene (pGL4.32 or pGL4.50 plasmid) or the CAT reporter gene (pTWU54 plasmid) were produced as previously described (26 (link), 30 (link)). VSV field isolates 22–20 and 22–25 were generous gifts from Dr. Philip Marcus (University of Connecticut) and have been previously described (31 (link), 32 (link)). The heat resistant (HR) strain of the Indiana serotype of VSV was used as the wt virus, and its mutant T1026R1, a temperature-stable revertant of T1026, was isolated by Stanners et al (24 (link)). All viruses were grown on Vero cells as previously described (24 (link)). Cells were infected with each virus at a multiplicity of infection (MOI) of 5 plaque forming units (PFU)/cell unless otherwise stated. Virus was adsorbed in MEM for 1 hour at 37 °C in the absence of serum, after which complete medium was added.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
