Nontransformed porcine jejunal epithelial cells (IPEC-J2) were grown in co-culture media that included Dulbecco’s minimal essential medium:nutrient mixture F-12 (with L-glutamine and 15 mmol/L HEPES, catalog 10-092-CM; Corning, Corning, NY) supplemented with 5 μg/mL each of insulin, transferrin, and selenium (ITS Premix universal culture supplement, catalog 354350; Corning), epidermal growth factor (5 ng/mL, catalog 354052; Corning), penicillin (50,000 IU/mL), streptomycin (50,000 mg/mL) (100× penicillin-streptomycin solution, catalog 30002CI; Corning), and 5% porcine serum (catalog 26250084; Thermo Fischer, Waltham, MA), and incubated at 37°C in 5% CO2. Cells were seeded onto permeable polycarbonate filters (0.4-μm pore size, either 0.6 cm2 or 4.67cm2; catalog PIHP01250 and PIHP03050, respectively; Millipore Sigma, Burlington, MA) and cultured until confluent (TEER, ≥2000 Ω × 0.6 cm2 or ≥1300 Ω × 4.67 cm2). TEER was measured using an EVOM2 epithelial voltohmmeter with chopstick electrodes (World Precision Instruments, Sarasota, FL). For immunofluorescence assessment of C parvum burden, IPEC-J2 cells were seeded onto 8-well chamber slides (Nunc Lab-Tek II, catalog 154534; Thermo Fisher, Waltham, MA) and grown to confluence over a period of 3–4 days before use. IPEC-J2 cells were used at passages 38–50. Media was changed every 3–4 days.

The chondrogenic differentiation capacity of the 3D and 2D expanded hPDCs was determined based on a micromass assay as described earlier [41 (link)]. Briefly, quadruplicate 10 μl micro-masses containing 200,000 cells each were made in 24-well plates for both 2D and 3D expanded cells and incubated overnight in CM. Subsequently the medium was replaced by chondrogenic inductive medium based on DMEM-F12 (Life Technologies) supplemented with 2% FBS, 1% antibiotic–antimycotic, 1X insulin, transferrin, selenous acid (ITS+) Premix universal Culture Supplement (Corning), 100 nM Dexamethasone, 10 μM Y27632 (Axonmedchem), 50 μg/ml Ascorbic Acid, 40 μg/ml Proline (Sigma) and 10 ng/ml transforming growth factor beta 1 (TGFβ1) (Peprotech) [41 (link)]. Chondrogenic medium was refreshed every 2 days for 7 days after which the micro-masses were rinsed with PBS and fixed with ice cold methanol for 1 hour at 4°C. Subsequent rinsing steps with PBS and MiliQ water were followed by staining for 1 hour with a 0.1% Alcian Blue solution (in 0.1 M HCl). Non-specific dye was thereafter removed and a 6M guanidine hydrochloride solution was added overnight to dissolve the dye bound to the glycosaminoglycans present and quantification was performed by measuring the resulting absorbance at 620nm.

Tissue samples were disaggregated with scalpel, washed in DMEM with 1x Gibco® Antibiotic-Antimycotic solution (Thermo Fisher Scientific, USA), and fractured further by pipetting. Tumor cells were released from the tissues by enzymatic treatment with Accutase solution (Thermo Fisher Scientific, USA) for 20 min at 37°C on rotating platform in a humidified atmosphere maintained at 5% CO2. At the end of incubation, the cells were pelleted by centrifugation (5 min, 1600 rpm).

Tissue-engineered total disc replacements—eDAPS (endplate-modified Disc-Like Angle-Ply Structures)—were fabricated at a size physiologically relevant for disc replacement in goat cervical spines [Gullbrand et al., Science Translational Medicine 2018 ] by combining an AF-replacement (layers of electrospun 90 kDa PCL seeded with goat bone marrow-derived MSCs), a NP-replacement (core of 4% agarose hydrogel seeded with goat bone marrow-derived MSCs), and an acellular endplate analog (large salt-leached PCL scaffolds) according to our established methods [Gullbrand et al., Acta Biomaterialia 2018 (link); Gullbrand et al., Science Translational Medicine 2018 ]. For this study, the PCL endplate analogs were either uncoated (n = 4 eDAPS) or HA-coated (n =4 eDAPS) for 7 days. eDAPS were cultured in chondrogenic media containing 10 ng/ml TGF-β3 (Dulbecco’s modified Eagle’s medium (DMEM) containing 1% penicillin/streptomycin/fungizone (PSF, Antibiotic-Antimycotic; Gibco), 0.1 mM dexamethasone, 50 μg/ml Ascorbate-2-phosphate, 40 μg/ml L-Proline, 100 μg/ml sodium pyruvate, 1% ITS+ Premix universal culture supplement (Corning, 254352), 1.25 mg/ml bovine serum albumin, and 5.3 μg/ml linoleic acid-albumin) and left to grow at standard culture conditions with constant mechanical agitation until their removal from culture at 10 weeks.

The mouse limb bud cell line, MLB13MYC clone 14, was used for micromass culture.(29 (link)) Briefly, cells were plated at a density of 2 × 105 cells/7.5 μL drop and maintained in DMEM with 10% FBS, 100 IU/mL penicillin, and 100 μg/mL streptomycin. After 1 day in culture, the medium was replaced with chondrogenic medium (DMEM supplemented with 1% FBS, 50 μg/mL ascorbic acid, 0.1 μM dexamethasone, 40 μg/ml L-proline, 1 mM sodium pyruvate, ITS+ Premix Universal Culture Supplement [Corning Inc., Corning, NY, USA], 100 IU/mL penicillin, and 100 μg/mL streptomycin) with or without 50 ng/mL GDF6. Culture medium was replaced every 2 to 3 days. One week after stimulation, the micromass cultures were fixed and stained with Alcian blue overnight. Quantification of Alcian blue dye was determined at 620 nm after extraction with 6M guanidine-HCl.(16 (link)) For each condition, 3 replicates were performed in parallel.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Senescent preadipocytes at Day 5 and control untreated cells were cultured in conditioned medium (serum-free), supplemented with ITS Premix Universal Culture Supplement (Corning) for 24 h. The conditioned medium was collected, centrifuged to remove cell debris and stored at –80 °C for further analysis. After normalizing the concentrations of the collected medium in each condition to the number of cells/well, 100 μL of the conditioned medium was applied to Bio-Dot SF Microfiltration Apparatus (Bio-rad) using nitrocellulose membrane. The membranes were blocked using 4% BSA in tris-buffered saline with 0.1% Tween ®® 20 Detergent (TBST) for 1 h at room temperature. The membranes were then incubated with the primary antibody prepared at 1:1000 dilution in TBST supplemented with 2% BSA for 1 h at room temperature, washed with TBST (3×) for 5 min. After washing, membranes were incubated with the secondary antibody prepared at 1:10,000 dilution in 2% BSA/TBST for 1 h, and then washed with TBST (3×) for 5 min. Signals were detected in the presence of SuperSignalTM West Dura Extended Duration Substrate (Thermo Fisher Scientific) using ChemiDocTM MP imaging system (Bio-Rad). Band intensities were quantified using ImageJ software https://imagej.nih.gov.

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.
