Human dermal fibroblasts (HDFa) (Gibco, USA), were grown in DMEM:F12 (1:1) + Glutamax (Gibco, USA) culture medium, supplemented with 10% FBS (Biosera, GB) and 100 I.U./mL of penicillin and 0.1 mg/mL of streptomycin (Biosera, GB). Normal human astrocytes (NHA) (ScienCell, Carlsbad, CA, USA), were cultivated in Astrocyte Media (ScienCell, USA) supplemented with 2% FBS (ScienCell, USA), 1% AGS (100×; ScienCell, USA) and 100 I.U./mL of penicillin and 0.1 mg/mL of streptomycin (Biosera, GB).
The other two cell lines represented tumor cell types. Human neuroblastoma cell line (SH-SY5Y) (ECACC, UK), was cultivated in DMEM:F12 (1:1) + Glutamax (Gibco, USA), supplemented with 10% FBS (Biosera, GB) and 100 I.U./mL of penicillin and 0.1 mg/mL of streptomycin (Biosera, GB). Human glioblastoma cell line (T98G) (ECACC, UK), was cultivated in DMEM high glucose medium (Sigma-Aldrich, USA), supplemented with 10% FBS (Biosera, GB) and 100 I.U./mL of penicillin and 0.1 mg/mL of streptomycin (Biosera, GB).

The HepG2 human hepatoma cell line was purchased from the European Collection of Cell Cultures (Salisbury, UK). Cells were grown in DMEM low glucose medium (Biosera) supplemented with antibiotics (100 U/mL penicillin, 100 mg/mL streptomycin), 10% FBS, and 2 mM l-glutamine. Cultures were kept in an incubator at 37 °C in a water-saturated atmosphere of air containing 5% CO2. Stabilized cells (12−35th passage) were split into microtitration plates and used for further experiments.
All procedures, such as viability control (each time only cells with viability greater than 95% were used), erythrosine B staining, and light microscopy, were done in standard aseptic conditions. Each experiment for each compound was done three times in an independent triplicate.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cortical
neurons were isolated from 14-day-old embryos of pregnant
C57BL/6JRj mice (Janvier, France). Brains and cortices were dissected,
and the olfactory bulbs and meninges were removed. The cortices cut
into small pieces were dissociated in gentleMACS tube C (Miltenyi
Biotec) using a Neural Tissue Dissociation Kit (P) (Miltenyi Biotec)
according to the manufacturer’s protocol. The dissociation
was carried out using a gentleMACS Dissociator (Miltenyi Biotec).
The dissociated tissue was filtered through 40 μm cell strainers
(BD Biosciences). Neurons were cultured in Neurobasal medium, supplemented
with GlutaMAX 0.5 mM (Gibco), B-27 supplement (Gibco), and antibiotics
[100 U mL–1 penicillin and 100 μg mL–1 streptomycin (Biosera, France)] in 24-well Corning poly-d-lysine BioCoat plates (Corning, MA) at a concentration of 2.5 ×
105 cells/well. The next day, neuronal cultures were treated
with 5-fluoro-2′-deoxyuridine (2 μM FdU, Sigma) and uridine
(2 μM U, Sigma) to suppress the proliferation of other nonneuronal
cells potentially occurring in the cell culture. Every 3rd day, half
of the medium was replaced with fresh medium. Cortical neurons were
cultured for 12 days and then used for experiments.66 (link)

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.
