Spheroids were grown in medium supplemented with methylcellulose (Thermo Fisher Scientific M352-500). To prepare 100 mL of methylcellulose-containing medium, 1.2 g of methylcellulose was autoclaved in a bottle containing a stir bar. One hundred ml of medium was warmed to 37 °C and then added to the methylcellulose. The methylcellulose medium was then shaken vigorously and allowed to dissolve at 4 °C overnight, with stirring. Cells were maintained at 37 °C in a humidified incubator containing 5% CO2. All cell lines (and their derivatives) were confirmed to be mycoplasma-free using the MycoAlert mycoplasma detection kit (Lonza LT07-218) at the beginning and upon completion of all experiments.

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.
