The embryonic Carcinoma stem cell line (ECSCs;NT2) was cultured in DMEM (Gibco, UK) supplemented with FCS (Gibco) and 2 mM L-glutamine. Cell passage was carried out by treatment with trypsin (Gibco), and cells were seeded in new dishes at a 1:5 ratio. Neural induction of these cells was accomplished in growth medium supplemented with different inducers and factors over a three-month period. Initially, 2×104 cells/cm2 were seeded in adherent tissue culture dishes in the presence of 10 μM RA for a month. The resultant compact neuro epithelial cells were dissociated by trypsin and seeded in a 3:7 ratio in new adherent culture dishes in the presence of 1 μM cytosine arabinosin (Sigma, USA) only for the first week of this period, 10 μM fluorodeoxyuridine (Sigma, USA) and 10 μM uridine for a month. For neural maturation, the apparent cell aggregates were mechanically dissociated by hitting to the side of the tissue culture dish. Dislodged aggregates were seeded in poly-D-lysine (Sigma)-coated dishes in the presence of 1 μM cytosine ara binosin (for the first week) and 10 μM fluorodeoxyuridine (16 (link)).
Cytosine arabinosin
Cytosine arabinosin is a laboratory reagent used in biochemical and molecular biology research. It is a pyrimidine nucleoside analog that inhibits DNA synthesis. The core function of cytosine arabinosin is to serve as a tool for investigating cellular processes and DNA-related mechanisms.

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.
