Specifically, we analyzed many morphological properties, like the expression in the neuron-specific proteins -tubulin III and neurofilament. Then, we focused on the CAergic pathway by evaluating the expression profiles from the major genes involved in CA synthesis and storage as well as the presence of DA and NA upon differentiation. Our outcomes emphasize that the two cell lines tested possess related abilities to differentiate and obtain neuron-like morphology. By far the most evident effects inside the SH-SY5Y cells have been observed in the presence of staurosporine, whilst RA induced the strongest effects inside the BE(two)-M17 cells. There have been some relevant differences in the CAergic pathway among the two cell lines. Undifferentiated SH-SY5Y cells make both NA and DA, however the NAergic phenotype appears to become additional pronounced. The CA concentration is strongly elevated right after staurosporine-induced differentiation as well as the cells grow to be mainly NAergic. Undifferentiated BE(2)-M17 cells produce both NA and DA, but their amounts are drastically higher compared with those created by SH-SY5Y cells and their phenotype is a lot more DAergic. The CA concentration in these cells can also be strongly elevated upon differentiation with staurosporine. Tissue culture reagents have been purchased from Gibco/Life Technologies. Chemical compounds have been obtained from Sigma-Aldrich. Stock solutions of RA had been ready by dissolving the powder in DMSO, and TPA and staurosporine had been dissolved in 100% ethanol. In all of the experiments, the final concentration of ethanol never ever exceeded 0.1% and had no detectable impact on cell growth or differentiation. The SH-SY5Y and BE(two)-M17 cell lines were purchased in the Cell Factory-IST Genova and LGC requirements, respectively. Undifferentiated human neuroblastoma SH-SY5Y and BE(two)-M17 cells had been maintained in a 1:1 mixture of Ham's F12 and Dulbecco's Modified Eagle's Medium supplemented with 10% fetal bovine serum and grown within the presence of 5% CO2 in a humidified incubator at 37. The cell medium was replaced each three days, and also the cells had been sub-cultured as soon as confluence was reached. In all the experiments, the cells have been used at early passages (P1-5 soon after purchase). Variations in morphology involving proliferative and differentiated cells were evaluated by phase contrast light microscopy (Motic AE2000) For cell proliferation analysis, 105 cells had been seeded into 25 cm2 flasks. Twenty-four hours after seeding, differentiation was induced by the addition of TPA, RA or staurosporine at concentrations of 15 nM, ten M or ten nM for SH-SY5Y cells and 30 nM, 5 M or 8 nM for BE (two)-M17 cells, respectively. Fresh media containing the specified inducing agent was offered each and every two days. To determine the rate of cell growth, cells had been harvested immediately after a 0.05% trypsin remedy and quantified working with a hemocytometer. Briefly, about 50 l from the cell suspension was added into the Bker chamber. Cells had been counted in four huge 1 mm2 squares below an inverted phase contrast 214766-78-6 microscope working with a 10X magnification. Then, the typical variety of cells per square was determined. The total variety of cells overlying a 1 mm2 square was in the r
