1% as demonstrated by S-100 staining and fluorescent microscopy (Fig. 1). To determine the effect of the overexpressed NRG1 on the growth of SCs, we counted the cell numbers and examined cell morphology. After SCs were transfected with NRG1 gene for 72 hr, the cells were clustered together as observed under an inverted microscope. Cells were proliferating significantly and the nucleus was large and bright. The body of the cell was transparent with evenly distributed cytoplasm and good refractivity (Fig. 2). The cell numbers of SCs and NRG1-transfected SCs were counted after culturing for various periods of time, and the data showed that the NRG1-transfected cells proliferated http://en.wikipedia.org/wiki/NK_cells quickly (Fig. 3). These results suggested that expression of NRG1 can facilitate the differentiation and proliferation of glial cells. Fluoroimmunoassay with anti-NRG1 antibody was used to assess the transfection rate of SCs. SCs transfected with NRG1 gene were stained with anti-NRG1 antibody and FTIC-labeled secondary antibody. The nucleus was stained with DAPI. All the cells exhibited blue fluorescence (Fig. 4A) and the NRG1-positive cells exhibited green fluorescence (Fig. 4B). Overlay image showed that the NRG1-positive http://www.selleckchem.com/products/DAPT-GSI-IX.html cells displayed blue�Cgreen overlapped color (Fig. 4C). The blue�Cgreen cells accounted for 57.83% of the total cells, suggesting that the transfection rate of SCs was 57.83%. Because of the low expression level of NRG1 in untransfected SCs, fluoroimmunoassay with anti-NRG1 was negative (Fig. 4D�CF). To understand the effect of NRG1 overexpression on the levels of its receptors, ELISA was used to quantify the concentrations of NRG1, ErbB2, and ErbB4 in cell culture media and cell lysate after culturing for various periods of time. ELISA analysis showed that NRG1 in the supernatant and cell lysate was increased 48 hr after transfection. In addition, NRG1 increased in a time-dependent manner with the maximal concentration was achieved at 72 hr after transfection. Statistical analysis showed that http://www.selleckchem.com/products/Gefitinib.html NRG1 in the supernatant and cell lysate after 72 hr of transfection was significantly higher than that in untransfected cells (P
