SK-N-AS cells - I need your opinion. (May/27/2008 )

We just buy SK-N-AS cells from ATCC. I defrost and cultured the cells in DMEM+SFB10%+NEAA (as recommended). 5 days after that, cells are attached and are growing up. There is not evidence of bacteria nor yeast contamination, but they look strange to me. I have never work with this cell, so I don't know them. I look for pictures in the web and paper and I think they looks different. Moreover, some cells (many) looks grainy.

I attached an image with many picture. So, please, give me your opinion. Are they ok?? If not, what is wrong??!!!!!!!
Help!!!

please!! just tell me if they look healty or not. is it posible that grains in the cells like in the first picture are normal??
