Help, NB4 cells.

[Depto. Biologia Celular]

	I am studying the differentiation of leukemic cells along the 
monocytic lineage using calcitriol as differentiative agent and others 
vitamins as possible stimulating compounds on differentiation. In my work 
I have used HL-60 cells as in vitro culture cells but now I have some 
problems because these cells have changed their response and develop 
expontaneous differentiation in normal culture conditions. Now, I am 
thinking on NB4 cells as a better cell line to study differentiation. I 
have ask some information to cell banks as ATCC and ECA but they don't 
have this cell line. Could anybody tell me if anyone can send me this 
cell line?, I have very gratefull if anyone could send me HL-60 cells 
too. Waiting positive responses and acknowledging in advance.
