Dear Roger:

   The blast cells which appear during acute transformation of CML have 
been charaterized as resembling lymphoblasts (ie. CD10+/CD19+).  At other 
times the bone marrow phenotype can be quite heterogeneous.  In my 
experience you could expect to see a wide variety of myeloid precursors 
and the proportions of each would be variable over time.  I usually 
advised our hematologists against monitoring CML patients since it was 
difficult to make sense of the dysplastic changes evolving.  In an 
individual undergoing blast transformation in the setting of a 
long-standing myelodysplastic disorder I think the flow would be very 
useful since therapeutic decisions may depend on it.  

   As to your questions about culturing cells, I can't offer any advice.  
Good luck.
