Ralph,

You can answer a lot of these qustions by using cell surface
labelling -  see JEM 185 (7) 1337 and refs therein for analysis of
erythroid cells. A few describing myeloid differentiation are listed
below - there are many others:

Kerst, J.M., Slapercortenbach, I.C.M., Vondemborne, A.E.G.K.,
Vanderschoot, C.E. and Vanoers, R.H.J. (1992) Combined measurement of
growth and differentiation in suspension-cultures of purified human
cd34- positive cells enables a detailed analysis of myelopoiesis. Exp.
Hematol. 20, 1188-1193.

Terstappen, L.W.M.M., Buescher, S., Nguyen, M. and Reading, C. (1992)

hematopoietic progenitors assessed by multidimensional flow-cytometry.
