	FACS analysis			CFC assay % GFP§
	%hCD45*	% GFP†	P‡
-cyt	28 ± 14	54 ± 20	.029∥	39 ± 14
+cyt	42 ± 32	91 ± 5	68 ± 15
-cyt Ara-C	23 ± 22	29 ± 8	.028¶	18 ± 13
+cyt Ara-C	7 ± 6	61 ± 22		45 ± 22

All values are expressed as mean ± SD of 2 experiments performed. For -cyt group, n = 4; for +cyt group, n = 4; for -cyt Ara-C group, n = 6; and for +cyt Ara-C group, n = 5.

n indicates number of mice per group.

^*Percentage of human cells in the mouse BM.

^†Percentage of human GFP-expressing cells.

^‡P value calculated by rank sum 2-sided test.

^§Percentage of human GFP-expressing cells, scored by fluorescence microscopy.

^∥-cyt versus +cyt.

^¶-cyt Ara-C versus +cyt Ara-C.
