Engraftment frequency of mice to which hESC-derived CD34⁺ or CD133⁺ CD34⁻ cells had been transferred

Cells	Day 7	Day 10	Day 11	Day 14
Experiment 1
CD133+	NT	3/5	NT	0/3
CD34+	NT	2/5	NT	1/3
Experiment 2
CD133+	1/3	NT	2/7	NT
CD34+	1/4	NT	1/2	NT
Experiment 3
CD133+	NT	3/4	NT	NT
CD34+	NT	3/5	NT	NT

Two experiments with SCID-hu mice (experiments 1 and 2) and one experiment with RAG-hu mice (experiment 3) are shown. Those mice found positive for engraftment were determined to have CD45⁺, EGFP⁺ cells at the indicated time points. NT, not tested.
