Relationship between the number of CD34+cells transplanted and percentage of human CD45+ (□), CD34+ (◊), and immature CD34+CD38− (○) cells detected in SCID mouse BM after 5 weeks. Results show the mean ± SD for 3 mice per data point. For comparison, the numbers of CD45+ cells detected in BM of mice transplanted with graded numbers of unfractionated cells are also shown (▪).
