Percent recovery of donor cells in BM, spleen, and PB 20 hours after transplantation of purified Sca-1⁺lin⁻ CD62L⁻ or Sca-1⁺lin⁻ CD49e⁺ cells into irradiated or nonirradiated 1°ST mice.

Irradiated or nonirradiated mice received 4 × 10⁴ to 3 × 10⁵ sorted Sca-1⁺lin⁻CD62L⁻ or CD49e⁺ cells, killed 20 hours later, and percent recovery of donor cells in harvested BM, spleen, and PB was calculated as described in “Materials and methods.” Bars represent mean ± SEM recovery of cells in each tissue; n = 11 for irradiated, n = 4 for nonirradiated.
