Figure 6.

Clonal heterogeneity of subclones is preserved through at least five consecutive generations of recloning of slow growing clones derived from single-sorted CD34⁺CD38⁻ fetal liver cells. The average number of cells in multiple clones of categories A, B, and C (see text) is plotted. A single “category C” clone (dotted line and *) was recloned when 100–200 cells were present and this was repeated for subsequent category C subclones that were produced from a single initial clone.
