The proliferative fate of individual Sca-1⁺c-kit⁺Lin⁻ bone marrow cells from young B6 mice.

A total of 120 individual cells were analyzed for CAFC potential, of which 29 (here shown) started to proliferate within a period of 50 days. Black bars indicate the timepoints at which cobblestone areas were detected. Clone numbers refer to the address of wells in which cell growth was observed.
