Purified P7 precursor cells were grown at clonal density in the presence of mitogens but in the absence of TH. Individual cells were followed by time-lapse video recording to determine when two sister cells produced by a cell division next divided. The results are shown as time of next division for sister cell 1/time of next division for sister cell 2 (both in hours).
