Repopulation units (RU) were calculated based on the mean T/C ratios listed in Table 1. The number of cells per liver is shown as the mean of 7 or 8 fetuses obtained for each day of gestation, except day 11 of gestation. The mean number of day 11 fetal liver cells was given by 31 fetuses. RU/105 is the number of RU per 1 × 105 cells tested. RU/liver shows the total number of RU per liver.
