Fig. 7. DPPIV activity in liver extracts from DPPIV-host rats transplanted with fetal liver isolates enriched or depleted of CMP-FLEC. Isolates used to prepare extracts for DPPIV activity assays are indicated on the x-axis with letter designations assigned in Table 1 and Fig. 1. Enzymatic activity is shown on the y-axis. Extract grouping is defined in the legend to facilitate comparison of extracts from isolates enriched for or depleted of CMP-FLEC and/or hepatoblasts.
