Fig. 7. LI difference between the KGF-treated groups and the saline-treated groups for the influx and efflux, in the different windows in the cell positions in the crypt and for the entire crypt as described for Fig. 1 . The two left hand bars, the influx (BrdUrd-only LI); the two right hand bars, the efflux (3HdThd-only LI). Solid bars, results for 9-a.m./6-day experimental protocol; stippled bars, results for 9-p.m./6-day experimental protocol.
