Fig. 3From: Hyaluronan coating improves liver engraftment of transplanted human biliary tree stem/progenitor cellsPopulation Doubling (PD) of uncoated versus hyaluronan (HA)-coated human biliary tree stem cells (hBTSCs) at different times in culture. PD was always higher in HA-coated cells as compared with uncoated hBTSCs. Data expressed as mean ± SD for three experiments; *p < 0.05, §p < 0.01Back to article page
