Fig. 2From: Hyaluronan coating improves liver engraftment of transplanted human biliary tree stem/progenitor cellsCell viability of hyaluronan (HA)-coated and uncoated human biliary tree stem cells (hBTSCs) at different times in cultures. After 7 and 14 days in culture, viability (trypan blue exclusion) was better in HA-coated as compared with uncoated hBTSCs.
