Figure 1From: Eggshells as natural calcium carbonate source in combination with hyaluronan as beneficial additives for bone graft materials, an in vitro studyRepresentation of cell proliferation at an initial population of 10000 cells/cm2. The cell number was normalized on day 1 to 100%. (ES: eggshell powder; HA: hyaluronan; HAES: eggshell powder and hyaluronan; CC: calcium carbonate).Back to article page
