Abstract
Aimed to enhance the release of calcium ions to promote the cell expansion and growth of HSCs, a controlled gradient of CaO close to the exterior surface is designed in this study by infiltration. To establish a comparison with infiltration, an experiment of direct mixing HA with CaO is also conducted. XRD result revealed that the extra CaO incorporated into HA caused the formation of tetracalcium phosphate (Tetcp), which played a significant part in the formation of a surface precipitate and weight gain of the samples during immersion of the samples in saline. Infiltrated materials that showed less Tetcp formation showed weight loss and less surface precipitation.
