In vitro evaluation of samarium (III) oxide as a bone substituting material.
J. Biomed. Mater. Res. A 94(1) , 130-6, (2010) The biocompatibility of natural samarium (III) oxide, which has previously been used for treatment in bone-related diseases was determined as a first step in its evaluation as a bone implant material. Assessment for 28 days using osteoblast-like cells reveale... |
