Abstract
A new kind of magnetic thermoseed for bone tissue engineering has been synthesized. The materials used are specially designed to restore bone tissue after tumor extirpation, because they exhibit bioactive behavior and the ability to act as thermoseeds for cancer treatment using hyperthermia. The L929 cell line of mouse fibroblasts has been used in a wide biocompatibility study concerning cell proliferation and morphology studies, mitochondrial function determination, lactate dehydrogenase measurement, and flow cytometry studies, including cell cycle analysis, cell size and complexity, and intracellular reactive oxygen species content. The results presented in this work indicate that these bioactive magnetic materials are highly biocompatible and show greater cell response for thermoseeds with a higher magnetic phase content. There were no significant alterations detected in the cell cycle, and the interaction between fibroblasts and the different mixtures did not induce significant apoptosis.
