A new study has revealed a technology how to cover biodegradable implants with a human skeleton similar mineral. Bone tissue regeneration, one of the issues of tissue engineering, is a research area for Dmitry Gorin and his international colleagues, a leading research fellow at the RASA Center in Tomsk Polytechnic University. The scientists have developed a new vaterite-based coating for nanofiber scaffold to grow bone tissue cells in a shorter time.
