Building a Better Meniscus
More on the tissue engineering of cartilage from Medical News Today: "The project aims to develop a tissue-engineered meniscus using tailored three-dimensional scaffolds and mesenchymal stem cells (precursors of the meniscus). ... The general wear and tear of normal life can cause damage requiring surgery. In fact, in any gathering of people, about 50 percent of the group will have a damaged meniscus and some may not have any meniscus in one or both of their knees. Unlike other body tissues, the meniscus does not repair itself because only a very small part receives blood, which is why surgery is often needed. While most patients quickly recover from a meniscusectomy, long-term issues such as early arthritis of the knee joint are common. ... The holy grail would be to harvest some mesenchymal stem cells from the patient, combine them with the scaffolds and appropriate growth factors and then insert this matrix into the knee so the patient effectively regrows their meniscus."
