Scientists at the Israeli biotechnology company Bonus BioGroup Ltd. have grown human bone from stem cells. Using stem cells taken from fat, they grew two-inch-long sections of fully formed living human bone in about a month, according to British science writer Richard Gray in a June 10 article in The Telegraph. The stem cells are grown into bone on a scaffold inside a “bioreactor”—an automated machine that provides the right conditions to encourage the cells to develop into bone. Researchers at the Technion Institute of Research in Israel used three dimensional scans of damaged bone to build the gel-like scaffold.
When scientists inserted about an inch of this laboratory-grown human bone into the middle section of a rat’s leg bone, it successfully merged with the existing animal bone. Bonus BioGroup officials plan to conduct a first trial on patients later this year.
