3D printed bone takes a big step forward

Scientists at Rice University and the University of Maryland have outlined a new proof-of-concept for 3D printing artificial bone tissue, in a new paper published in Acta Biomaterialia. The artificial bone concept uses 3D printed cell scaffolds. These experimental structures are made from a custom mixture of polymer and ceramic material. The end product was designed to closely mimic the...

Chinese scientists discover that stem cell regulator CBX4 may prove an effective target for osteoarthritis treatment

Scientists from the Institute of Biophysics of the Chinese Academy of Sciences, Peking University, and the Institute of Zoology of the Chinese Academy of Sciences have found that a protein named CBX4 acts as a regulator of mesenchymal stem cell cellular aging, and senescence. This research is a first in understanding the depth of CBX4's role in aging,...
