Human genome editing, 3D-printed replacement organs and artificial photosynthesis - the field of bioengineering offers great promise for tackling the major challenges that face our society. But as a new article highlights, these developments provide both opportunities and risks in the short and long term.
Stem cell therapy has great potential for curing cartilage damage. However, it has remained unclear whether stem cells are responsible for regeneration or whether they trigger the process. Researchers now have been able to resolve this issue by tracking the effects in a new, natural model.
Researchers have produced the first three-dimensional (3D) map of a molecular 'scaffold' called SgK223, known to play a critical role in the development and spread of aggressive breast, colon and pancreatic cancers.
