Scientists have reported advances in growing functional biological tissues in the laboratory, including bone, muscle and cartilage, using stem cells and engineered scaffolds. The work demonstrates that mesenchymal stem cells derived from bone marrow can be directed to form multiple tissue types under controlled conditions.
In the reported research, stem cells were expanded in vitro and placed onto 3D-printed scaffolds designed to provide structural support and shape. These scaffolds allowed the cells to organise into tissue-like structures resembling bone, cartilage, muscle and fat.
The work forms part of ongoing efforts in regenerative medicine to develop laboratory-grown tissues that could potentially be used for repairing or replacing damaged biological structures in the future.
