Silk protein–stem cell bioink utilized to 3D bioprint cartilage

In an Indian first, researchers from IIT Delhi have combined silk proteins, bone marrow-derived stem cells and certain growth factors in a bioink that produced stable cartilage that lasted for up to six weeks. In a study recently published in Bioprinting, scientists from IIT Delhi and IIT Kanpur (both India) have developed a bioink that supported cell growth to produce cartilage that was stable for up to six weeks. “The silk protein has different amino acids that closely resemble the amino acids present in human tissues. Just like cells are surrounded by proteins inside our body, the cells in the...
