    Bone fracture incidence reached 178 million globally in 2019, with 5%-10% of patients experiencing complications related to healing.

  • 2

    Standard treatments for non-healing fractures include autografts and allografts, which have disadvantages like infection and donor site morbidity.

  • 3

    Bone tissue engineering aims to create biomimetic materials that replicate the properties of bone grafts using various scaffold materials.

  • 4

    This study developed a methodology for scaffold-free bone tissue engineering using large MSC spheroids containing 5 × 10^5 cells each.

    Spheroids were differentiated in chondrogenic and osteogenic media to promote mineralization and were fused to create larger bone constructs.
