To solve challenges in bone grafting, tissue engineering strategies are proposed for repairing critical-sized defects. One promising approach is the use of cartilage-mediated bone constructs, mimicking the process of endochondral ossification. This review discusses the recent biomimetic strategies and the importance of different cell types, culture conditions, and biomaterials in promoting successful bone regeneration.
In order to solve the clinical challenges related to bone grafting, several tissue en-gineering (TE) strategies have been proposed to repair critical-sized defects. Generally, the classical TE approaches are designed to promote bone repair via intramembranous ossification. Although promising, strategies that direct the osteogenic differentiation of mesenchymal stem/stromal cells are usually characterized by a lack of functional vascular supply, often resulting in necrotic cores. A less explored alternative is engineering bone constructs through a cartilage-mediated approach, resembling the embryological process of endochondral ossification. The remodeling of an intermediary hypertrophic cartilaginous template triggers vascular invasion and bone tissue deposition. Thus, employing this knowledge can be a promising direction for the next generation of bone TE constructs. This review highlights the most recent biomimetic strategies for applying endochondral ossification in bone TE while discussing the plethora of cell types, culture conditions, and biomaterials essential to promote a successful bone regeneration process.
