Figure 4. Integrated pipeline for tendon organoid development and clinical translation. A conceptual workflow illustrating the progression from in silico
design to therapeutic application. Left, AI-powered platforms integrate multi-modal datasets to guide the design of biomimetic tendon organoids.
Bottom, engineered organoids are implanted into injury sites—such as the Achilles tendon—highlighting the translational path from bench to bedside.
