Novel Approach for Refractive Index Matching in Calcified Tissues

Tissue-clearing techniques have become indispensable in biomedical research, especially for three-dimensional (3D) imaging. These techniques enable the visualization of complex biological structures by rendering tissues transparent while preserving their structural integrity. Calcified tissues, such as bone and cartilage, pose a unique challenge in imaging studies due to their inherent opacity and rigidity. In this work, we introduce a novel modification to the BABB clearing protocol aimed at enhancing the clearing efficacy specifically for calcified tissues. Through this work, we provide an enhanced tissue-clearing method that addresses the specific challenges associated with calcified tissues. This advancement has the potential to facilitate more precise and comprehensive studies in fields such as developmental biology, orthopedics, and regenerative medicine.
