Zebrafish serves as a valuable model for studying tissue regeneration due to their comprehensive regenerative abilities, particularly in bone tissue. In this study, a Mueller matrix optical coherence tomography (OCT) system was applied to monitor the regenerative processes of zebrafish caudal fins in vivo. The analysis focused on evaluating the thickness of the caudal fin tip and the distribution of internal bone tissue during the regenerative process. Subsequently, the effect of ectoine solution on the regeneration process was observed and discussed. Our findings revealed that the caudal fin blastema did not exhibit phase‐induced polarization characteristics in the Mueller matrix OCT images. Statistical analyses indicated that the caudal fins did not fully regenerate to their original state within 21 days. Furthermore, the results suggested that ectoine solution could enhance tissue regeneration. This approach provides a method for quantifying zebrafish caudal fin regeneration and advances observation techniques for biomedical and clinical applications.

Traditional bulk hydrogels containing antibiotics or metal ions often fall short in effectively treating wound infections due to mechanical limitations, bacterial resistance, and potential cytotoxicity. To address these challenges, an extracellular matrix (ECM)‐inspired antibacterial fibrous hydrogel featuring an anisotropic topological structure is developed that closely mimics the natural ECM environment. A novel antibacterial agent, PHMB‐VAN‐Gd (PVG), is synthesized by reacting polyhexamethylene biguanide (PHMB) with O‐Vanillin (VAN) to form the Schiff base ligand PHMB‐VAN (PV), followed by coordination with gadolinium ions (Gd3⁺). Employing silk fibroin (SF) as the matrix, the PVG complex is incorporated into fibrous hydrogels through electrospinning, generating structures that replicate the fibrous architecture of the ECM. The resulting SF‐PVG fibrous hydrogels exhibited robust antibacterial activity, effectively inhibiting bacterial growth and biofilm formation. Furthermore, the aligned fiber orientation and substantial mechanical strength of these hydrogels facilitated cellular functions, promoting cell attachment and proliferation. This study underscores the significant potential of SF‐PVG hydrogels for wound infection treatment.
