Injection of hASC spheroid-loaded HA-based hydrogel into geriatric rat laryngeal muscle using a laryngoscope. Under live imaging guidance, the hASC spheroid-loaded HA-based hydrogel was injected into the laryngeal muscle of geriatric rats. A Preparation of the injection laryngoscope equipped with a 25G spinal needle syringe containing hASC spheroid-loaded hydrogel. B, C Anesthetized aged SD rats were fixed using a custom-made frame and hASC spheroid-loaded hydrogel was injected into the laryngeal muscle using a stationary laryngoscope
