pH-Responsive Modified HAMA Microspheres Regulate the Inflammatory Microenvironment of Intervertebral Discs.

Currently, intervertebral disc (IVD) degeneration is believed to lead to local accumulation of lactic acid in the IVD, a decrease in pH, activation of the inflammatory pathway, and continued destruction of homeostasis of the IVD. To address these issues, the intelligent and accurate release of drugs is particularly important. In this study, acid-sensitive release methacrylated hyaluronic acid (HAMA) microspheres were constructed by using microfluidic technology, which can be used as a targeted drug delivery system for intervertebral disc degeneration (IVDD) through Schiff base chemical bonding on the surface of the microspheres to achieve intelligent drug release.

Synchronized long-term delivery of growth hormone and insulin-like growth factor 1 through poly (lactic-co-glycolic acid) nanoparticles on polycaprolactone scaffolds for enhanced osteochondral regeneration.

The regeneration of osteochondral defects is challenging due to the complex structure of the osteochondral unit. This study aimed to develop a biomimetic scaffold by loading growth hormone (GH) and insulin-like growth factor-1 (IGF-1) into poly (lactic-co-glycolic acid) (PLGA) nanoparticles and incorporating them into polycaprolactone (PCL) scaffolds to promote synchronized osteochondral regeneration. The nanoparticles were successfully immobilized onto PCL scaffolds pre-modified with polydopamine (PDA) to enhance cell adhesion and proliferation.
