Indocyanine Green-Loaded PLGA Nanoparticles Conjugated with Hyaluronic Acid Improve Target Specificity in Cervical Cancer Tumors

Indocyanine green (ICG) is a promising agent for intraoperative visualization of tumor tissues and sentinel lymph nodes in early-stage gynecological cancer. However, it has some limitations, including a short half-life and poor solubility in aqueous solutions. This study aimed to enhance the efficacy of near-infrared (NIR) fluorescence imaging by overcoming the shortcomings of ICG using a nano-drug delivery system and improve target specificity in cervical cancer. ICG and poly(lactic-co-glycolic acid) (PLGA) conjugated with polyethylenimine (PEI) were assembled to enhance stability. Hyaluronic acid (HA) was coated on PEI-PLGA-ICG nanoparticles to target CD44-positive cancer cells. The manufactured HA-ICG-PLGA nanoparticles (HINPs) were evaluated in vitro and in vivo on cervical cancer cells (SiHa; CD44+) and human dermal cells (ccd986sk; CD44-), respectively, using NIR imaging to compare intracellular uptake and to quantify the fluorescence intensities of cells and tumors. HINPs were confirmed to have a mean size of 200 nm and a zeta-potential of 33 mV using dynamic light scattering. The stability of the HINPs was confirmed at pH 5.0-8.0. Cytotoxicity assays, intracellular uptake assays, and cervical cancer xenograft models revealed that, compared to free ICG, the HINPs had significantly higher internalization by cervical cancer cells than normal cells ( This study demonstrated the successful application of HINPs as nanocarriers for delivering ICG to CD44-positive cervical cancer, with improved efficacy in NIR fluorescence imaging.
