Hyaluronic acid‐terminated NP particles have previously been show both in vitro and in vivo to successfully colocalize with CD44 expression on ovarian cancer cells.57, 58, 59 These studies demonstrate that HA‐terminated NPs will successfully target and bind CD44 receptors on ovarian cancer cells such as OVCAR8, which expresses high levels of the receptor. The gene discussed is CD44; the disease is ovarian cancer.
