AI Article Synopsis

  • Osteoarthritis (OA) is a common degenerative disease affecting joint cartilage, and researchers are investigating human amniotic mesenchymal stem cells (hAMSCs) as a therapy for cartilage repair.
  • A new treatment involving a combination of hAMSCs and hyaluronic acid (HA) was tested in rats and showed significant cartilage regeneration after 56 days, comparable to healthy cartilage.
  • The study suggests that HA enhances hAMSCs' effectiveness by improving their abilities to differentiate, multiply, and aid in regeneration, indicating a promising direction for OA treatment through straightforward injection therapy.

Article Abstract

Osteoarthritis (OA) is one of the most common refractory degenerative articular cartilage diseases. Human amniotic mesenchymal cells (hAMSCs) have emerged as a promising stem cell source for cartilage repair, and hyaluronic acid (HA) has proven to be a versatile regulator for stem cell transplantation. Herein, an effective and straightforward intra-articular injection therapy using a cocktail of hAMSCs and HA was developed to treat knee OA in a rat model. The injured cartilage was remarkably regenerated, yielding results comparable to normal cartilage levels after 56 days of treatment. Both hAMSCs and HA were indispensable organic components in this therapy, in which HA could synergistically enhance the effects of hAMSCs on cartilage repair. The regenerative mechanism was attributed to the fact that the addition of HA comprehensively enhances the activities of hAMSCs, including chondrogenic differentiation, proliferation, colonization, and regenerative modulation. This cocktail paves a new avenue for injection therapy to treat OA, holding the potential to realize rapid clinical translation.

Polymer based nanoformulations offer substantial prospects for efficacious chemotherapy delivery. Here, we developed a pH-responsive polymeric nanoparticle based on acidosis-triggered breakdown of boronic ester linkers. A biocompatible hyaluronic acid (HA) matrix served as a substrate for carrying a doxorubicin (DOX) prodrug which also possesses natural affinity for CD44 cells.

With the growing demand for aesthetic enhancements, particularly filler injections for nasolabial folds (NLFs), there is a need for more objective and quantitative assessment methods beyond the traditional subjective scales like the Wrinkle Severity Rating Scale (WSRS). This study introduces a novel evaluation method combining 3-dimensional (3D) imaging and grayscale analysis to objectively assess NLF severity and treatment outcomes. A total of 100 healthy participants (86 females, 14 males; mean age 41.

Reactive oxygen species (ROS) scavenging is a viable approach to promote corneal epithelium wound healing. This study created a single-component hydrogel (HA Gel) with a novel dual-functionalized hyaluronic acid derivative (HA-GA-PBA) containing gallol and phenylboronic acid (PBA) moieties. Both of these moieties were dual-functional.

Photodynamic therapy (PDT) holds an essential role in the therapy of tumors. However, PDT consumes tissue oxygen and diminishes its own efficacy by inducing tumor hypoxia through the HIF-1α/VEGF pathway. Therefore, overcoming the photodynamic exacerbation of tumor hypoxia could reverse tumor microenvironment and enhance PDT.

Background: Among several skin fillers developed in recent decades, hyaluronic acid (HA) is a widely used filler for face contouring and is generally believed to be safe, long-lasting, not immunogenic, and cost-effective. However, early and delayed complications can also occur following HA filler injection. Unfortunately, there have been reports of HA-related bone erosion in the chin area without clear scientific data regarding its existence and incidence.
