研究室紹介
Professor Junboum Park's research lab specializes in biomedical and environmental applications of advanced materials, with a focus on stem cell biology, tissue engineering, and environmental remediation. The lab investigates multipotent stem cells from accessible sources like gingival tissue for regenerative medicine, explores mechanisms of cell death in intervertebral disc degeneration, and develops sustainable solutions for environmental pollution—such as heavy metal adsorption using oyster shell powder and the environmental impact of discarded facemasks. Additionally, the lab contributes to nanomaterial synthesis, particularly vertically aligned ZnO nanotubes on graphene for potential electronic and sensing applications.

15BACKGROUND AND OBJECTIVE: The main purpose of this study was to isolate and characterize gingival connective tissue-derived mesenchymal stem cells (GMSCs). The secondary purpose was to present a modified isolation method for the GMSCs. MATERIAL AND METHODS: Collected healthy gingival tissue samples were de-epithelialized and minced into small fragments. The tissues were digested by dispase and collagenase IV for 30 min. The first digested cell suspension was discarded, and then additional digest
Our results suggest that, unlike nucleus pulposus cells, anulus fibrosus cells are Fas Type-I cells, which undergo apoptosis through the death-inducing signaling complex. We also found that apoptosis of intervertebral disc cells can be attenuated by caspase inhibitors.
Single-use disposable facemasks have been used as a preventive measure against the ongoing COVID-19 pandemic. However, many researchers have found evidence that these facemasks are being dumped into lakes, rivers, and open garbage dumps. Facemasks have the potential of releasing microplastic fibers into the environment; a phenomenon that has been poorly investigated. Moreover, microplastic fibers composed of plastics have the potential of affecting the flora and fauna of many ecosystems. In this
Urease is an important virulence factor of pathogenicity of gastric Helicobacter pylori. The inhibition of H. pylori urease by the novel proton pump inhibitor, rabeprazole, was investigated kinetically. It was found to act as an irreversible noncompetitive inhibitor of the enzyme. The inhibitory potency of rabeprazole was dependent on the pH of reaction mixture and its Ki values were 0.14 microM (pH 5.0), 0.34 microM (pH 7.0) and 6.10 microM (pH 8.5). Progressive inactivation of urease by rabepr
