Outline of Final Research Achievements

This study aimed to develop the specific hydrogel to facilitate HARP phenomenon by which cancer stem cells are rapidly created by reprogramming. pNaSS sodium sulfonate gel was found to have a high ability to induce the HARP phenomenon. pNaSS gel, which functions as a cancer stem cell niche distinct from the previous gel, and a master regulator of transcriptional regulation was identified. Novel cancer stem cell markers were detected in single cell RNA sequencing analysis. Drug screening platform was established. For clinical application, NAC therapy-resistant cells of human pancreatic cancer were successfully established. Drug screening yielded compounds targeting several drug-resistant cells. We would like to further link this platform to clinical applications.

Academic Significance and Societal Importance of the Research Achievements

現在がん治療において、薬剤耐性、再発の原因となるがん幹細胞に対する診断法、治療法はない。本研究において、極めて迅速にがん幹細胞を創出するハイドロゲルを発見したことはがん幹細胞の早期診断法、治療薬の開発に期待できる。学術的には、リプログラミングは山中因子など外来遺伝子を導入することでiPS細胞が誘導されることは再生医療に応用されつつあるが、本研究のようにハイドロゲルの上でがん細胞を数時間培養するだけで、効果的なリプログラミングを誘導するHARP現象のメカニズムを解明することは、マテリアルによるう細胞のエピゲノムを制御するもので、学術的価値が高い。
