Despite their relevance, no full bibliometric analysis has yet been done in this topic. The goal of this work is to use bibliometric analysis to map the fundamental and emergent areas in therapeutics targeting colon cancer stem cells. To perform bibliometric analysis on colon cancer stem cells (CCSCs) literature, spanning roughly the last 40 years, in order to establish a firm base for future projections by emphasizing the findings of the most notable research. All information pertinent to CCSCs was accessed from Web of Science Core Collection database. In order to identify and analyze the research hotspots and trends related to this topic, Biblioshiny (RStudio) and VOSviewer were utilized to ascertain the countries/regions, institutions, journals, authors, references, and keywords involved. The targeted time span covered 1735 research-, and review articles. The most frequent keywords were “colorectal cancer,” “cancer stem cells,” and “colon cancer,” while the most trending keywords in the last few years were “protein stability,” “spheroid formation,” “ubiquitination,” “exosomes,” “patient-derived organoids,” and “gut microbiota.” Over the past 40 years, there has been a significant advancement in researchers' understanding of colon cancer stem cells. In addition, the cluster map of co-cited literature showed that colon cancer stem cell research has emerged as a research hotspot. It was also anticipated that the main focus of the future efforts appears to involve clinical applications of cell-targeted colon cancer therapy. These results provide researchers with a comprehensive understanding of this field and provide insightful ideas for further research.</div></div>","PeriodicalId":20895,"journal":{"name":"Regenerative Therapy","volume":"29 ","pages":"Pages 19-34"},"PeriodicalIF":3.4,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No group reported cytotoxicity and the best blood compatibility in decellularization with herbal agents was reported. Protein bands are largely conserved in all methods. Higher antibacterial properties were observed in the decellularization technique with ACP.
