CD34+ cells could be of a particular interest as up to 12% of the CD34+ population in maternal blood are of fetal origin. The aim of this research was to analyze the impact of umbilical cord blood (UCB) CD34+ on MCF-7 and MDA-MB-231 breast cancer cell lines, in order to uncover novel biological mechanisms and suggest novel treatment options for breast cancer. Methods UCB CD34+ cells were obtained from healthy women at full-term delivery. Direct cultures were grown with MCF-7 and MDA-MB-231 cells. Proliferation, migration, invasion, and transcriptomic analysis of breast cancer cells were compared between cultures exposed and non-exposed to UCB CD34+ cells. Interactions between UCB CD34+ and breast cancer cells were analyzed under fluorescent microscopy. Functional analyses were generated with QIAGEN's Ingenuity Pathway Analysis (IPA) and Gene Set Enrichment Analysis (GSEA). Results Direct contact between UCB CD34+ and breast cancer cell lines induced a reduction in the proliferative capacities of MCF-7 and MDA-MB-231 and diminished the migration abilities of MDA-MB-231 cells. In 3D co-culture, UCB CD34+ cells were attracted by tumor spheroids and incorporated into tumor cells. These cell-to-cell interactions were responsible for transcriptome modifications coherent with observed functional modifications. Among the cytokines secreted by UCB CD34+, IFN was identified as a potential upstream regulator responsible for the molecular modifications observed in transcriptomic analysis of MCF-7 breast cancer cells exposed to UCB CD34+ cells, as was IL-17A in MDA-MB-231 cells. Conclusion Direct cell-to-cell contact induced functional modifications in breast cancer cells. Interactions between UCB CD34+ and breast cancer cells could induce cell fusion and signal transmission via cytokines. Further analysis of direct cell-to-cell interactions should be performed at a molecular level to further understand the potential role of fetal CD34+ cells in breast cancer.</p>","PeriodicalId":9717,"journal":{"name":"Cells Tissues Organs","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142495882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional culture methods often fail to simultaneously facilitate critical cell-cell and cell-extracellular matrix (ECM) interactions while providing control over mechanical and biochemical properties.SUMMARYThis review introduces the spheroid-hydrogel integrated biomimetic system (SHIBS), a groundbreaking approach that synergistically combines spheroid culture with tailored hydrogel technologies. SHIBS uniquely bridges the gap between traditional culture methods and physiological conditions by offering unprecedented control over both cellular interactions and environmental properties. We explore how SHIBS is revolutionizing fields ranging from drug discovery and disease modeling to regenerative medicine and basic biological research. The review discusses current challenges in SHIBS technology, including reproducibility, scalability, and high-resolution imaging, and outlines ongoing research addressing these issues. Furthermore, we envision the future evolution of SHIBS into more sophisticated organoid-hydrogel integrated biomimetic systems (OHIBS) and its integration with cutting-edge technologies such as microfluidics, 3D bioprinting, and artificial intelligence.KEY MESSAGESSHIBS represents a paradigm shift in 3D cell culture technology, offering a unique solution to recreate complex in vivo environments. Its potential to accelerate the development of personalized therapies across various biomedical fields is significant. While challenges persist, the ongoing advancements in SHIBS technology promise to overcome current limitations, paving the way for more accurate and reliable in vitro models.
