This is particularly relevant in breast cancer, where the global burden of disease is quite high based on prevalence and a relatively high rate of lethality. Predictive tools to select patients who will be responsive to invasive or morbid therapies (radiotherapy, chemotherapy, immunotherapy, and\/or surgery) are relatively lacking. To be clinically relevant, a model must accurately replicate the biology and cellular heterogeneity of the primary tumor. Addressing these requirements and overcoming the limitations of most existing cancer cell lines, which are typically derived from a single clone, we have recently developed conditional reprogramming (CR) technology. The CR technology refers to a co-culture system of primary human normal or tumor cells with irradiated murine fibroblasts in the presence of a Rho-associated kinase inhibitor to allow the primary cells to acquire stem cell properties and the ability to proliferate indefinitely in vitro without any exogenous gene or viral transfection. This innovative approach fulfills many of these needs and offers an alternative that surpasses the deficiencies associated with traditional cancer cell lines. These CR cells (CRCs) can be reprogrammed to maintain a highly proliferative state and reproduce the genomic and histological characteristics of the parental tissue. Therefore, CR technology may be a clinically relevant model to test and predict drug sensitivity, conduct gene profile analysis and xenograft research, and undertake personalized medicine. This review discusses studies that have applied CR technology to conduct breast cancer research.<\/jats:p>","DOI":"10.3390\/cells12192388","type":"journal-article","created":{"date-parts":[[2023,10,1]],"date-time":"2023-10-01T16:58:09Z","timestamp":1696179489000},"page":"2388","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Unlocking Translational Potential: Conditionally Reprogrammed Cells in Advancing Breast Cancer Research"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2026-7442","authenticated-orcid":false,"given":"Danyal","family":"Daneshdoust","sequence":"first","affiliation":[{"name":"Comprehensive Cancer Center, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mingjue","family":"Luo","sequence":"additional","affiliation":[{"name":"Comprehensive Cancer Center, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1325-1696","authenticated-orcid":false,"given":"Zaibo","family":"Li","sequence":"additional","affiliation":[{"name":"Departments of Pathology, Wexner Medical Center, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaokui","family":"Mo","sequence":"additional","affiliation":[{"name":"Department of Biostatics and Bioinformatics, Wexner Medical Center, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4382-9065","authenticated-orcid":false,"given":"Sahar","family":"Alothman","sequence":"additional","affiliation":[{"name":"Departments of Oncology and Medicine, Lombardi Comprehensive Cancer Center, Georgetown University, Washington, DC 20057, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bhaskar","family":"Kallakury","sequence":"additional","affiliation":[{"name":"Departments of Pathology, Lombardi Comprehensive Cancer Center, Center for Cell Reprogramming, Georgetown University, Washington, DC 20057, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Schlegel","sequence":"additional","affiliation":[{"name":"Departments of Pathology, Lombardi Comprehensive Cancer Center, Center for Cell Reprogramming, Georgetown University, Washington, DC 20057, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5413-3675","authenticated-orcid":false,"given":"Junran","family":"Zhang","sequence":"additional","affiliation":[{"name":"Comprehensive Cancer Center, Ohio State University, Columbus, OH 43210, USA"},{"name":"Department of Radiation Oncology, Wexner Medical Center, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deliang","family":"Guo","sequence":"additional","affiliation":[{"name":"Comprehensive Cancer Center, Ohio State University, Columbus, OH 43210, USA"},{"name":"Department of Radiation Oncology, Wexner Medical Center, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3883-0715","authenticated-orcid":false,"given":"Priscilla A.","family":"Furth","sequence":"additional","affiliation":[{"name":"Departments of Oncology and Medicine, Lombardi Comprehensive Cancer Center, Georgetown University, Washington, DC 20057, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9922-9627","authenticated-orcid":false,"given":"Xuefeng","family":"Liu","sequence":"additional","affiliation":[{"name":"Comprehensive Cancer Center, Ohio State University, Columbus, OH 43210, USA"},{"name":"Departments of Pathology, Urology, and Radiation Oncology, Wexner Medical Center, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jenny","family":"Li","sequence":"additional","affiliation":[{"name":"Comprehensive Cancer Center, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,30]]},"reference":[{"key":"ref_1","first-page":"524","article-title":"Breast Cancer Statistics, 2022","volume":"72","author":"Giaquinto","year":"2022","journal-title":"CA: A Cancer J.
