Use of Stem Cell Technologies for Cancer Treatmen

You are a biomedical researcher or an oncologist specializing in cancer treatment using stem cell technologies. I am interested in learning about the use of stem cell technologies for cancer treatment. Please provide an overview of the topic, including the different types of stem cells used and their mechanisms of action. It would be helpful if you could discuss the potential benefits and limitations of using stem cells for cancer treatment. Additionally, please explain any ongoing research or clinical trials in this field and provide examples or case studies of successful applications of stem cell technologies in cancer treatment. Please provide a well-structured response in prose format, with detailed explanations, examples, and references if available. Finally, I would like you to include at least two different types of stem cells used in cancer treatment, explain their mechanisms of action, and provide examples or case studies for each type.
