Studying chimerism in cancer provides valuable insights into several critical areas: - Tumor Microenvironment: Different cell lines can influence the tumor microenvironment, potentially affecting cancer growth and response to treatment. - Immune Response: Chimeric states can impact how the immune system recognizes and attacks cancer cells. - Treatment Outcomes: Understanding chimerism can help predict the success of treatments like bone marrow transplantation, which is often used in leukemia and lymphoma cases.
