Cell therapy involves transferring specific cell types into a person to address or prevent disease. Each cell type has genetic instructions determining its function and behavior. Stem cells serve as the foundation of all organs and tissues and can develop into various cell types. When disease disrupts the function of these cells, as seen in cancer, cell therapy can help by introducing healthy, functioning cells to restore balance.
Medical professionals can modify various cell types for therapeutic use in treating disorders such as blood cancers, lymphatic cancers, and plasma cell disorders. Cell therapy uses cells include “autologous” (sourced from the patient) or “allogeneic” (from a donor). Often, patients undergo conditioning pretreatment to suppress immune activity, which increases the likelihood of successful treatment.
The cells used depend on the disease and the intended treatment effect. Blood-forming stem cells (hematopoietic or HSCs) can differentiate into any blood cell needed. Immune cells can recognize and eliminate cancer cells, while mesenchymal stem cells, the most versatile stem cell type, support tissue repair based on specific needs.
Though cell therapy presents the potential for treating severe diseases, challenges remain, particularly in finding matching donors, similar to organ transplant limitations. Accuracy in directing modified cells to the correct tissues at the right volume and duration is critical. Additionally, immune suppression poses challenges, often requiring chemotherapy or other conditioning regimens to prevent an adverse immune response.
