Stem-cell therapy uses stem cells to treat or prevent a disease or condition. [1] As of 2024, the only FDA-approved therapy using stem cells is hematopoietic stem cell transplantation. [2] [3] This usually takes the form of a bone marrow or peripheral blood stem cell transplantation, but the cells can also be derived from umbilical cord blood.
As such, in recent times, cell therapy has been recognized as an important field in the treatment of human disease, [7] and investigations are ongoing in articular cartilage, [8] brain tissue, [9] [10] spine, [11] heart, [12] cancers, [13] etc. As a consequence cell therapy as a strategy has been attracting significant investments by commercial ...
In some cases, the adenovirus will insert the new gene into a cell. If the treatment is successful, the new gene will make a functional protein to treat a disease. In order to replicate, viruses introduce their genetic material into the host cell, tricking the host's cellular machinery into using it as blueprints for viral proteins.
Gene therapy has emerged as a promising field in medical science, aiming to address and treat various genetic diseases by modifying human genes. The process involves the introduction of genetic material into a patient's cells, with the primary goal of repairing or correcting malfunctioning genes that contribute to hereditary illnesses. This ...
Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system.Immunotherapy is designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies.
An attractive feature of human iPS cells is the ability to derive them from adult patients to study the cellular basis of human disease. Since iPS cells are self-renewing and pluripotent, they represent a theoretically unlimited source of patient-derived cells which can be turned into any type of cell in the body.
Examples include the injection of stem cells or progenitor cells obtained through directed differentiation (cell therapies); the induction of regeneration by biologically active molecules administered alone or as a secretion by infused cells (immunomodulation therapy); and transplantation of in vitro grown organs and tissues (tissue engineering).
A stem cell possesses two properties: . Self-renewal is the ability to go through numerous cycles of cell division while still maintaining its undifferentiated state. Stem cells can replicate several times and can result in the formation of two stem cells, one stem cell more differentiated than the other, or two differentiated cells.
