Hip replacement. Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi/semi (half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some ...
Stem-cell therapy uses stem cells to treat or prevent a disease or condition. As of 2016, the only established therapy using stem cells is hematopoietic stem cell transplantation. This usually takes the form of a bone marrow transplantation, but the cells can also be derived from umbilical cord blood.
Alternative approaches allow for the use of autologous stem cells, which have not been originally harvested from the patient undergoing treatment. Such approaches need to rely on " cloaking " technology to ensure that the cells are not eliminated from the body once detected as foreign.
Mesenchymal stem cells have the ability to stimulate neuroregeneration by differentiating into neural stem cells in response to inflammation. The neural stem cells can then promote the repair of damaged axons and create replacement cells for the damaged tissue.
Recent research demonstrates that articular cartilage may be able to be repaired via the percutaneous introduction of mesenchymal stem cells (MSC's). Stem cells, as a concept, originated as a theory in the 19th century to potentially allow certain tissues to self-renew. There are five types of stem cells, and MSC's are multi-potent, meaning ...
Regenerative medicine. A colony of human embryonic stem cells. Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". [1] This field holds the promise of engineering damaged tissues and organs by stimulating the body's own repair ...
An advantage to this approach is that a person's own stem cells are used, avoiding tissue rejection by the immune system. Stem cells enable surgeons to grow replacement cartilage, which gives the new tissue greater growth potential.
An advantage to this approach is that a person's own stem cells are used, avoiding transmission of genetic diseases. It is also minimally invasive, minimally painful and has a very short recovery period. This alternative to the current available treatments was shown not to cause cancer in patients who were followed for 3 years after the procedure.
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can change into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. [1] They are found in both embryonic and adult organisms, but they have slightly ...
HSCT may be autologous (the patient's own stem cells are used), syngeneic (stem cells from an identical twin), or allogeneic (stem cells from a donor). It is most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma, leukemia, some types of lymphoma and immune deficiencies.
