Stem cell tourism is the part of the medical tourism industry in which patients travel to obtain stem cell procedures. [108] The United States has had an explosion of "stem cell clinics". [109] Stem cell procedures are highly profitable for clinics. The advertising sounds authoritative but the efficacy and safety of the procedures is unproven.
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.
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.
The Republicans largely oppose embryonic stem cell research in favor of adult stem cell research which has already produced cures and treatments for cancer and paralysis for example, but there are some high-profile exceptions who offer qualified support for some embryonic stem cell research. [5]
Mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells or medicinal signaling cells, are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue).
Stem cell debates have motivated and reinvigorated the anti-abortion movement, whose members are concerned with the rights and status of the human embryo as an early-aged human life. They believe that embryonic stem cell research profits from and violates the sanctity of life and is tantamount to murder. [25]
Unilateral limbal stem cell deficiency (LSCD) is a corneal disease that occurs when there is a shortage of the limbal stem cells that typically regenerate the cornea as needed. This can lead to ...
Hematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [16] [17] [13] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical twin).
