U.S. scientists study called cadaver or stem cell an important source

Human bone marrow contains mesenchymal stem cells (MSC), which can develop into bone, cartilage, fat, and other types of cells. Mesenchymal stem cells can be transplanted, and what type of cells they grow into depends on where they are injected. For example, mesenchymal stem cells injected into the heart can form healthy new tissues, which is an effective method for treating chronic heart disease. However, this therapy requires a large amount of stem cells, and medical staff may have difficulty obtaining enough stem cells from a living donor. Will the corpse be the answer? After a person dies, most cells in the body will die within two or three days. However, due to the extremely low oxygen content in the living environment of mesenchymal stem cells, Janluca de Hipolito and colleagues at the University of Miami in the United States suspect that such cells will live longer than their counterparts. To investigate the matter, Deipolito and his colleagues kept the finger bones of the two bodies for 5 days. Subsequently, mesenchymal stem cells were extracted from the bone marrow of each phalanx and cultured in vessels. After 5 weeks, Deipolito successfully cultivated stem cells into chondrocytes and fat cells. Earlier this month, he announced the results of his research at the World Stem Cell Summit in West Palm Beach, Florida.

Deipolito said that a living donor can provide a limited amount of bone marrow, but a corpse can become a sufficient source of human cells. Paul Machiarini, a regenerative medicine expert at the Caroline School of Medicine in Sweden, considers the above research to be a big step forward, but he also said that cadaver cells may not be as healthy as they seem. The DNA of these cells may be affected by the death of surrounding tissues and exposure to low temperatures. He said: "We must determine the safety of these cells.
