Progress in clinical application of stem cells at present

Theoretically, stem cells can be used for clinical cell transplantation, treatment of various diseases and construction of artificial tissues or organs. The most suitable diseases are mainly myocardial necrosis caused by ischemia, tissue necrosis diseases such as tumors, degenerative diseases such as Parkinson's syndrome, autoimmune diseases such as insulin-dependent diabetes, etc. Compared with traditional methods, the application of stem cells to treat diseases has many advantages: low toxicity or non-toxicity, effective once; It is not necessary to fully understand the exact mechanism of the disease; There is no risk of spreading diseases: autologous stem cell transplantation can also be used to avoid immune rejection.

Research progress of stem cell medicine

At present, the research of stem cells and regenerative medicine has become the most striking field in natural science. The perfection of its theory and the rapid development of technology will surely produce epoch-making achievements in the fields of disease treatment and biomedicine, which is a major revolution in traditional medical means and medical concepts.

Stem cell therapy has many advantages: low toxicity (or non-toxicity), even if the exact mechanism of disease pathogenesis is not fully understood, it can achieve good therapeutic effect, autologous stem cell transplantation can avoid immune rejection, and it has amazing curative effect on diseases with poor curative effect by traditional treatment methods.

Stem cell transplantation for specific treatable diseases.

(1) Stem cells are used to treat nervous system diseases, such as cerebral palsy, spinal cord injury, motor neuron disease, Parkinson's disease, cerebral hemorrhage, sequelae of cerebral infarction and brain injury. (2) Stem cells treat immune system diseases, such as diabetes, dermatomyositis, myasthenia, vascular diseases, sclerosis, leukemia, etc. (3) Stem cells are used to treat other diseases, such as liver disease, liver cirrhosis and femoral head necrosis.
