When blood supply is insufficient in a certain part of the human body, a condition called ischemia will be caused.After that, if the blood flow is restored, it is called reperfusion. Although this process is crucial for tissue repair, it can cause considerable damage, called ischemia and reperfusion injury (IR damage).This condition may lead to myocardial infarction, stroke, acute renal injury and other diseases, and increase mortality.
After acute ischemia, the oxygen supply and metabolites of tissue are affected, which may trigger a series of biochemical reactions and further aggravate tissue damage.
Studies have shown that the effects of ischemia and reperfusion on various muscle tissues are still unclear, but similar to those in the heart and kidney tissues, IR injuries are likely to lead to tissue fibrosis.Depending on the situation and extent, ischemia-reperfusion can lead to persistent tissue damage.Therefore, how to effectively reduce IR damage has become an important topic in medical research.
During ischemia, the cell decomposition products in the tissues gradually accumulate, and once blood flow is restored, these products enter the systemic circulation, which may cause damage to other organs, especially the kidneys and liver.This process causes the large release of products metabolized by cellular such as lactic acid and myoglobin, which can cause potential burden on the whole body.
Poor cell metabolism will lead to lactic acid production and will continue to affect the surviving tissue.
Although most of the current studies focus on the responses of fibroblasts and leukocytes to IR damage, there is a growing evidence that stem cells have potential benefits for the recovery of ischemia-reperfusion injury.Mesenchymal stem cells, in particular, show the ability to promote tissue repair in different disease conditions.
These stem cells not only induce tissue regeneration, but also promote repair of damaged muscles.The study found that stem cells move to damaged muscles after motor injury, a process that may be related to early responses after stem cells are damaged.
For clinical applications, the rise of stem cell therapy will likely become a new treatment method.With the development of animal models, researchers were able to explore the specific role of stem cells in IR damage and their mechanisms.This may open up new therapeutic avenues, especially in the regeneration and repair of muscle tissue.
The regeneration characteristics of stem cells provide us with new ideas and hope for dealing with ischemia and reperfusion injuries.
Although the current research on stem cells in ischemia-reperfusion injury is still in its infancy, several preliminary results have shown their positive therapeutic potential.With the advancement of science, more targeted therapies are expected to be introduced in the future to improve the prognosis of patients.
Now, we have to think about whether stem cell technology in the future can truly change the treatment pattern of patients with ischemia and reperfusion injury?
