What are stem cells?

Stem cell science is currently one of the most cutting-edge and cutting-edge sciences in life sciences. It has transformed many human dreams into reality and opened up an epoch-making revolution in life sciences.

Cells are the basic unit of the human body. The root cause of human aging is the aging and apoptosis of cells in the body. It is the decrease in the number and function of cells. In addition, the formation of many diseases and chronic diseases is also related to stem cells.

Stem cells are the original undifferentiated primordial cells of the human body, which can self-divide and proliferate, as well as differentiate into a variety of cells with specific functions. Such primitive cells with "regeneration" and "differentiation" are called "stem cells". Human embryos, placenta, umbilical cord, umbilical cord blood, bone marrow, fat, and peripheral blood have stem cells. All human tissues and organs need to be constantly updated and repaired throughout life. Stem cells are the key role responsible for this major task.

New hope for top repair, anti-aging, medical treatment

Cells are responsible for the daily operations of our body, such as the beating of the heart, thinking of the brain, blood cleansing of the kidney, replacement of the skin, and so on. The unique job of stem cells is to make all other types of cells. Stem cells are the supplier of new cells. When stem cells divide, they will make more stem cells or other types of cells to repair body cells.

For example, skin stem cells can make more skin stem cells, as well as skin cells that have differentiated and have specific functions, such as cells that make melanin and cells that repair epidermis. Stem cells not only repair the exposed skin, but also all the organs of the human body. For example, heart repair, liver repair, etc. "Beauty and anti-aging"! Stem cells have a homing effect. When the number of stem cells is sufficient during the repair process, excess stem cells will undergo apoptosis or become dormant. When the body needs repair, it can wake up at any time to join the repair process.

According to the current technology, most of the stem cell repair process is performed by intravenous infusion, and the stem cells are allowed to judge the needs of the body to perform repairs. The repaired part is often different from the patient's expectations. In order to achieve a more accurate effect, some Body parts can achieve more precise effects through local injection, but not every part can be treated locally, and the results are not guaranteed to be satisfactory! This is also stem cell medicine, and there is still room for effort in the future.

In the future, the goal that advanced medical nations are striving to overcome is to be able to induce stem cells more precisely, to achieve the designated areas where patients expect treatment, and to achieve safer, more obvious and broader therapeutic effects, such as: iPSC for short iPS ( Induced pluripotent stem cell) Chinese translation: Induced pluripotent stem cells, also known as artificially induced pluripotent stem cells, are a type of targeted stem cells with great potential. However, there are still possible long-term risks or sequelae, which need to be observed.
