What are Stem Cells ?
In Layman’s terms, stem cells are cells that are not fully differentiated. Stem cells contain:
1.Â Self-renewal ability.
2. Has the potential of multi-directional differentiation.
How are Stem Cells Preserved ?
After the stem cells are isolated and cultured from different human tissues, they are tested and identified, and then frozen in a deep cryogenic liquid nitrogen at -196 Celsiusï¼ so that the activity of stem cells can be ensured for a long time, so that it can be used when clinically needed. Stem cell resuscitation is used to transplant the patient back to the disease for the purpose of treating the disease.
How Many types of Stem Cells are There ?
According to the developmental stage classification it can be divided into Embryonic Stem Cells and Adult Stem Cells.
According to the differentiation potential, stem cells can be divided into omnipotent stem cells, pluripotent stem cells, and unipotent stem cells.
Omnipotent Stem Cells: Have the differentiation potential to form intact individuals, such as fertilized eggs or embryonic stem cells.
Pluripotent Stem Cells: Have the potential to differentiate into a variety of cellular tissues, such as mesenchymal stem cells.
Unipotent Stem Cells: Can only differentiate into one or more closely related cell types, hematopoietic stem cells.
What are Mesenchymal Stem Cells ?
Mesenchymal stem cells (MSC) are important members of the large stem cell family and belong to pluripotent stem cells in adult stem cell lines. Originally found in bone marrow, it has attracted more and more attention because of its multi-directional differentiation potential. Hemopoietic support and promotion of stem cells apply implantation, immune regulation, and self- replication.
Later, scientist discovered that the number of mesenchymal stem cells in the umbilical cord tissue of newborns is much higher than the number of mesenchymal stem cells in bone marrow and cord blood. Therefore, umbilical cord mesenchymal stem cells have become the most popular stem cell for medical professionals.
Mesenchymal stem cells still have multi-directional differentiation potential after continuous subculture and cryopreservation, and can be used as an ideal seed cell for tissue damage repair caused by aging and lesions.
Why do you need to Store Stem Cells ?
Stem cells can be used to treat a variety of diseases including blood and immune system diseases, also the nervous system by dividing, differentiating, repairing damaged tissue cells, replacing damaged cells, changing the function of human microenvironment, and stimulating the regeneration function of the body’s own cells through secreted protein factors. Diseases, cardiovascular and cerebrovascular diseases, and tumors are important resource bases for regenerative medicine. The storage of stem cells is not only used for future treatment, but also has a positive effect in many fields.
How Long can Stem Cells Last ?
In theory, stem cells can be stored for a long time without falling below the life of the human body. Medical research has shown that cells stored for more than one hundred years are still active, and the storage history of stem cells is not long. Medically, there is not enough time to confirm how long the stem cells are stored without losing activity, but the cord blood has been stored for 15 years. The success of stem cell transplantation has also found that stem cell resuscitation, which has been in existence for more than 70 years, remains active.
What is the Future of Mesenchymal Stem Cell Therapy ?
The prospect of mesenchymal stem cell therapy from laboratory to clinical application is incomparably bright. Both the output of scientific research and the applications of ongoing clinical trial reflect that the pace of stem cell therapy is getting faster and faster. The case of stem cell technology bringing new life to patients is no longer rare, and news reports of breakthrough progress are not uncommon. According to the data registered on the clinicaltrials.gov website, currently at least 6,377 stem cell clinical trials are in progress around the world. With the output of these clinical trials, stem cells will bring endless potential to humans.
