Once the child is born, umbilical cord blood hematopoietic stem cells, umbilical cord stem cells, placental stem cells.

But if you miss the delivery, is there any chance?

This may be your last chance.

At the age of 6-7, deciduous teeth contain deciduous stem cells.

More and more parents began to store it.

Wu Zuze, an academician of China Academy of Sciences, once said: "People should keep their teeth from childhood, because these teeth contain precious dental pulp stem cells and can be used for stem cell therapy."

In 2003, researchers first isolated deciduous teeth stem cells.

In 2005, Hiroshima University in Japan established the "Three Scaffolds" of Dental Bank to store and study deciduous tooth stem cells.

Today, deciduous teeth stem cells have become a valuable source of stem cells.

Parents also left this precious resource for their children and the whole family.

Why are deciduous teeth stem cells good?

Its self-renewal and multi-directional differentiation potential can be differentiated into pluripotent stem cells with multi-directional differentiation potential, such as nerve cells, adipocytes, chondrocytes, bone cells, tendon cells, liver cells, cardiac cells, islet β cells and muscle cells. It has broad application prospects in the medical field.

Related research shows that deciduous teeth stem cells have stronger proliferation and differentiation potential than adult dental pulp stem cells and bone marrow mesenchymal stem cells.

As we know, human beings are differentiated from a small embryonic stem cell into various tissues and organs and become a complete person.

Let's open a brain hole. If an organ or tissue has a problem, can we use our own stem cells to solve the problem? Even directly differentiate into a new one?

Well, that's what scientists think and practice.

If it is proved to be feasible, it will be too exciting and even change the whole medical pattern.

So, what's the result?

It can be said that it is promising.

For example, deciduous teeth stem cells are very effective in treating tooth injuries.

A new clinical trial led by Shi Songtao of the University of Pennsylvania and Xuan Kun of China Air Force Medical University (formerly the Fourth Military Medical University) shows that there is a better way for children with this kind of injury: using stem cells extracted from patients' deciduous teeth.

The study was published in the journal of scientific translational medicine.

They implanted cultured deciduous teeth stem cells into injured teeth.

It was found that the implanted stem cells regenerated different components of dental pulp, including dentin, connective tissue and blood vessels. Even make the necrotic roots continue to develop.

The functional regeneration of whole pulp tissue was successfully realized, and nearly 50 patients were treated, with an effective rate of over 95%.

In addition, nerve regeneration, bone regeneration and blood vessel regeneration have been realized, and they have been applied to the research and treatment of liver and lung diseases.

At present, deciduous teeth stem cells have been used to treat pulp regeneration, periodontal regeneration, central nervous system injury, neurodegenerative diseases, corneal regeneration, myocardial infarction, liver fibrosis, rheumatoid arthritis, bone and cartilage regeneration, Duchenne muscular dystrophy, systemic immune diseases, endocrine diseases, acute respiratory distress, autoimmune encephalomyelitis and acute renal failure.

In April, 2020, at the Sichuan Science and Technology Awards Conference, the project "Tooth Regeneration Research Based on Stem Cells" presided by Professor Tian Weidong won the first prize of Sichuan Science and Technology Progress in 20 19.

From the discovery of deciduous teeth stem cells to today, it has been so remarkable in just nearly 20 years.

I believe that in the future, the prospects will be even more impressive. Can be applied to more diseases, and even directly regenerate a liver and kidney. The scenes in science fiction movies have really come true.

Ordinary people, it is most important to seize the opportunity and leave this precious resource.

Because I missed the baby's tooth changing period, I missed the deciduous tooth stem cells.

When children's teeth are loose, they should contact a regular institution as soon as possible, collect deciduous teeth, carry out testing and preparation, and store them in a deep low temperature environment of-196 degrees for a long time to ensure the activity of deciduous teeth stem cells.

Sichuan stem cell bank is registered and approved by Sichuan Development and Reform Commission. It is a comprehensive stem cell bank integrating stem cell resource storage, scientific research and development, and industrial application, and basically realizes the whole industrial chain coverage of stem cell storage, research and application. Technology research and development has passed the management system certification of ISO900 1, ISO 1400 1 and ISO4500 1, and the preparation, storage and distribution of stem cells have passed the certification of AABB. The technical level ranks in the forefront of the world, effectively ensuring the stable operation of the quality and safety system and the ability to continuously provide standardized services to customers.
