Methods of cryopreservation of stem cells, blood and sperm have been around for a long time. But for many different reasons, not everyone knows it to understand it. Please see the article below to better understand the method as well as how to preserve sperm, how to preserve stem cells

With the actual situation of complicated developments of diseases in Vietnam. The solution using cryopreservation of stem cells, blood and sperm was found. The application of stem cells, blood or sperm has been extensively explored and utilized by many medical researchers

 

 

1.Information on cold storage method
Methods of cryopreservation of stem cells, blood and sperm are currently dominant both at home and abroad. Using heat to preserve will protect the invasion of environmental microorganisms, and limit the activity of cells. Helps blood cells, stem cells or sperm to hibernate.

2. What is stem cell preservation?
Stem cells are expected to be one of the solutions that can cure many incurable diseases such as cancer, cardiovascular, endocrine, etc., so how to take them safely, and how to best preserve them?

It is a fact that until now, stem cells have not been used much in Vietnam. The success of Vinmec Stem Cell and Gene Technology Research Institute. In the treatment of patients with cerebral palsy, it has created a stepping stone for further studies by many other units.

How to preserve stem cells?
Professional medical team will use in combination with specialized machine system to get stem cells. Stem cells after being removed from the host body will be processed by other stages in a completely sterile environment.

The stem cells are then placed in a special bag. It has the ability to withstand the deep cold of Nitrogen in a vacuum environment. They are marked by barcode, sealed 2 times. stored in the storage room. Before putting into -196 0C environment, it will be at -90 0C first. This period lasts about 1.5 hours to avoid heat shock and death of stem cells.

Stem cell preservation costs
One of the places where the most stem cells are found is in the umbilical cord blood. Umbilical cord blood flows through the fetal circulatory system, providing the best nutrition for the baby's development. The storage of blood in the umbilical cord is studied by many researchers. See it as a form of life insurance for your child.

So how much does it cost to get the cord blood back? At Vinmec, the cost is different according to the storage time needs of each customer:

- 1 year term for 1 sample: 5 million.

– Time of 5 years for 1 sample: 15 million.

– 10 years for 1 sample: 29 million.

– Time of 17 years for 1 sample: 55 million.

There are also fees for collection, processing, transportation, etc. Because of the expensive cost of storing blood and stem cells, very few people use them.

3. How to preserve sperm?
Today, infertility is not too strange for many people. Its rise makes many people afraid and have to reserve for themselves the best path for a beautiful future. Many men decide to deposit their sperm and bank it for cryopreservation. So everyone knows all about sperm cryopreservation? Stem cell preservation

How to preserve sperm by freezing?
Using sperm cryopreservation is one of the techniques that use low temperatures for long-term preservation. Often goes through many stages and all must be done, manipulated in a sterile environment.

Before taking sperm, or even blood, stem cells everyone must do a test. To eliminate infectious diseases. If you have an infection, you can't get it. The men were then allowed to masturbate into the treated plastic jar. After that, the remaining steps will be handled by the medical team. Similar to the preservation of blood, stem cells.

4. Liquid nitrogen for blood preservation
Liquid nitrogen is one of the states of nitrogen at very low temperatures. Produced by fractional distillation of liquid air. Liquid nitrogen containers are used in the storage and transportation of frozen concentrates. Application for preserving stem cells, blood, sperm at -196 0C.

The current trend of late marriage is also one of the reasons that many people use cold storage of stem cells and sperm. Giving birth in the late 30s is more risky. In addition, infertility and sexual weakness in men also affect the quality of life.

Modern technology, the application of liquid nitrogen used to preserve blood, sperm, and stem cells will partly help you feel secure. Methods of cryopreservation of stem cells, blood and sperm are increasingly being discovered by scientists. Promises to bring more success in the future.
