Chengdu Science and Technology Activity Week ｜ Stem cell technology walks into the people's life children to experience liquid nitrogen experiments on the spot

Cover reporter Zhou Jiayi

On the morning of July 9th, the Chengdu Science and Technology Activity Week in 2022 was held at the Chengdu Giant Panda Breeding Research Base. The theme of this current Science and Technology Week is "Entering the Science and Technology You and I".

According to reports, the Chengdu Science and Technology Week activities were held throughout the city from July 8th to 14th. The current Science and Technology Week is divided into two major sections of online activities and offline activities. Offline activities include launching rituals, theme exhibitions, and exhibitions. Interactive experience activities, series of supporting activities during the science and technology activity week, municipal departments and district (cities) and county key activities. Online activities include the popular science base VR cloud tour, cloud science popularization activities, and excellent popular science work display. This year's Science and Technology Week mainly shows the major scientific and technological innovation achievements, major popular science resources and results of Sichuan Province and Chengdu, highlighting the achievements of scientific and technological innovation to support the high -quality development of the economy and the improvement of the quality of the people's lives of the people's lives.

Stem cell technology is not far away from the people's life

At the event site, Sichuan New Life Stem Cell Technology Co., Ltd. brought the "Little Doctoral Stem Cell Laboratory" popular science project. This popular science project was restored to laboratory scenes through multimedia and other multimedia methods such as LED screen video live broadcast, allowing citizens From wearing biological isolation clothes to liquid nitrogen experiments, to electron microscope to observe a series of working links, to understand the scientific knowledge of stem cell -related scientific knowledge. Certificate.

According to reports, stem cells are seed cells with self -replication ability and multi -directional differentiation potential, which are called "universal cells" by the medical community. Stem cells and their differentiated products provide new ways to effectively repair important human tissue organs and cure cardiovascular disease, metabolic diseases, nervous diseases, blood system diseases, autoimmune diseases and other malignant diseases. Regenerative medical research is expected to become the third way of treatment of drug treatment and surgical treatment. It has become one of the most important fields of developed western countries in the forefront of life sciences. It is the focus of world attention and research.

"Actually, stem cell technology is not far away from our ordinary people." Sichuan New Life Stem Cell Popular Science Education Center staff said, "For example, the umbilical cord blood stem cells that are well known can be used for leukemia, Mediterranean anemia, and regenerative disorder anemia 11. The treatment of large categories of blood and immune system diseases; in addition, umbilical cord stem cells, placental stem cells, and deciduous stem cells are also closely related to the health of the people. "In oral diseases, the use of deciduous stem cells to assist dental pulp and alveolar bone regeneration. It is believed that future deciduous stem cells can be used for clinical treatment and improves the quality of life of ordinary people.

So, how is this precious biological resources be preserved for a long time?

Regarding this issue, at the event, popular science staff put a balloon and a rose in liquid nitrogen. The balloon became smaller due to thermal expansion and contraction. The rose was instantly "frozen". "Fragment", this is a simple liquid nitrogen experiment.

According to reports, stem cells have very high requirements for the storage temperature and storage environment. Only in the state of deep and low temperature freezing can the cells be in a "dormant state", all enzymes in the cells are suppressed, and metabolism is completely stopped to freeze for a long time.

"Stem cell frozen is a systematic engineering that seems simple but very technical." The staff said that before the stem cells were put into liquid nitrogen tanks, in order to prevent stem cells from being damaged in the cooling process or low temperature environment, it is necessary to need to be damaged. Add frozen survive protective agents to stem cells before cooling, and during the cooling process, professional cooling equipment uses professional cooling equipment to achieve slowly slow down to ensure the activity of stem cells.

You can visit for free from the stem cell science popularization base

If you still want to know the "secrets" of stem cells, don't miss the science education base of Sichuan New Life Stem Cell on the 15th of Jinquan Road.

It is understood that the construction of the science popularization base is one of the goals of the Municipal Party Committee and Municipal Government for the people's livelihood project for private affairs. measure. In order to improve the public's awareness of stem cell technology and industry, Chengdu Science and Technology Bureau, the Propaganda Department of the Chengdu Municipal Committee of the Communist Party of China, and Chengdu Science and Technology Association are designated in Sichuan New Life Stem Cell Technology Co., Ltd. "".

The popular science base is open to citizens or primary and secondary school groups all year round. Citizens only need to dial 028-87510505-8002 to make an early appointment.
