[0002] Stem cells are a type of multipotent cells with the ability to self-replicate. Under certain conditions, they can differentiate into multiple functional cells. According to the developmental stage of stem cells, they are divided into embryonic stem cells and adult stem cells. According to the developmental potential of stem cells, they are divided into three categories: totipotent stem cells, pluripotent stem cells and unipotent stem cells. Stem cells are a type of immature, underdifferentiated cell that has the potential to regenerate various tissues, organs and the human body. They are called "universal cells" in the medical field.

[0003] Stem cells are usually transported in low-temperature refrigerators, but existing refrigerators will pile up stem cells in the refrigerator during use, which makes it easy to mix up stem cells from different patients. At the same time, during transportation, the stem cells cannot be fixed inside the box, which easily causes the stem cells to be inverted in the refrigerator, making it difficult to take them out. Therefore, a portable ultra-low temperature stem cell transport box is proposed to address the above problems. Utility Model Content
