Mexican aphrodisiac is a type of salamander , but it is not much the same as ordinary salamanders.
Most species of salamanders are typical amphibians , which is quite similar to frogs. They live in water when they are young and can board land after experiencing abnormal development. However, the Mexican aphrodisiac is different. They do not need to go through the abnormal development process, and can maintain their childhood status throughout their lives and live in water all the time. The regeneration ability of the Mexican sausage is very powerful. Not only can the cut limbs be regenerated, but even the internal organs of the body can be regenerated, but the most powerful thing is their brain regeneration ability. Even if one piece is cut off, it can still be repaired as before.
For animals, the brain is the center. All thinking comes from the brain, and all memories are stored in the brain. How can such a complex organ be regenerated?
In order to solve the mystery of brain regeneration in Mexican slut, a research team led by Chinese scientists successfully drew a space-time map of brain regeneration for Mexican slut, and published this research result in the journal Science. To solve the mystery of brain regeneration in Mexican slut, we must first figure out which cells play a role in the brain regeneration process, and which cells are dominated by different brain regeneration stages. How can we figure out these problems by
?
If a cell wants to express a gene, it must first transcribe DNA into messenger RNA, and then transport RNA will capture the corresponding amino acid based on the sequence provided by the messenger RNA, and finally combine it to form protein . From this we can see that even if the same cell is expressed in different genes during brain regeneration, the corresponding messenger RNA will be different. Therefore, only by measuring the concentrations of various messenger RNAs at the same time, we can know which cells are actively expressing which genes. During the experiment, the researchers removed part of the left brain of the Mexican Blunt Axolotl and divided the brain regeneration process into 7 different stages and observed it.
Through observation, the researchers found that the brain of the Mexican Blunt Axolotl had been repaired on day 30, but there were still differences in the cell types and undamaged areas in the damaged area. Until day 60, the levels and distribution of various cells in the brain tended to be consistent with the undamaged areas.
Researchers compared the brain slices during the repair of the Mexican axolotl with the brain slices during the early development of the young axolotl. They found that on the 15th day after the injury, the cell distribution and spatial structure in the brain of the Mexican axolotl were highly similar to those of the young axolotl. The observation of
shows that brain damage has brought the neural stem cells of the Mexican Blunt Axolotl back to the early developmental state, so this can be regarded as a restart of the developmental process.
Nature has given Mexican aphrodisiacs a powerful regeneration ability, but it does not give them strong environmental adaptability. You may not imagine that this animal with regeneration superpowers has been listed as a critically endangered species. Their only habitat is Lake Hodgemilco, and the total number is less than 1,000. The reason why we have come to such a situation is closely related to the increasing local water pollution. After all, this kind of salamander must live in the water for the rest of his life.
