Found the key to opening the immortal door?

Scientists at the University of California at Davis (USA) have discovered the genetic mechanism of tissue regeneration in hydrothermal species living in freshwater, this mechanism allows animals to recover the body from a piece of tissue, This is essentially biological immortality.

Stem cells give rise to precursor cells, which are located in the outer layer of tissue and form nerve tissue or turn into glands.

The regeneration of polyps involves the participation of three groups of stem cells, which transform into neural tissues, glands and other organs. The researchers analyzed 25,000 cells isolated from animals to determine which genes are active in each cell.

Scientists used fluorescent probes linked to RNA information, the direct product of gene expression, used to synthesize the corresponding protein. This allows tracking the fate of individual cells.

Biologists found that stem cells give rise to precursor cells, which are located in the outer layer of tissue and form nerve tissue or turn into glands. At the same time, changes in gene expression occur when cells move through the body. This allows creating a development map of 12 different types of neurons and other tissues.

Researchers hope that the results of scientific work will help develop new ways to heal damaged tissues in humans.
