https://safirsoft.com Study: Glow-in-the-dark worms may shed light on the secrets of regeneration

Fluorescent proteins enable scientists to monitor cells within cells as the worms regenerate. Corals, thanks to similar proteins, can shine in a wide range of colors. According to a new article published in the journal Developmental Cell, scientists at Harvard University have now modified the three-banded tiger worm so that the creature can emit a similar green glow. Their hope is to discover the secrets of reconstruction.

Most animals show some kind of regeneration: for example, regrowth of hair or weaving of a broken bone as new skin grows. But some creatures are able to perform amazing regenerative feats, studying the mechanisms through which they can have important consequences for human aging. For example, if a salamander loses a leg, the limb grows back, while some lizards can pull their tails to distract themselves to escape predators and then grow back. Zebrafish can regenerate a lost or damaged fin and also repair a damaged heart, retina, pancreas, brain or spinal cord. Cut a flat polar worm, mermaid, or anemone in half, and rejuvenate your whole body.

Get there. It is somewhat similar to greasy rice grains, which are so called because of the distinctive cream-colored streaks all over its body. If the tiger worm splits into three parts, each part forms into a full worm within eight weeks or more. These worms are found mainly in the Caribbean, the Bahamas and Bermuda, as well as in Japan, fishermen are greedy, and if they are hungry enough and cannot find any other prey, they can take a few bites from their fellow leopard worms. . . They provide a promising new paradigm for studying regeneration mechanisms. They collected 120 or more worms in Bermuda and transported them to Cambridge. The worms did not immediately adapt to laboratory life: Srivastava and Redin had to determine the correct salinity level for their water and also find an acceptable food source. The worms did not care about the liver that Redin fed his Arctic flatworms, and a few resorted to cannibalism to survive. Eventually, the researchers discovered that tiger worms liked saltwater shrimp (known as sea monkeys), and that these creatures eventually began to grow and reproduce.

Report published in 1960 claims that these worms can regenerate their severed heads, but little scientific research has been done.Early experiments by Redin and Srivastava proved that tiger worms can not only regenerate their heads, but can regenerate almost any part of the body, just like polar flat worms Even if the two are only remotely connected, Srivastava now runs his own laboratory at Harvard University to study reconstruction in tiger worms.
