Crayfish Can Turn Ordinary Blood Cells Into Neurons

Whatever you go on to call them — crawfish , crawfish , mudbugs — crayfish are pretty tasty . They also have a pretty noteworthy power toregenerate neuron from lineage cellular telephone . Understanding brain regeneration in these little crustacean might one day help us interpret how it could work on in humans .

This find that a creature that can continually make new neurons is startling and exciting . In our human brains , raw nerve cell will sometimes grow but only from stalk cellphone . And we can sometimes even turn mature cell into stem cell through a very specific and contrived process in a research lab . In crayfish , however , the whole process seems to happen course .

To refill neurons in damage eye stalks and smell lap , crayfish simply take cells from their blood and turn them into neurons . New Scientist explicate :

To do so , they utilise what amount to a “ baby’s room ” for baby neurons , a little clump at the base of the brain called the recess .

In crayfish , blood cell are attracted to the niche . On any given day , there are a hundred or so cells in this field . Each cell will split into two daughter cell , herald to full neurons , both of which migrate out of the recess . Those that are intend to be part of the olfactory organization head to two bunch of nerves in the genius called clusters 9 and 10 . It ’s there that the final degree of produce new smell neurons is nail .

The catch is that langouste are not on the button humans , which is quite obvious when you stare down at a dinner plate full of them . As invertebrates , they do n’t technically have “ blood ” but a fluid called hemolymph that circulates in their dead body . These cell in the hemolymph that turn into neurons , which call hemocytes , are very different from our cerise blood cell or hematocytes , despite the similar spellings . Nevertheless , it ’s one of those cool discoveries that shows the value of enquiry into unsung , little animate being . And maybe someday we ’ll be able-bodied to slip their super powers .
