How Jellyfish Grow New Tentacles In A Few Of Days?
How Jellyfish Grow New Tentacles In A Few Of Days? The Cladonema jellyfish species can regenerate an amputated tentacle in two to three days, but how exactly does it do so? It’s roughly the size of a pinkie nail. Insects and salamanders alike rely on the capacity to develop a blastema, a collection of undifferentiated cells that can grow into the missing appendage and repair damage, in order to regenerate functioning tissue. Jellyfish and other cnidarians, like corals and sea anemones, have significant capacities for regeneration; yet, it is still unclear how they create the essential blastema. According to a Japanese study team, stem-like proliferative cells help generate the blastema by appearing at the site of damage and aggressively expanding and dividing without yet differentiating into specific cell types. The results were released in the peer-reviewed journal PLOS Biology. “Importantly, these stem-like proliferative cells in blastema are different from the resident stem cells lo...
