With a plastic syringe, it is possible to extract a sample of planaria,... Planarian Regeneration: Its End Is Its Beginning - ScienceDirect An unlikely model animal, the planarian Schmidtea mediterranea, is proving valuable in this endeavor. In 1901, Thomas Hunt Morgan wrote: "The fact that the process of regeneration is useful to the organism cannot be made to account for its existence in the organism" (Morgan, 1901). Planarian Regeneration - iBiology
Though uninvestigated, the structures of these glycans may play a role in planarian regeneration. Whole-organism MALDI-MS analysis of N-linked oligosaccharides from the planarian Schmidtea mediterranea were found to contain multiple isomeric high mannose and paucimannose structures with unusual mono-, di- and poly-galactosylated (n=3-5) core ...

Planarian regenerative capabilities fascinated scientific community since early 1800, including high-standing scientists such as J.T. Morgan and C. M. Child. Today, it is known that planarian regeneration is due to the presence of a wide population of stem cells, the so-called neoblasts.
(The green arrow points to the fully grown part of the arm. The white portion indicated by the red arrow is the regenerating portion.) Regeneration of tissue has been studied from as early as the 1800's since biologists started splitting Planarians (Morgan 1901) and has remained a topic of much interest since. Urban regeneration - it's still about creating places where ... The benefits of urban regeneration are well known. When done well, it sees run-down areas revitalised and creates vibrant spaces that people want to live and work in. For Singapore, a place where people want to be is crucial to the nation's ambition to be a smart, green city that continues to attract talent. Identification of multiple isomeric core chitobiose-modified ... Though uninvestigated, the structures of these glycans may play a role in planarian regeneration.

Regeneration: what does it mean and how does it work ...
Morgan published at least 11 papers on planarian regeneration, and a book on the topic of regeneration (1901)." The amazing regenerative abilities of flatworms have been the subject of scientific interest since the end of the 18 th century, but much of the observational work done in the early days of the field was forgotten. Planaria Genome Loaded with Design Evidence - icr.org The planaria, a type of flatworm, has an amazing capacity to regenerate a new body from just fragments of tissue. Its genome has just been sequenced. The surprising result is a completely unexpected evolutionary conundrum.
Regeneration in planarians is possible due to the presence of neoblasts; undifferentiated cells found throughout the planarian body. When a cut is made, wound healing and proliferation of neoblasts are responsible for the regeneration of a new body parts. In animals, including humans, lipids called prostaglandins play an important role in tissue... Planarian regeneration in space: Persistent anatomical ... Planarian flatworms were moved to the International Space Station for 5 weeks, immediately after removing their heads and tails. A control group in spring water remained on Earth. No manipulation of the planaria occurred while they were in orbit, and space‐exposed worms were returned to our laboratory for analysis. Regeneration and Germ Cell Development in Planarians | HHMI.org
