| 例句 | An even more striking example of this apparent “overall vision” of multicellular structures is found in primitive flatworms called planarians. Synthetic Morphology Lets Scientists Create New Life-Forms 2023-05-31T04:00:00Z Most flatworms, such as the planarian shown in Figure 1, have a gastrovascular cavity rather than a complete digestive system. Fundamentals of Biology 2015-01-01T00:00:00Z The simple planarians found in freshwater ponds and aquaria are examples. Concepts of Biology 2013-04-25T00:00:00Z The research suggests that cellular guides hidden throughout the planarian body may make it possible for the worm’s newly grown neurons to retrace their steps. A Worm’s Hidden Map for Growing New Eyes 2020-06-29T04:00:00Z If the processes that enable regeneration in planarians after fission and after cutting are indeed the same, future research should determine the mechanisms that compensate for the lack of an injury signal in fissioning tissue. What makes flatworms go to pieces 2019-08-13T04:00:00Z Cut a chunk out of a planarian, and it will regrow exactly those tissues that were removed, neither more nor less. Synthetic Morphology Lets Scientists Create New Life-Forms 2023-05-31T04:00:00Z Flatworms called planarians are even more resilient—able to surge back after losing 90% of their bodies. From stealing genes to regrowing limbs, how life finds a way to survive and thrive 2018-03-01T05:00:00Z Most PCGs are expressed within planarian muscle4; however, how muscle is specified and how different muscle subsets affect regeneration is unknown. Orthogonal muscle fibres have different instructive roles in planarian regeneration 2017-11-21T05:00:00Z The flatworms known as planarians are neuroscience darlings. Flatworms Recall Familiar Environs, Even after Losing Their Heads 2013-09-21T12:15:00.747Z “This is a fantastic advert for our field,” says Aziz Aboobaker, a biologist who studies planarian worms at the University of Oxford, UK, but was not involved in any of the studies. How to Regrow a Head 2013-07-25T13:45:00.830Z Even a small part of a planarian can regenerate into a full worm with the typical shape and proportions. Synthetic Morphology Lets Scientists Create New Life-Forms 2023-05-31T04:00:00Z Will humans regenerate as well as the planarians? How to Grow a New Head 2013-07-24T19:05:00Z In planarians, positional information has been identified from study of phenotypes caused by RNA interference in which the wrong tissues are regenerated. Orthogonal muscle fibres have different instructive roles in planarian regeneration 2017-11-21T05:00:00Z So the researchers introduced planarians to a textured petri dish and allowed them to get acquainted with their environs. Flatworms Recall Familiar Environs, Even after Losing Their Heads 2013-09-21T12:15:00.747Z Wnt genes occur in all animals, but the studies looked at their roles in planarian flatworms. How to Regrow a Head 2013-07-25T13:45:00.830Z When he and his colleagues manipulated pieces of planarians to alter their bioelectric state, the regenerating cells produced unexpected anatomies—for example, worms with a head at each end. Synthetic Morphology Lets Scientists Create New Life-Forms 2023-05-31T04:00:00Z The worms in question are known as planarians. How to Grow a New Head 2013-07-24T19:05:00Z Cell death and tissue remodeling in planarian regeneration. Orthogonal muscle fibres have different instructive roles in planarian regeneration 2017-11-21T05:00:00Z In the 1950s and 1960s McConnell performed similar tests on planarians—going as far as to feed bits of trained worms to their untrained brethren in an effort to transfer molecules of memory. Flatworms Recall Familiar Environs, Even after Losing Their Heads 2013-09-21T12:15:00.747Z These are planarian worms, and though not of prepossessing appearance generally, are extremely interesting animals to study. Country Walks of a Naturalist with His Children Quite the reverse case presents itself in certain planarians. At the Deathbed of Darwinism A Series of Papers The life cycles, accurately known, of monads repeat themselves as accurately as those of rotifers or planarians. Scientific American Supplement, No. 643, April 28, 1888 Novel monoclonal antibodies to study tissue regeneration in planarians. Orthogonal muscle fibres have different instructive roles in planarian regeneration 2017-11-21T05:00:00Z It is now nearly forty years since the presence of chlorophyl in certain species of planarian worms was recognized by Schultze. Scientific American Supplement, No. 324, March 18, 1882 There was a pause while Dredge turned and laid his extinguished pipe carefully between a jar of embryo sea-urchins and a colony of regenerating planarians. Tales of Men and Ghosts Both chemical and histological observations showed the abundant presence of starch in the green cells, and thus these planarians, and presumably also Hydra spongilla, etc., were proved to be truly "vegetating animals."
