Sentences with phrase «tadpole eye»

Not exact matches

The research team found that when it increased levels of E-NTPDase2 in tadpole embryos that consisted of only eight cells, they could cause parts of the eye to form not only on the heads of the amphibians, but also in tissues in other parts of their bodies, including their tails.

And in related experiments, he made tadpoles grow eyes on their stomachs by changing the electrical properties of cells to mimic those associated with eye formation.

Their transformation from egg to tadpole to adult is rapid, and it's visible to the naked eye.

Because changing the light's color couldn't indicate whether the tadpoles» transplanted eyes were functional, the researchers turned to a more sophisticated experiment.

This tadpole has no eyes in its head, but it can see just fine out of the one transplanted onto its tail (arrow).

In these tadpoles, the eyes» axons almost universally connected with either the spinal cord or the gut.

Only tadpoles whose transplanted eyes formed connections with their spinal cord managed to learn; eyes that instead connected to the gut were apparently useless.

In contrast, about 10 % of tadpoles with transplanted eyes were able to learn to avoid the red side of the petri dish, compared with about 40 % of the tadpoles with intact eyes.

The blind tadpoles with no eyes still reacted when the light changed.

The study's lead author, Michael Levin, and his colleague Douglas Blackiston took tadpoles of the African clawed frog (Xenopus laevis) whose eyes had been surgically removed and transplanted «donor» eyeballs — one per tadpole — along various points on the back.

Inside the slowly spinning tube, the big eyes of a red - eyed tree frog tadpole stare back.

The reflex is eye movement that keeps a tadpole's gaze fixed on an object while its head moves, keeping its field of vision in focus.

The technique sheds light (literally) on how transplanted tissue interacts with the nervous system — only the tadpoles whose transplanted eyes connected to their spinal cord, rather than their gut, seemed to be able to see.

Despite the remarkable ability of EFTF - expressing pluripotent cells to form eye - like structures on the tadpole flank, it was not possible to record ERGs because of the small size of the induced flank eyes (flank eye volume: 0.007 ± 0.003 mm3; control eye volume: 0.021 ± 0.002 mm3, at stage 41, N = 5).

To determine if mitotic cells were present in the periphery of flank eyes, tadpoles were briefly placed in a solution containing 5 - bromo -2-deoxyuridine (BrdU).

Researchers removed an eye from one tadpole's head and attached it to the skin of another.

When tested, tadpoles used their induced eyes to detect light and to engage in a vision - based behavior.

However, when forced to express the eye field transcription factor (EFTF) genes, the cells differentiate into all seven retinal cell classes and eventually organize themselves into a functioning eye that can detect light and guide tadpoles in a vision - based behavior.

(C) Whole tadpole bright field image overlayed with fluorescent image, showing flank eye (yellow box) on top of gut (dashed line).

Adjusting electric charges in that second tadpole's cells helped its new, third eye connect to its new body.

For their latest study, they removed the left eye from one tadpole and attached it near the tail of another tadpole.

Studies from the Tseng lab showed that tadpoles successfully repair their complex eye after injury or loss.

They studied the characteristics of different frog species throughout the world (Lucy's personal favorite is the red - eyed tree frog), they got an up - close - and - personal view of the life cycle of a frog by caring for an aquarium full of tadpoles, and they wove their study of frogs into a wide variety of reading, writing, and art activities.

Many don budding crystals painted bright blue or a slimy green, another «cup» whose interior is painted with squiggly, eye - ball tadpoles, is filled with black painted fingers covered in tiny bugs.
