Flatworms, but make it high-res. 🧠🪱
This new protocol combines tissue expansion + light-sheet microscopy to reveal planarian neural and muscle anatomy in 3D, at single-cell resolution. #Planaria #Microscopy #DevBio

To find the subject of my PhD in the garden pond at my very Cambridge college, that made my day.
Planaria, genus Schmidtea, swimming near the surface:

“Problem?” asked Jin.
“Tom’s mum doubted Mia,” said Dan.
“But their love’s like a #planaria, try and chop it up & it will just regenerate.”
“I’m sure there’s a more romantic way of saying that.”
“Didn’t want her prince to get married?”
“She does want grandchildren.” #vss365
A snake-headed flatworm (Rhynchodemus sylvaticus), I think. They eat mollusks, springtails, spiders, and small insects. New Paltz, NY. #planarium #planaria #nature #flatworm https://www.youtube.com/watch?v=AOslBRx4lT0
When I was a child, I used to go through my Dad's #invertebrate #zoology textbook left over from college.
I remember being fascinated by the #worm you could cut down the middle and it would grow two heads.
Who knew this would be relevant to current events almost 60 years later?!

Byproduct of brain hunt [G. tigrina x G. sinensis morphology examination] - pharynx of Girardia sp., cresyl acetate, frontal - 8 frames, 250x. All 3 branches of intestine are visible as well -2 are visible as long lumens alongside of the pharyngeal pouch. #histology #planaria #planarian #microscopy #zoology
Body part #regeneration appears to be a whole-body affair.

#Planaria are freshwater #flatworms that have become a key model for studying #regeneration and #stem #cells, as they can regenerate any part of the body, even the head. But how does the animal know what part of its body is missing and what kind of tissue it needs to #regenerate?

'Why some animals can regenerate while many others cannot remains a fascinating question. Even amongst planarian flatworms, well-known for their ability to regenerate complete animals from small body fragments, species exist that have restricted regeneration abilities or are entirely regeneration incompetent. Towards the goal of probing the evolutionary dynamics of regeneration, we have assembled a diverse live collection of planarian species from around the world.'
Great article.
