Interpreting the detritus left after starving and poisoning cell lines with antibiotics and claiming these are distinct “particles” with a purpose is as scietifically meaningful as Tea Leaf reading.

What should anyone expect from starving and poisoning? Detritus. Your commentary on the red herring is appreciated.

Great article, its about time someone out exosomes to bed. I think Kaufman was still mentioning them in his latest debate with kirsch - cringe.

Just re what these particles are - The fixing and dehydration of the sample in preparation for placing it into the electronic microscope removes all lipids from the sample. At the time of observation of an electron micrograms no lipids are present in the sample.

Harold Hillman makes this point in his 47 questions for biologist and an example of this issue can be found here ‐ https://www.sciencedirect.com/science/article/abs/pii/0005276066900130

The majority of the structures seen in electron micrographs are artifacts of the electron microscop process - they just do not exist at all in a living organism or even in a tissue culture. More often than not, they are the result of biological matter precipitating after chemical, dehydration and heat.
