The physical existence of ectoplasm has not been scientifically demonstrated, and tested samples purported to be ectoplasm have been found to be various non-paranormal substances. [ 4 ] [ 12 ] Other researchers have duplicated, with non-supernatural materials, the photographic effects sometimes said to prove the existence of ectoplasm.
Cells may undergo fast transitions between blebbing and lamellipodium-based motility as a means of migration. However, the rate at which these transitions are made is still unknown. Tumor cells may also exhibit rapid transitions between amoeboid motility and mesenchymal motility, another form of cellular movement.
Ectoplasm (also exoplasm) is the non-granulated outer part of a cell's cytoplasm, while endoplasm is its often granulated inner layer. It is clear, and protects as well as transports things within the cell. [1] Moreover, large numbers of actin filaments frequently occur in the ectoplasm, which form an elastic support for the cell membrane. [2]
Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.
Stanisława P. with ectoplasm. Stanisława Popielska (born c. 1893) most well known as Stanisława P. was a Polish spiritual medium who was alleged to have produced ectoplasm and the psychokinetic movement of objects.

Richet devoted many years to the study of paranormal and spiritualist phenomena, coining the term "ectoplasm". He believed in the inferiority of black people, was a proponent of eugenics, and presided over the French Eugenics Society towards the end of his life.
Filopodia (or filose pseudopods) are slender and filiform with pointed ends, consisting mainly of ectoplasm. These formations are supported by microfilaments which, unlike the filaments of lamellipodia with their net-like actin, form loose bundles by cross-linking. This formation is partly due to bundling proteins such as fimbrins and fascins.
