- He demonstrated the existence of the medullary nerve sheath and its production in the process of structured cell division. Remak also was the first to demonstrate that the cerebral cortex consists of six layers and to assert that there are three germ layers in the early embryo and not four.

Dec 20, 2002 · Remak was nevertheless highly productive as a microscopist. His major contribution to cell theory was the evidence that new animal cells arise by binary fission of pre-existing cells.
By 1855 Remak was ready to assert the general conclusion implicit in much of the early cell theory: that the production of nuclei or cells is really only division of preexisting nuclei or cells. From: Remak, Robert in A Dictionary of Scientists » Subjects: Science and technology. Reference entries. Remak, Robert (1815–1865)
low nuclei inside a single cell's cytoplasm or, as Remak proposed, from division of nuclei without subsequent cytoplasmic division. This paper will discuss how Robert Remak explained this peculiar cell and the scientific basis for his claim that division is the only way cells reproduce.
Remak set out to prove that cells originate from division. His idea was to stain or harden the cell membrane and thus be able to see the cell divide. Remak experimented with many chemicals before finding that a mixture of copper sulfate, vinegar, and alcohol worked to solidify the cell membrane.1,2-Remak's view of cell division.3
Mar 1, 2018 · Robert Remak (1815–1865) (Fig. 3) like Schwann and Virchow, trained in Müller's laboratory at the University in Berlin. In 1852, Remak summarized his early work on cell generation: “Since the publication of the cell-theory, it has seemed to me that the extracellular creation of animal cells is as unlikely as the generation “aequivoca ...

During the 1850s, Robert Remak (1815–1865) and Rudolph Virchow (1821–1902) independently (Remak in 1855 and Virchow in 1855–1858) asserted that every cell was the result of the division of a previous cell.
Schleiden's theory of free cell formation through crystallization was refuted in the 1850s by Robert Remak, Rudolf Virchow, and Albert Kolliker. In 1855, Rudolf Virchow added the third tenet to cell theory.
