In 1855, Rudolf Virchow added the third tenet to cell theory. In Latin, this tenet states Omnis cellula e cellula. This translated to: 3. All cells arise only from pre-existing cells. However, the idea that all cells come from pre-existing cells had already been proposed by Robert Remak; it has been suggested that Virchow plagiarized Remak. [12]
The idea that cells can be generated de novo, by the "cytoblast" or otherwise, contradicted work by Robert Remak (1852) and Rudolf Virchow (1855) who decisively propagated the new paradigm that cells are generated solely by cells ("Omnis cellula e cellula "). The function of the nucleus remained unclear. [101]

According to historian Paul Weindling, Rudolf Virchow, one of the founders of modern cell theory, plagiarized Remak's notion that all cells come from pre-existing cells. [2] Remak had concluded this after observing red blood cells from chicken embryos in various stages of division.
Drawing of the head of a four-week-old human embryo. From Gray's Anatomy.. Embryo drawing is the illustration of embryos in their developmental sequence.In plants and animals, an embryo develops from a zygote, the single cell that results when an egg and sperm fuse during fertilization.
Illustration of the cell theory in the first edition of Virchow's Archiv für Pathologische Anatomie und Physiologie, 1847. The rise of popular materialism was encouraged by a critique of romantic-idealistic natural philosophy, [5] which became widespread after 1830 and had an equal influence on natural science, philosophy, and politics.
