Rudolf Virchow’s development of cellular pathology was significantly influenced by the work of Robert Remak, a German neuroanatomist and embryologist.1

In 1852, Remak was among the first to demonstrate that cell division is the mechanism responsible for the multiplication of cells to form tissues. Remak concluded that new cells arise from existing cells in both healthy and diseased tissues, a concept that helped Virchow realize that the origin of cells from preexisting cells—rather than from amorphous material—could provide vital insights into pathological processes.1

While the aphorism omnis cellula e cellula ("every cell is derived from a preexisting cell") was originally coined by François Vincent Raspail in 1825, Virchow integrated these findings into a comprehensive system of cellular pathology. By formalizing these ideas in his 1858 lectures and subsequent publications, Virchow transformed scientific thought in biology, establishing the cell as the fundamental unit of both physiology and pathology.1
