At the beginning of the 19th century, various hypotheses circulated about cell proliferation, which became observable in plant and animal organisms as a result of advances in microscopy. While the proliferation of cells on the inner side of old cells,Charles F. B. de Mirbel, 1813Pierre J. F. Turpin, 1825 the attachment of vesicles to existing cells,Matthias Jacob Schleiden, 1838 or crystallization in the intercellular spaceTheodor Schwann, 1839 were postulated as mechanisms of cell proliferation, cell division itself had to fight for its acceptance for decades.
