During his studies on inflammatory exudates, Rudolf Virchow observed that the increased number of cells in the exudates was due to the formation of new cells by pre-existing cells. He also studied that the formation of new cells from the preexisting cells is responsible for wound healing and for normal growth and development of living beings.
When scientists conduct an experiment and analyze the results, the next step is to write up a report that describes the experiment and the results and submit it for publication in a scientific or medical journal that is “peer reviewed.”
