In 1964, authors James Till, Ernest McCulloch, and Louis Siminovitch, published A Stochastic Model of Stem Cell Proliferation, Based on The Growth of Spleen Colony-Forming Cells, which discussed possible mechanisms that control stem cell division. The authors wrote the article following their experiments with spleens of irradiated mice to demonstrate the existence of stem cells, had unknown properties. In their previous experiments, Till and McCulloch noticed that many similar-looking colonies of cells formed on the spleens of irradiated mice, but those colonies had a highly variable number of stem cells. They could not explain why some stem cells gave rise to many stem cells while others only gave rise to a few. In the article, the authors propose an explanation for how stem cells divide and renew, and provide both a greater understanding as to how cancerous tissues may arise due to unchecked stem cell division as well how stem cells can aid in cancer therapy.
