That is due to preference as well as breeding habits. Most direct comparisons pertain to humanized mice. Furthermore, chemotherapies that act by causing DNA damage can have higher toxicity in scid mice, compared to Rag1 or Rag2 knockouts. The different cell types that make up the lymphoid and myeloid lineages are present within humanized NSG mice, and there is a significant amount of effort going into understanding how functional they are. . In 1961, microbiologist Leonard Hayflickargued that all of our cells (except eggs, sperm, and cancer) could only divide a finite number of times.
