Mimicking the "Seed and Soil:" The State of PDX Models of Breast Cancer Metastases

Why do the quaintest analogies stick to biology’s most morbid phenomena? Look no further than English surgeon Stephen Paget’s “seed and soil” model for breast cancer metastasis for a prototypical example. In his 1889 publication in the Lancet, Paget...
