from Dr. David Seldin showing some patterns typical of transgenic animals
and showing the variations sometimes seen in some transgenic systems. Sample 3-1 has a markedly atypical hyperplasia
(MIN). Sample 3-2 has lung without metastasis.
Sample 3-3 has an example of a pure squamous
cell carcinoma. Sample 3-4 has a papillary
carcinoma with fibrosis in the adjacent tissue.
