摘要: Abstract Expression of the proliferating cell nuclear antigen (PCNA) was examined in normal rat intestinal tissues and carcinogen-treated nonneoplastic neoplastic colonic mucosa. In intestine, PCNA expression confined to expected region proliferative compartment. A strong correlation observed between labeling index both [ 3 H]thymidine ( R = 0.993, P 0.007) percent cells S phase as determined by flow cytometry 0.982, 0.018) location maximal staining for 0.997,
