2. Figure 1
Immunofluorescent double labeling for cell cycle phase markers. (A) Cyclin D1 (green) and cyclin A (red) in hepatocellular carcinoma; colocalization not seen. (B) Cyclin A (green) and cytoplasmic cyclin B1 (red) in regenerating liver; colocalization seen in <2% of cyclin A-positive hepatocytes. (C) Cytoplasmic cyclin B1 (green) and PH3 (red) in hepatocellular carcinoma; colocalization only when nuclear cyclin B1 was also present. (D) Cyclin A (green) and PH3 (red) in regenerating liver; colocalization in <5% of cyclin A-positive cells. Arrow indicates cell positive for both cyclin A and PH3.

(B) Cyclin D1, maximal during G1. (C) Cyclin A, maximal during S phase. (D) Cyclin B1, cytoplasmic during G2. (E) PH3, detectable during mitosis.

4. Figure 3
Immunoperoxidase stain in a liver biopsy specimen from a patient with liver regeneration following transplant-related acute ischemic-reperfusion injury using cell cycle phase-specific antibodies. (A) Mcm-2, present throughout cell cycle. (B) Cyclin D1, maximal during G1. (C) Cyclin A, maximal during S phase. (D) Cyclin B1, cytoplasmic during G2 (closed arrow). Cyclin B1 translocates to the nucleus at the start of mitosis (open arrow). (E) PH3, detectable during mitosis.

5. Figure 4
Hepatocyte Mcm-2 and cell cycle phase markers comparing chronic HCV and liver regeneration. (A) Percentage Mcm-2-positive hepatocytes in HCV versus regeneration (P = .002). B–E give the median of results expressed as percentage of Mcm-2-positive hepatocytes for each case, termed labeling fraction. (B) Cyclin D1 (P = .2). (C) Cyclin A (P < .0001). (D) Cyclin B1 (P < .0001). (E) PH3 (P < .0001). For these and all subsequent figures, the black bar in the middle of the box represents the median, the box stretches between the lower and upper quartile, and the whiskers extend to the range of the data or 1.5 times the box length, whichever is shorter.
