BrdU labels cells during the S phase, whereas Ki67 labels cells in the G1, S, G2, and M phases (only Go cells should be negative for Ki67). However, using only one marker may yield only partial information, while using both will ensure and enhance the reliability of the obtained ...
Another way to research cell proliferation is by looking at the specific proteins that are expressed in proliferating cells exclusively. The Ki-67 protein (MKI67) is a cellular marker for cell proliferation (Figure 3). Ki67 is present during all active phases of the cell cycle (G1, S, G...
The proliferating cells were negative for the podocyte markers, but stained positive for the PEC markers and the cell proliferation marker Ki-67. The proliferating PAX-2 and CK8 positive cells that covered the capillary tuft were always in continuity with PAX-2/CK8 positive cells lining Bowman'...
Proliferating Cell Nuclear Antigen: A New Marker of Proliferation in CancerPCNAPROLIFERATING CELL NUCLEAR ANTIGENNUCLEAR ANTIGENCANCERProliferating cell nuclear antigen (PCNA) is the auxiliary protein of DNA polymerase It is induced in late G1 and S phases following mitotic stimulation of resting cells ...
Recentlyproliferating cell nuclear antigen(PCNA), an immunohistochemical marker abundant in activelyproliferating cells, has been proposed as an aid in differentiating betweenNSOIandlymphoproliferative diseases. In one study, PCNA activity was markedly increased in high-grade lymphoma compared to that in lo...

The left lane is a molecular weight marker showing the molecular weight of 35,000 and 25,000. interacts with the N-terminal domain of MsePCNA2. In the same manner, an equimolar mixture of MsePCNA1, MsePCNA2-CyPet and YPet-MsePCNA3 showed a high FRET signal, which decreased upon ...
Bromo-deoxyuridine (BrdU) incorporated by S-phase traversing cells is an exogenous marker of replicating cells, whereas proliferating cell nuclear antigen (PCNA) is an endogenous marker of replicating cells. We have applied monoclonal antibodies to BrdU and PCNA to study cell kinetics in tooth germ...
This work demonstrated that CEA is a marker of cell differentiation antigen not expressed by stem cells. In order to further study the characteristics of stem cells in breast cancer, the expression of hormone receptors has been studied. It is known that approximately two thirds of breast cancer...
On days 1–5, cyclin D1-immunopositive cells were decreased with an increased expression in p21 mRNA, indicating G1 arrest in the cell cycle. The affected renal epithelial cells began to react to EP4 receptor, but not to EP2 receptor. Some EP4 receptor-reacting epithelial cells gave a ...
