Coevolution of solid stress and interstitial fluid pressure in tumors during progression: Implications for vascular collapse

Stylianopoulos, T.; Martin, J. D.; Snuderl, M.; Mpekris, F.; Jain, S. R.; Jain, R. K. (2013)

The stress harbored by the solid phase of tumors is known as solid stress. Solid stress can be either applied externally by the surrounding normal tissue or induced by the tumor itself due to its growth. Fluid pressure is ...

Commitment to erythroid differentiation in mouse erythroleukemia cells is controlled by alterations in topoisomerase IIα phosphorylation

Constantinou, Andreas I.; Vaughan, A. T. M.; Yamasaki, H.; Kamath, N. (1996)

To explore the program of cell differentiation in Friend murine erythroleukemia (MEL) cells, we used three clonal variants: phorbol 12- myristate 13-acetate (PMA)-hypersensitive TS-19-101, PMA-resistant TR19-9, and ...

Comparative developmental anatomy of the murine and human definitive placentae

Georgiades, Pantelis; Fergyson-Smith, A. C.; Burton, G. J. (2002)

The placenta of eutherian mammals is a remarkable biological structure. It is composed of both zygote-derived and maternal cells, and mediates the complex interactions between the mother and the fetus that are necessary ...
