Flow cytometric characterization of marine microbes.

The analysis of marine phytoplankton using flow cytometry has enabled the discovery of new taxa and has contributed new understanding to the dynamics and ecological contributions of phytoplankton to the global carbon cycle. Marine phytoplankton are uniquely suited to analysis by flow cytometry because of their size, pigment content, and ability to remain in suspension. Cytometric analysis of marine populations is not without challenges.

Synergy between erythropoietin and stem cell factor during erythropoiesis can be quantitatively described without co-signaling effects.

Synergistic interactions between cytokines underlie developmental processes fundamental to tissue and cellular engineering. However, a mechanistic understanding of the cell-specific and population-mediated effects is often lacking. In this study, we have investigated the synergistic generation of erythroid cells in response to erythropoietin (EPO) and stem cell factor (SCF).
