Cellular metabolism controls all major cellular processes, including energy generation, cell identity, migration, and differentiation. It is highly dynamic and compartmentalized, whereby metabolites are actively segregated into organelles with distinct functional consequences. Visualization of carbon (red) and nitrogen (blue) assimilation by HEP-G2 cells incubated in growth medium with 13C and 15N isotope labels. Phosphorous distribution map is shown in green.
Results are shown for different embedding media (A-C).
A) LR white 2 % Glutaraldehyde
B) KM4 1% Glutaraldehyde
C) KM4 0.2% Glutaraldehyde
