Figure shows a monolayer (~50% of plastic surface covered with cells) of HeLa cells with typical morphology under low magnification using phase-contrast microscopy (40X objective). Note the subconfluent monolayer of cells with the unoccupied surface and cell boundary and the condensed nuclear chromatin.
The phase-contrast microscopic images show the typical cellular morphology of HeLa cells grown in vitro in cell culture medium. The HeLa cells were cultivated at 37oC under 5% CO2 in Dulbecco modified Eagle medium containing 5% fetal calf serum.
HeLa cells (1) are a human cervical cancer cell line used in research and industrial settings to investigate cell biology, cancer, and virus propagation.
