Confocal microscopy image of human embryonic kidney cells

Confocal microscopy image of human embryonic kidney cells. Nanoparticles filled with human immunoglobulin were delivered to the cells. The cell nucleus is blue, endosomes (which sequester materials taken up by cells) are labeled in pink, and the immunoglobulin proteins are labeled with a green fluorescent tag. The nanoparticle's cargo has spread widely through most of the cells (green) without it being trapped in endosomes.
