This 3D tissue imaging video presents a volumetric view of human placental tissue, highlighting the PD-L1 signal in cyan throughout the tissue architecture. PD-L1 is associated with immune regulation at the maternal-fetal interface, where maternal and fetal biology interact in a highly organized spatial environment.

By moving beyond thin sections, 3D imaging enables observation of how molecular signals distribute through depth and across entire tissue structures. This perspective supports a more complete view of placenta biology, immune tolerance, tissue organization, and spatial relationships that are difficult to capture in a single 2D plane.

This dataset illustrates the value of volumetric tissue imaging for spatial biology, fluorescence imaging, immune microenvironment research, and quantitative tissue analysis across full tissue volumes.
