Ultrastructural Study of Microphysiological Systems of the Tumor Microenvironment

open access: yesSmall Science, Volume 6, Issue 4, April 2026.
We studied ultrastructural features of microphysiological systems (MPS) of the tumour microenvironment consisting of 3D multicellular tumour structures that were grown in hydrogel‐based cancer‐on‐a‐chip models. We selected two different MPS from our lab as examples and devised a sample preparation technique for their observation under dual‐beam focused
