Metastasis of melanoma poses significant threats, especially to the brain, with low survival rates once advanced. A new microphysiological system developed by Reed-McBain et al. simulates tumor-stroma interactions in the brain, allowing for detailed metabolic assessments and visualization of nutrient diffusion. This innovative model offers potential improvements in therapeutic screening for melanoma brain metastases.
