Stem cell crosstalk with the microenvironment creates a loop of tumor-promoting factors

What drives tumor growth? Is it a few rogue cells imposing their will upon healthy tissue, or diseased tissue bringing out the worst in otherwise peaceable cells? Or is it a back-and-forth, a dialogue between the two?

Powerful imaging tool creates 3D atlas of the spectrum of tuberculous and COVID-19 lung lesions

Gross anatomy reveals three-dimensional shapes of pathology at a large scale. Histology, in contrast, reveals the microscopic anatomy of biological structures. But that magnification comes at a cost - histology shows only two-dimensional shapes because it studies small, flat slices of stained tissue.
