Scientists at UCSF invented a microscopic “womb” material for growing artificial organs (organoids) from scratch.

Mount Sinai researchers have published the first organ-wide human skin spatial atlas from across the body. It provides an ...

This is a top-down cross-section of one of the 3D hollow spheres (lumenoids) that our cells can create. The different colors are for different proteins, which allows you to see some striking ...
