You've probably heard of organoids. That's where they take a stem cell and culture it in a petri dish. For simple homogeneous organs, it grows into something resembling the organ. This technology shows promise for transplants and grafts.
Well... meet the assembloid. Here, multiple stem cells of different kinds are cultured in the same dish, then connected together - "assembled", into potentially very complex organs.
Like brains. In a groundbreaking experiment, scientists have assembled the entire ascending sensory system for human pain.

Lab-Grown Nerve Circuit Recreates Human Pain Pathway - Neuroscience News
Researchers have recreated the human ascending sensory pathway in a lab dish, using organoids that model the key brain and spinal cord regions responsible for transmitting pain.
