There is no cell culture for depression. You can't see it on a bone scan or an x-ray. Not everyone with depression will show the same behavioral symptoms.

Soon after Harris's HeLa-chicken study, a pair of researchers at New York University discovered that human-mouse hybrids lost their human chromosomes over time, leaving only the mouse chromosomes. This allowed scientists to begin mapping human genes to specific chromosomes by tracking the order in which genetic traits vanished. If a chromosome disappeared and production of a certain enzyme stopped, researchers knew the gene for that enzyme must be on the most recently vanished chromosome. Scientists in laboratories throughout North America and Europe began fusing cells and using them to map genetic traits to specific chromosomes, creating a precursor to the human genome map we have today.

[Davidson] Black procured cadavers for research, obtained from the Peking police department. These cadavers were mostly of people who had been executed for various crimes; the police regularly sent Black truckloads of the bodies of the executed convicts. Execution in China was by beheading, and thus the cadavers Black received lacked heads and had mutilated necks. After some time, he asked the police whether there was any possibility of getting better dead bodies for research - corpses that were intact. The next day, he received a shipment of convicts, all chained together, with a note from the police asking him to kill them in any way he chose.
