The researchers used a 3D bioprinted base of gold atoms to grow cancer cells in space.

BioServe Space Technologies, NASA's affiliated research center, is understood to be working on a research project called "Magnetic 3D Cell Culture."
the project uses a bioprinting technology developed on Earth to grow more realistic cancer cells on the International Space Station (ISS) to advance cancer treatment research.
in the human body, the structure of cancer cells is very complex, almost spherical, while in the laboratory (in vitro) cultured cancer cells only have a stratular structure.
center believe that in space, they can effectively grow 3D cancer cell structures that are closer to the structure of cancer cells in the human body.
using a bioprinting method called magnetic 3D cell culture, the researchers found that the micro-gravity environment on ISS could be used for their use.
by printing gold atoms into a polymer substation on human cancer cell cultures (in experiments they used lung cancer cells), researchers were able to use magnets to control cell structure and movement.
because gold atoms strongly bind to cell membranes, making them magnetically reactive.
technology may allow us to process cells in the sky in a way that is not currently possible.
earth, you put cells in a biofilm medium and the cells grow on its surface.
but it won't happen in space because there's not enough gravity to keep them on the surface.
so for now we're going to start with a medium on the ground to grow cells, then launch them into space, and then we're going to start experimenting," he said.
these magnetic particles, we can start growing cells in space, just like on Earth, " the researchers explained.
that adding gold atoms to cancer cells for operational purposes does not interfere with or affect the biological processes of cells, so it is feasible to use this bioprinting technique in cancer research.
addition, growing more realistic cancer cells may reduce drug development costs and may bring other benefits.
the study tested a new technology that other scientists could apply to their fields of study, as the case may be," the researchers concluded.
