SCIENCE RESULTS FOR EVERYONE
To fully understand how microgravity affects human health, and develop effective countermeasures to those effects, scientists need to know what is happening to the cells in the body. This investigation looks at the genes that respond to gravitational changes and ways to control those responses, in particular formation of “domes,” fluid-filled structures that spontaneously form in cell cultures of a particular kidney cell line. Early results indicate microgravity exerted little influence on the structure of the cells or their gene behavior, and that space radiation appear to have a greater impact than microgravity. This investigation’s innovative methodology may prove useful in other scientific disciplines such as radiation biology and developmental biology.
Experiment Description
DESCRIPTION
Two kinds of amphibian cultured cell lines are cultured in Dome Gene. A-6 cell line derived from kidney and A-8 cell line derived from liver are used. They show different types of cell differentiation and morphogenesis. While they are cultured under microgravity,we observe the shape and state of the cells. And, we examine the known and unknown gene expression by DNA array assay using fixed and frozen recovery sample.
