|January 1, 1984
Summary
Human embryonic kidney (HEK) cells successfully attached, spread, and survived in microgravity during a space mission. This demonstrates the feasibility of space-based bioprocessing for cell culture and enzyme production.
Area of Science:
- Biotechnology
- Space Biology
- Cell Culture
Background:
- Human embryonic kidney (HEK) cells are being investigated for space-based electrophoretic separation.
- Cell attachment and survival are critical for urokinase production in microgravity.
- Previous research has not fully established HEK cell behavior in spaceflight conditions.
Purpose of the Study:
- To assess the attachment, spreading, and survival of HEK cells in microgravity.
- To evaluate the viability of HEK cells for bioprocessing applications in space.
- To determine the impact of spaceflight on HEK cell adherence and survival.
Main Methods:
- HEK cells were cultured in an incubator aboard the Space Shuttle 'Challenger'.
- Cell attachment, spreading, and survival were analyzed post-flight.
- Microgravity conditions (< 10(-3) x g) were compared to ground controls (1 x g).
Main Results:
- HEK cells demonstrated successful adherence and spreading on the substrate in microgravity.
- Cell survival rates in microgravity were comparable to ground controls.
- The study confirmed that HEK cells can thrive in the space environment.
Conclusions:
- HEK cells can be successfully cultured and maintained in microgravity for bioprocessing.
- Spaceflight does not impede essential cellular functions like attachment and survival for HEK cells.
- This research is a significant advancement for future in-space biomanufacturing and pharmaceutical production.
