  1. fibroblast Division in Microgravity Jennifer Jiang, Jasmine Kuo, Kara Lukas San Marino High School San Marino, California

  2. Background • Cell division is an integral component of life. • All organisms must go through the cell cycle in order to grow, develop, and reproduce. • Past experiments in simulated microgravity have shown that lack of gravity causes cells to divide at a slower rate.

  3. Purpose • To discover the effect of microgravity on cell division • To compare the rates of cell division in the absence and presence of gravity

  4. hypothesis • If cells are exposed to microgravity during their life cycles, then there will be a reduction in cell division because of • disorganization of microtubules • change in actin filaments • chromatin less dense • increased apoptosis

  5. Materials • Type 3 FME • Mouse embryonic fibroblasts • Eagle’sMinimum Essential Medium (EMEM) • FetalBovine Serum (FBS) • Formaldehyde • Light Microscope • Hemocytometer • Trypan Blue

  6. Assembly procedures Place experiment samples into the appropriate compartment of the FME. • Main Volume • 5.6 mL of EMEM • 0.56mL of 100% FBS • Short Ampoule A • 0.92 ml fibroblast cells • Short Ampoule B • 0.92 ml formaldehyde

  7. experiment • Initiation: crack Ampoule A • Termination: crack Ampoule B • Experiment lasted 9 days

  8. Data Number of fibroblasts

  9. Analysis/Conclusion • Growth is more favorable for cells in 37°C CO2 incubator. • Cell growth is greater when the original cell count is increased from 500 to 750. • More conclusions will be drawn after flight experiment returns.
