Effects on Cell Division and Growth

Cell division and growth are fundamental processes for the development and maintenance of living organisms. However, under microgravity conditions, these processes are significantly influenced. The mitotic spindle, responsible for segregating chromosomes during cell division, undergoes alterations in microgravity, leading to abnormal cell division and growth patterns. This phenomenon has been observed in various cell types, including human cells, plant cells, and even unicellular organisms like bacteria and yeast.
Microgravity-induced changes in cell division can have profound implications for the development and regeneration of tissues, organ systems, and overall growth of living organisms in space.
