Stem Cells in Space: Uncovering Their Role in Tissue Regeneration and Health

The video discusses NASA's research on stem cells in space, focusing on how microgravity affects tissue regeneration. Dr. Eduardo Almeida and Dr. Liz Blaber explain the importance of stem cells for health, the impact of space flight on these cells, and the implications for long-term space missions and regenerative medicine on Earth. The research uses models like mice and newts to understand these effects, highlighting the role of gravity in maintaining health.

What is the primary function of adult stem cells in the body?

• To regenerate tissues

• To produce energy
