Questions and Answers on Stem Cells: Potentials in Regenerative Medicine
1. What are stem cells, and why are they important in regenerative medicine? Answer: Stem cells are undifferentiated cells capable of self-renewal and differentiation into various specialized cell types. They play a pivotal role in regenerative medicine due to their potential to repair or replace damaged tissues and organs. This capability is critical for treating conditions such as spinal cord injuries,...
