Stem cells are cells found in all multicellular organisms that can differentiate into diverse cell types and self-renew to produce more stem cells. The document discusses the ethical issues surrounding the creation, treatment, and destruction of human embryos for stem cell research, noting that embryos are not fully developed in the first eight weeks after fertilization and it is difficult for some to view embryos as human due to their inability to see or sense them. It questions whether embryos should have the same rights as humans.
