: '''Bone Marrow Transplants (1968)''' → The first-ever "Stem Cell Therapy," which uses a donor's "HSCs" to "Re-grow" a cancer patient's entire immune system.
: '''Human Embryonic Stem Cells (1998)''' → James Thomson first isolated human ESCs, launching the "Great Stem Cell Debate" in politics and ethics.
: '''Planaria (The 'Immortal' Worm)''' → A worm that is "Made of stem cells." If you cut it into 200 pieces, it becomes 200 "New worms" in 2 weeks. It is the "Dream" of stem cell research.
: '''Stem Cell 'Tourism'''' → A dangerous modern trend where people pay for "Unproven injections" in countries with no rules, often leading to "Teratomas" or "Cancer" because the stem cells "Got confused."
