• Stem cells? They're the superheroes of our body! Present in several adult human tissues like bone marrow, skin, and liver.
• Superpower? Regeneration & repair. They're the reason you heal after a scrape or bruise. Cool, huh?

• Imagine a cozy home for stem cells. That's the 'stem cell niche'.
• It’s not just any home; it has to be perfect to keep the stem cells chillin' (inactive & undifferentiated) but also let them party hard (proliferate & differentiate) when needed.

• Inside the striated (or skeletal) muscle, stem cells are like sleeping ninjas. They chill until there's an injury.
• Get hurt? These ninjas wake up, multiply, and become muscle tissue, mending the damage. It’s like having a backup army for your muscles!

Real-World Example: Think of a torn teddy bear. These cells are the magical threads that stitch it back up!
