text: Check it out, yo, I'm 'bout to drop some knowledge,
  Listen up, 'cause I'm 'bout to go to college.
  We got a technique for isolation, no joke,
  Adult Schwann cells from dorsal root ganglia, let it soak.
  
  First, we take them DRG explants, no cap,
  Embed 'em in collagen gels, make 'em adapt.
  Culture 'em for three days in a serum-free zone,
  ScC be migratin', leavin' the explant all alone.
  
  Then we switch it up, let 'em grow some more,
  In a serum-supplemented medium, they soar.
  By day ten, we got ScC, no need to fuss,
  About 2.5 x 10(5), purer than 95%, trust.
  
  This culture system, it's the real deal,
  Gives us plenty ScC, faster, it's a steal.
  We use 'em to study how age affects their game,
  Attachment, growth, survival, all that's in the frame.
  
  When it comes to attachment, adult ScC ain't slack,
  On type I collagen or polylysine, they got the knack.
  Just like newborn ScC, they hold it down,
  But adult ScC on collagen, they grow and survive, no clown.
  
  Neonatal ScC, they don't respond the same,
  Collagen ain't their thing, it's a different game.
  Age-related differences, that's what we see,
  In vitro, ScC properties vary, it's the key.
