text: Yo, listen up, let me break it down,
  The ovarian follicle, it runs the town,
  A functional unit, holdin' it tight,
  With an oocyte at the center, that's right.
  
  Surrounded by GCs, granulosa cells,
  They play a role, yo, it's all swell,
  They help the follicle grow and develop,
  Makin' moves, they ain't no rebels.
  
  Now pay attention, 'cause it's gettin' real,
  GCs got skills, they got the appeal,
  They're showin' plasticity, stem cell traits,
  Provin' themselves, they're breakin' the gates.
  
  In reproduction programs, they be retrieved,
  Along with oocytes, they ain't deceived,
  But currently, they get thrown away,
  In the future, yo, they could have their say.
  
  In regenerative medicine, they could shine,
  Researched and used, it's the grand design,
  Isolated GCs, they express the markers,
  OCT-4, NANOG, and SOX-2, they're the sparkers.
  
  Telomerase activity, it's off the charts,
  They're versatile, transformin' like arts,
  In vitro, they differentiate with grace,
  Into cell types, not found in this place.
  
  And check it, there's more, somethin' new,
  Transdifferentiation, it's comin' through,
  Explains ovarian conditions, that's the claim,
  GCs makin' moves, bringin' change to the game.
  
  So, keep an eye out, regenerative medicine's callin',
  GCs in the spotlight, they ain't fallin',
  With potential applications, they're on the rise,
  Breakin' barriers, reachin' for the skies.
