Poem

"What do you want to be when you grow up?"

The embryonic stem cell couldn't make his mind up

With pluripotency, he didn't have to decide

He could be anything at all when the time was right

The adult stem cell, who was a bit more mature

Did everything that was expected of her

Followed those in her surrounding space

When a teammate was sick, happily took their place

she was un specialized but her fate was decided

Her heart held the key to her future inside it

Like a caterpillar as a butterfly wakens,

Embryonic and adult had differentiation

Both got their scripts and dressed for their roles

As liver or skin cells, for the good of the whole

With countless costars, they played their parts well

A standing ovation for the stem cell
