Cow-cells in vitro won’t moo, but they ain’t hard to clone.
Myocytes [1] can be lined up, much like neurons or bone.
Conveyor-belt ‘Dolly’s, on packing-house trolleys might frighten consumers like you.
PETA surely will grouse if calves have to die young
To make BSE-free [2] beef Ragú.

Stem-cells, don’t let your babies grow up to be meatloaf;
Don’t let ‘em be Big Macs or mulligan stew,
Make them be sirloins or prime ribs ‘au jus’.
Stem-cells, don’t let your bovine genes morph into burgers;
They’d sure land up bunned, and likely be shunned by
Lovers of côtelettes-de-veau.

Foodies like trendy new bistros and fresh local produce
Tonight’s Steak Tartare from the lab shouldn’t get them uptight.
Abattoir workers feel threatened,
But coliform runoff and tainted meat lessened,
Lean cuisine - it’s all protein; for the future a blessing
To feed 8 billion souls every night.

Stem-cells, don’t let your offspring get smothered in goulash;
Don’t let ‘em be Big Macs or mulligan stew,
They’d feel more ‘mignon’ as prime ribs ‘au jus’.
Stem-cells, don’t let your progeny flower into burgers;
They’d sure land up bunned, and likely be shunned by
Lovers of châteaubriand.

[1] myocyte = (isolated) muscle cell
[2] BSE = bovine spongiform encephalopathy, “mad-cow” disease. Cloning might permit development of disease-resistance in cattle.
