16 blastomeres inclusive. $3.45 Each

If you want a set they have:
WW-30-9306 Embryology Set, General $336.00 Per set
A set of 25 slides designed for vertebrate embryology with special emphasis
on the chick. Pig slides are included for comparative study, while starfish
slides offer a clear general picture of early holoblastic equal cleavage.
Frog development slides show holoblastic unequal cleavage, formation of the
blastula, gastrula, yolk plug, and neural plate through neural tube stages.
The late neural tube stage gives students a clear picture of primary germ
layers.
