Model Scientific Organism to Study Developmental Biology

  • Large cells to study development; easy to see
  • Clearly identify nervous system development
  • Excellent subject to study embryological topics
Frog eggs are large and the developmental stages are easy to observe within embryos. The formation of the neural plate, the basis for the nervous system, can be seen clearly. Frogs are helpful study models for comparative, developmental, and embryological studies. Choose from a variety of individual frog development slides.

Ordering information: We offer individual frog development slides of Frog, Gastrula (ls) h&e- Ventral lip; early yolk plug. Typical sagittal section. Shumway stage 11; Frog, Unsegmented Egg (sect) h&e- Typical sagittal section. Shumway stage 2.Frog, Early Cleavage (ls) h&e- Two to four cell stage. Typical sagittal section. Shumway stages 3–4; Frog, Late Cleavage (ls) h&e- Six to eight cell stage. Typical sagittal section. Shumway stage 5; Frog, Crescent Blastopore (ls) h&e- Dorsal lip and beginning of the involution. Typical sagital section. Shumway stage 10; Frog, Yolk Plug (ls) h&e- Typical sagittal section. Shumway stage 12; Frog, Neural Plate (cs) h&e- Early folds; medullary plate prominent.
