Embryonic Stages

 

Incubated at 27°C Stained with 1.5% PTA Imaged in Perkin-Elmer 6x2 Processed in 3D Slicer Voxel Size: - Anolis sagrei embryo - stage 5 - 3D model by SangerLab (@SangerLab) [2b12c3d]

Stage 5

Both front and hind limb buds wider than they are long. Hindlimb buds are slightly bigger than forelimb.

Stage 6

Hindlimb more distinct than forelimb. Distal limb buds are paddle shaped.

Stage 7

Paddles wider than in previous stage. Medial digit condensation beginning to be visible.

Stage 8

Condensation of digit cartilages are visible with slight thinning of internal webbing but no regression.

Stage 9

Distal tips of digits freed of internal webbing. 4th digit noticeably larger.

Stage 10

Digital webbing receeded to half its length on digits. Slightly elongated medial digits.

Stage 11

Digital webbing has fully regressed. Pinching at distal tips eventually will form claws.
