Embryo details


Species: Gallus gallus domesticus
Embryo Name: RC010
Embryo stage: ST25
Staging description: Staged by Reuben according to the Hamburger and Hamilton (1951) staging system. (Notebook entry 10th January 2011 ). Staging has not been confirmed.

  • Too grooves present but not distinct (<ST26).
  • Tail region segmented.
  • Visceral clefts still visible (<ST26).
  • Shape of the hindbrain has a sligh groove which resembles the images for ST25.


Fixation: PFA
Cryoprotection: None
Material label and storage: Stored in vial filled with PFA labeled RC-010 and placed in a container labeled 'Reuben's staged embryos' next to the dissection microscope.

Experiment details


Objective: To use as a practice embryo for staging.
Procedure: Staged the embryo by observing the embryo under a dissection microscope and comparing its morphological properties with those described in the Hamburger and Hamilton (1951) paper whilst looking at our own compilation of images organized by stage.
Comments:

Results

Embryo is approximately ST25.

Summary

This embryo may be used in further experiments as approximately a ST25 embryo however confirmation is needed.
