Cranial Nerve Development Experiment


Embryo details

Species:Gallus gallus domesticus
Embryo Name: MH006
Staging description:
Cryoprotection: Yes
Material label and storage: Stored in a vial filled with 30% sucrose PBS solution labelled MH006 at room temperature.

Experiment details

Objective: To successfully cut good histological quality ST28 sections
Procedure: Detailed experimental protocol can be found here
Comments: This was not a serial sectioned embryo. The quality of the tissue was very poor. The decision was made not to complete cutting the whole embryo for this reason.

ObservationsThe poor quality of the sections was evident before staining. Did not complete sectioning due to this.

(Include in your observations, eg ,were the sections serial, was any section lost, was quality assessed, etc)

Coverslip15 minutes The slides used in this experiment were not frosted therefore a diamond pencil had to be used to label the slides. During coverslipping the liquid made it quite difficult to see the writing.


Please see following entry To assess these sections the following questions were included:

  • What are the cell types present?
  • Are the cells intact?
  • What improvements can be made ?
