Isolation and Culture of Murine Tongue Epithelial Cells: A Procedure to Isolate and Culture Tongue Epithelial Cells from Mouse Model

Abstract

In this video, we describe the isolation of epithelial cells from a murine tongue. These cells can be further cultured to give rise to cell colonies.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Isolation and Culture of Primary Cells Euthanize a 6-week-old male or female B6;129-Gt(ROSA)26Sortm1(CAG-cas9*,-EGFP)Fezh/J by CO₂ asphyxiation or any other IACUC approved protocol. NOTE: These CRISPR/Cas9 knockin mice have Cre recombinase-dependent expression of cas9 endonuclease …
