Introduction:
Sox1 is a transcriptional factor from SOX protein family. It is one of the earliest and most specific markers for neural progenitors and expressed throughout the central neural system during early embryo development1, 2. PrimCells is proud to isolate and provide to the research community the culture of Sox1-EGFP ESCs from transgenic knock-in mice. These cells were cultured in standard ESCs medium on gelatin coated plates and be used as a powerful tool to examine the process by which mESCs acquire neural identity.
ES cell culture and monolayer neural differentiation procudures
Sox1-GFP mESCs should be maintained in the stem cell culture medium to keep the pluripotent state (Figure 1).
For monoculture neural differentiation, dissociate and plate the undifferentiated Sox1-GFP mESCs on to 0.1% gelatin-coated tissue culture plastic at a density of 1-3x104/cm2 in serum-free N2B27 medium. Renew N2B27 medium every 2 days. GFP positive cells can be observed on Day 5 (Figure 2).

Growth Medium
Embryonic stem cell medium
DMEM: 415ml
FBS: 75ml (HYCLONE LABORATORIES INC, Cat# SH30070.03EH)
L-Glutamine: 5ml
MEM NEAA: 5ml
1-Thioglycerol: 4.3ul
LIF: 50ul LIF: 50ul (10ng/ml final concentration) (PrimCells, Cat# PFHSA01)

N2B27 medium for neural differentiation
N2B27 is a 1:1 mixture of DMEM/F12 (Gibco, Paisley, UK) supplemented with modified N2 (25 μg/ml insulin, 100 μg/ml apo-transferrin, 6 ng/ml progesterone, 16 μg/ml putrescine, 30 nM sodium selenite and 50 μg/ml bovine serum albumin fraction V (Gibco)) and Neurobasal medium supplemented with B27 (both from Gibco).
Alternatively, Ndiff227 (StemCells INC, Cat# SCS-SF-NB-02) is ready-to-use medium for the neural differentiation of mESCs in adherent monoculture conditions as described in Ying QL et al (2003)2.
