a) Schematic overview of cell isolation, sorting and
sequencing.
b) Flow cytometry plots of olig1:memEYFP-sorted cells
and wildtype control animals. Dotted lines indicate the gating used (example
from two independent experiments).
c) TSNE plot showing expression of
sox10 (total sample size n=310 cells).
Immunohistochemistry for Sox10 on transversal spinal cord sections of 7 dpf
Tg(olig1:nls-mApple), Tg(mbp:nls-EGFP) animals and quantification of
Sox10-expressing OPCs (olig1:nls-mApple-positive, mbp:nls-EGFP-negative) in
neuron-rich and axo-dendritic areas (100% (68/68) vs 100%
(49/49) pos cells, n=16 animals / 4 experiments). Dotted lines in the image
indicate the outlines of the spinal cord. Scale bar:10 μm.
d) TSNE plot showing expression of olig2 and
nkx2.2a (sample size as in panel c).
e) TSNE plot showing expression of ppp1r14bb,
mbpa, and plp1a (sample size as in panel c).
f) Confocal images with in situ
hybridisations for cspg4, gpr17,
myrf, and labelling of EDU incorporated cells on
transversal spinal cord sections of 7 dpf Tg(olig1:nls-mApple),
Tg(mbp:nls-EGFP) animals (see Fig. 2e, 2i, 2k,
2l for respective n numbers). Scale bar: 10 μm.
