No branches can be seen even in the routine histological stains (thionin, cresyl violet) still used nowadays (B).
But although government agencies now admit that neurotoxins - for example isomers of tri-cresyl phosphate - are present in these fumes, they claim their quantities pose no threat to health.
One slide from each set was stained with cresyl violet for assessing integrity of retinal lamination.
Retinal sections were stained with cresyl violet for examining general retinal lamination and with photoreceptor cell-specific antibodies (rhodopsin, cone arrestin), which showed the preservation of cone and rod photoreceptors within the MSC treated animals.
Retinal sections stained with cresyl violet indicate substantial preservation of photoreceptors across the retina in MSC treated eyes at P90, while in control eyes (sham injected (B) and untreated (C)): only a single layer of photoreceptors remained.
In brief, cryosections (40 µm thickness) spanning the rostral-caudal extent of the injured cortex were selected and stained with cresyl violet by an experimenter given only the animal's identifier code.
Every other section was mounted on a gelatin-coated glass slide and stained with cresyl violet to visualize Nissl substance.
Every twelfth section was stained with 1% cresyl violet.
O (15-30 sec), stained with 1\% cresyl violet in 1 M sodium acetate (~30 sec), rinsed 2× with DH
33P-labelled sense and antisense riboprobes were hybridized to serial parasagittal sections of additional (n = 4-6) adult male zebra finches followed by phosphorimager autoradiography (Typhoon 9410, GE Healthcare) for a global assessment of brain mRNA distribution, or emulsion autoradiography followed by Nissl (cresyl violet or toluidine blue) counterstaining for regional and cellular analysis.
