Figure 2 Immunocytochemistry staining. Different arrows highlight possible different cell types. Different arrows highlight possible different cell types. Antibodies for CD44 (SP37, Ventana 790-4537), CD133 (polyclonal, biorbyt, orb99113, 1:100), CD45 (LCA, 2B11 and PD7/26, Ventana 760-4279), Ki-67 (30-9, Ventana 790-4286), Wt1 (6F-H2, Cell Marque 760-4397), nestin (10C2, Sigma-Aldrich), Nanog (polyclonal, Abcam, ab80892, 1:100), OCT4 (MRQ-10, Cell Marque 760-4621), SOX2 (SP76, Cell Marque 760-4621), CK5 (SP27, Cell Marque 760-4935), CD34 (QBEnd/10, Ventana 790-2927), P63 (4A4, Ventana 790-4509), Thymosin β4 (Tβ4; polyclonal, abcam, ab14334, 1: 1000) and CK14 (SP23, Cell Marque 760-4805) were used for immunocytochemistry. Sample preparation was performed using standard validated cytologic protocols (ThinPrep Preserv Cyt solution, ThinPrep 5000 system, https://www.hologic.com). The Ventana automated stains system (http://diagnostics.roche.com) was used for immunocytochemistry staining and a qualitative analysis was performed by three different pathologists comparing the reactivity of different markers in slides of the same sample using an individual scoring system (morphological parameters, % of number of stained cells, area, and intensity of the stain). A: Immunocytochemistry staining for CD45; B: Immunocytochemistry staining for CD133; C: Immunocytochemistry staining for CD44. Solid arrow: Negative stem cell; Hollow arrow and triangle: Positive stem cell.
