Fig 2. Flow cytometry, Immunofluorescence and qRT-PCR of WJ-MSCs.

Fig 2

(A). Representative flow cytometry of WJ-MSCs (n = 3). Cells express CD29, CD44, CD73, CD90, CD105, and are negative for the hematopoietic (CD34 and CD45) and endothelial (CD106 and CD133) markers. Black open histogram indicates controls signal; red shaded histogram represents positive reactivity with the indicated antibody. (B) Confocal laser images of Immunofluorescence using APEX-labeling system for conjugating primary antibodies; CD29-Alexa Fluor 594, CD34-, CD44-, CD90- and CD133- Alexa Fluor 488. CD73-PE and CD105-PE were manufacturer labeled. 600X magnifications (C) qRT-PCR of the prospective markers for RNA isolated from undifferentiated WJ-MSCs cells, values were expressed as a percentage relative to 1/dCt of GAPDH gene.
