Figure 9From: Impact of source tissue and ex vivo expansion on the characterization of goat mesenchymal stem cells Immunofluorescent staining of OCT4 in MSCs and fibroblasts. P5 cells were stained with antibodies against OCT4. OCT4 was localized in the cytoplasm of MSCs and fibroblasts, whereas staining for OCT4 was specific to the nuclei in the bovine blastocyst. Representative images are shown at 200X magnification.Back to article page
