Figure 1From: Horse bone marrow mesenchymal stem cells express embryo stem cell markers and show the ability for tenogenic differentiation by in vitro exposure to BMP-12BM-derived MSCs express stem cell marker protein Oct4. Cells (5th passage) were fixed and incubated with antibodies directed against Oct4. Immunoreactivity was detected with avidin, biotinylated horseradish peroxydase and 3,3'-Diaminobenzidine (DAB) (1B). 1A: negative control, incubated only with secondary antibody.
