Abstract

Endometrial stromal cells (EMSCs) obtained from porcine uterus (n = 6) were positive for mesenchymal stem cell markers (CD29, CD44 and CD90), and negative for epithelial marker CD9 and hematopoietic markers CD34, CD45 analyzed by flow cytometry. Further the cells were positive for expression of mesenchymal markers, CD105, CD140b, and CD144 by PCR. Pluripotent markers OCT4, SOX2, and NANOG were positively expressed in EMSCs analyzed by Western blotting and PCR. Further, differentiation into adipocytes and osteocytes was confirmed by cytochemical staining and lineage specific gene expression by quantitative realtime-PCR. Adipocyte (FABP, LPL, AP2) and osteocyte specific genes (ON, BG, RUNX2) in differentiated EMSCs showed significant (p < 0.05) increase in expression compared to undifferentiated control cells. Neurogenic transdifferentiation of EMSCs exhibited distinctive dendritic morphology with axon projections and neuronal specific genes, NFM, NGF, MBP, NES, B3T and MAP2 and proteins, B3T, NFM, NGF, and TRKA were positively expressed in neuronal differentiated cells. Functional analysis of neuronal differentiated EMSCs displayed voltage-dependence and kinetics for transient outward K+ currents (Ito), at holding potential of −80 mV, Na+ currents and during current clamp, neuronal differentiated EMSCs was more negative than that of control EMSCs. Porcine EMSCs is a suitable model for studying molecular mechanism of transdifferentiation, assessment of electrophysiological properties and their efficiency during in vivo transplantation.
