Comparative evaluation of fracture healing potential of differentiated and undifferentiated guinea pig and canine bone marrow-derived mesenchymal stem cells in a guinea pig model.

Background And Aim: This work was conducted to compare the therapeutic potential of undifferentiated and osteogenic differentiated canine (xenogeneic) and guinea pig (allogeneic) BMSCs in fracture healing using guinea pig as a model.

Materials And Methods: A well-characterized homogenous population of third passage mesenchymal stem cells of bone marrow origin was used in all the experiments. MSCs from both the species, i.

Smad4 and γ-secretase knock-down effect on osteogenic differentiation mediated via Runx2 in canine mesenchymal stem cells.

Cell lineage determination during mesenchymal stem cell (MSCs) differentiation is a highly orchestrated process involving diverse signaling pathways and distinct classes of regulatory molecules. Bone morphogenetic protein (BMP) signaling positively influence the osteoblast lineage determination, whereas the Notch signaling may have a dimorphic action. Effective regenerative therapy for repairing bone defects requires ample knowledge of the signaling pathways responsible for the differentiation of MSCs.

Expression profile of adhesion molecules in blastocyst vis-a-vis uterine epithelial cells.

Models using in vitro produced buffalo embryos and in vitro cultured uterine epithelial cells (UECs) may be useful in understanding the intricacies of embryo-uterine cross talk. In the present study, buffalo UECs were obtained from slaughterhouse derived non-gravid uterus. UECs monolayer was treated with steroids (10pg/ml estradiol for 24h and 3.

Progesterone modulates adhesion molecules in uterine epithelial cells and in vitro embryo production in buffalo.

This study was undertaken to evaluate the role of progesterone (P4) in modulation of the expression profile of adhesion-related molecules in uterine epithelial cells (UECs) and in vitro blastocyst production in buffalo. UECs were isolated from slaughterhouse-derived uteri by enzymatic treatment, and cells were characterized by immunocytochemistry (ICC) and PCR assays. The well-characterized UECs were exposed to different concentrations of P4 (0, 0.

Effect of cryopreservation on therapeutic potential of canine bone marrow derived mesenchymal stem cells augmented mesh scaffold for wound healing in guinea pig.

The objective of this study was to compare the therapeutic potential of canine bone marrow derived mesenchymal stem cells (BM MSCs) augmented mesh scaffold for wound healing potential in guinea pig before and after cryopreservation. Bone marrow aspirate was obtained from healthy dogs and culture was expanded in vitro. MSCs augmented mesh scaffold were cryopreserved for 30 days and then used for therapeutic purposes.
