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.

Comparative analysis of the immunomodulatory potential of caprine fetal adnexa derived mesenchymal stem cells.

The caprine mesenchymal stem cells (MSCs) derived from fetal adnexa are highly proliferative. These cells possess tri-lineage differentiation potential and express MSC surface antigens and pluripotency markers with a wound-healing potential. This present study was conducted to compare the immunomodulatory potential of caprine MSCs derived from the fetal adnexa.

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.

Isolation and propagation of classical swine fever virus in porcine Wharton's Jelly mesenchymal stem cells.

Classical Swine Fever (CSF) is an extremely infectious and deadly disease of pigs and wild boars caused by the CSF virus (CSFV) which is a member of the Pestivirus genus and the family . This study was designed to detect the permissibility and replication of CSFV in mesenchymal stem cells (MSCs) monolayer derived from Porcine Wharton's jelly. Porcine Wharton's jelly MSCs (pWJ-MSCs) were expanded and propagated for more than 81 generations and third passage pWJ-MSCs were characterized as per standard criteria i.

Effect of roscovitine on developmental competence of small follicle-derived buffalo oocytes.

Background & Objectives: The lower recovery of competent oocytes in buffalo species limits the commercialization of in vitro embryo production technology in field condition. In this context, pre-maturation of small follicle (SF)-derived oocytes with meiotic inhibition may be a promising alternative to obtain more number of competent oocytes. Thus, the present study was conducted with an objective to enhance the developmental potential of less competent SF-derived buffalo oocytes.

An allogenic therapeutic strategy for canine spinal cord injury using mesenchymal stem cells.

This study was conducted to characterize canine bone marrow-derived mesenchymal stem cells (BMSCs); in vivo tracking in mice, and therapeutic evaluation in canine clinical paraplegia cases. Canine BMSCs were isolated, cultured, and characterized in vitro as per International Society for Cellular Therapy criteria, and successfully differentiated to chondrogenic, osteogenic, and adipogenic lineages. To demonstrate the homing property, the pGL4.

Leptin supplementation in vitro improved developmental competence of buffalo oocytes and embryos.

The aim of the present study was to determine potential role of leptin on in vitro developmental competence of buffalo oocytes and embryos. Slaughterhouse derived culture grade buffalo cumulus oocyte complexes (COCs) were matured in vitro (IVM) with leptin (10 ng/ml) or without leptin (control). In each experiment, a pool of matured COCs was used for further in vitro embryo production and another pool of COCs was used for cumulus cells and mature oocytes isolation to study the relative mRNA expression of developmentally important genes.

Impact of oocyte-secreted factors on its developmental competence in buffalo.

Oocyte-secreted factors (OSFs) play an important role in the acquisition of oocyte developmental competence through bidirectional cross-talk between oocyte and cumulus cells via gap junctions. Thus, the present study was designed to investigate the effect of two OSFs, growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15), on the developmental competence of buffalo oocytes derived from two different follicle sizes. Cumulus-oocyte complexes (COCs) from large follicles (LF, >6 mm) or small follicles (SF, 0.

Impact of Cryopreservation on Caprine Fetal Adnexa Derived Stem Cells and Its Evaluation for Growth Kinetics, Phenotypic Characterization, and Wound Healing Potential in Xenogenic Rat Model.

This study was conducted to know the impact of cryopreservation on caprine fetal adnexa derived mesenchymal stem cells (MSCs) on the basic stem cell characteristics. Gravid caprine uteri (2-3 months) were collected from local abattoir to derive (amniotic fluid [cAF], amniotic sac [cAS], Wharton's jelly [cWJ], and cord blood [cCB]) MSCs and expanded in vitro. Cells were cryopreserved at 3rd passage (P3) using 10% DMSO.
