Comparative analysis of canine mesenchymal stem cells and bone marrow-derived mononuclear cells.

Background And Aim: Mesenchymal stem cells (MSCs), which have multi-lineage differentiation potentials, are a promising source for regenerative medicine. However, the focus of study of MSCs is shifting from the characterization of the differentiation potential to their secretion potential for cell transplantation. Tissue regeneration and the attenuation of immune responses are thought to be affected by the secretion of multiple growth factors and cytokines by MSCs.

Efficacy of autologous bone marrow mononuclear cell transplantation in dogs with chronic spinal cord injury.

Background: Spinal cord injury (SCI) is relatively common in dogs and is a devastating condition involving loss of sensory neurons and motor neurons. However, the main clinical protocol for the management of SCI is surgery to decompress and stabilize the vertebra. Cell transplantation therapy is a very promising strategy for the treatment of chronic SCI, but extensive preclinical and clinical research work remains.

Lymphokine-activated killer cell transplantation after anti-cancer treatment in two aged cats.

Immunotherapy improves both survival and remission rates after cancer surgery in humans, but its veterinary use has been limited. We determined the safety and feasibility of lymphokine-activated killer (LAK) cell transplantation in two aged cats that had undergone surgery for malignancy. Case 1 involved an 18-year-old male Japanese domestic cat.

Escherichia coli-derived recombinant human bone morphogenetic protein-2 combined with bone marrow-derived mesenchymal stromal cells improves bone regeneration in canine segmental ulnar defects.

Background: Large bone defects in canines usually require assistance to achieve healing. Implantation of osteoinductive factors can promote bone healing, while transplantation of osteoprogenitor cells can enhance bone regeneration. We hypothesized that implantation of an osteoinductive factor, recombinant human bone morphogenetic protein-2 (rhBMP-2), combined with osteoprogenitor cells, bone marrow-derived mesenchymal stromal cells (BMSCs), would synergistically promote bone healing.

Temporal effects of intramuscular administration of medetomidine hydrochloride or xylazine hydrochloride to healthy dogs on tear flow measured by use of a Schirmer tear test I.

Objective: To determine the temporal effects on tear flow measurements obtained by use of a Schirmer tear test (STT) I after IM administration of various doses of medetomidine or xylazine to healthy dogs.

Animals: 5 healthy purpose-bred male Beagles.

Procedures: Each dog received IM injections of 2.

Genetic variants of the unsaturated fatty acid receptor GPR120 relating to obesity in dogs.

G protein-coupled receptor (GPR) 120 is an unsaturated fatty acid receptor, which is associated with various physiological functions. It is reported that the genetic variant of GPR120, p.Arg270His, is detected more in obese people, and this genetic variation functionally relates to obesity in humans.

Autologous bone marrow mononuclear cell transplant and surgical decompression in a dog with chronic spinal cord injury.

Objectives: In dogs with deep analgesia caused by acute spinal cord injury from thoracolumbar disk herniation, autologous bone marrow mononuclear cell transplant may improve recovery. The purpose of the present study was to evaluate autologous bone marrow mononuclear cell transplant in a dog that had paraplegia and deep analgesia caused by chronic spinal cord injury.

Materials And Methods: Autologous bone marrow mononuclear cell transplant was performed in a dog having paraplegia and analgesia for 3 years that was caused by a chronic spinal cord injury secondary to Hansen type I thoracolumbar disk herniation.

Autotransplanting of bone marrow-derived mononuclear cells for complete cases of canine paraplegia and loss of pain perception, secondary to intervertebral disc herniation.

Objectives: Severe intervertebral disc herniation causes complete paraplegia and loss of pain sensation in canines. The prognosis is poor, even when decompression surgery is performed immediately after onset. Studies suggest that bone marrow-derived mononuclear cells will regenerate the injured spinal cord and restore neurologic function.
