Mesenchymal stem cells (MSCs) are adult multipotent cells with fibroblastoid morphology and adherent to plastic. Furthermore, they can be obtained from different sources. Besides bone marrow, these cells are taken from umbilical cord blood, umbilical vein, saphenous vein, peripheral blood, arteries, liver and fetal pancreas, placenta, dental pulp and adipose tissue. MSCs derived from adipose tissue are important because of the abundant number of cells that can be obtained from this tissue, easy access and little discomfort to the patient. This study compared two techniques for obtaining MSCs from adipose tissue: mechanical dissociation (MD) and enzymatic digestion (ED). We also analyzed the inter-species cross-reactions using commercial monoclonal antibodies directed against surface antigens of stem cells from different species: mouse, horse, rabbit, monkey and human. We found that MD technique is favorable in relation to ED within 15 days of culture, and ED is more efficient in the first days of culture. The data also showed that MD causes less damage to cellular DNA. About inter-species cross-reactions, the monoclonal antibody A69 directed against stem cells from rabbits, which can be used in veterinary medicine, particularly in research involving horses

Diabetes Mellitus is caracterized by a disturbance on endocrine pâncreas with reduction in serum levels of insulin. The deficiency or absence of insulin promotes alterations in the metabolism of carbohydrates, lipidis and proteins. The most common clinical signs of disease are polyuria, polydipsia, polyphagia and loses of weight. The diagnosis is made based on clinical symptoms, with laboratory confirmation through persistent hyperglycemia on fasting and glycosuria. Treatment includes insulin therapy, diet, exercise and oral hypoglycemic agents in an attempt to reverse the catabolic effects associated with deficiency or antagonism of insulin and restore normal homeostasis of the metabolism of proteins, lipids and carbohydrates
