Cells were isolated and characterized as undifferentiated mesenchymal cells with a phenotype fibroblasts-like and characteristic phenotype of confirmed by flow cytometry with CD44 +, CD105 +, CD271 +, CD34-and CD45-, plus the ability to differentiate into adipocytes, chondrocytes and osteocytes. Except for the control group (MSCs), in all groups, G-PRP (PRP and MSCs), G-DBM (DBM and MSCs) and G-PRP + DBM (MSCs and PRP + DBM) was differentiation osteoblastic with production of mineralized bone matrix confirmed by Alizarin red staining. The measurement of alkaline phosphatase (AP) increased up to 14 days in all groups. Bone proteins were expressed in the polymerase chain reaction in real time and were able to confirm the differentiation bone in all groups. Osteopontin had its greatest expression in G- PRP to seven days followed by G-PRP + DBM, at other times the G-PRP + DBM had higher expression than the other groups. The osteocalcin and Runx2 were expressed more intensely in the G-PRP + DBM at the end of the experiment. It can be concluded that the PRP and DBM are capable of promoting osteogenesis mesenchymal cells in Wharton's jelly of the umbilical cord with canine, with advantage in the presence of DBM
