Abstract:

BACKGROUND: Platelet-rich plasma contains a variety of stimulating factors, and can also raise the proteoglycan and collagen synthesis.

OBJECTIVE: To observe the effect of platelet-rich plasma on the proliferation of goat bone marrow mesenchymal stem cells.
METHODS: Blood samples were extracted from the jugular vein of Inner Mongolia Ximeng goats to harvest platelet-rich plasma using centrifugation method. Then, bone marrow was extracted from the goat’s ilium by puncture method to isolate and purify goat bone marrow mesechymal stem cells using density gradient centrifugation method. After that, primary cells at good state were cultured in L-DMEM complete medium containing 10%, 20%, 30% platelet-rich plasma or in simple L-DMEM complete medium.
RESULTS AND CONCLUSION: Within 2-6 days of culture, cells in the platelet-rich plasma groups proliferated faster than those in the control group, and with the increasing of platelet-rich plasma concentration, the cells grew faster, with larger number and more mature morphology. At 4 days of culture, the cell doubling time was about 50, 35, 25 hours in the 10%, 20%, and 30% platelet-rich plasma groups, respectively. These findings indicate that goat platelet-rich plasma can dramatically promote the proliferation of bone marrow mesenchymal stem cells in a concentration-dependent manner.
