While it has been proved that centrifugal conditions for pure platelet-rich
plasma (P-PRP) preparation influence the cellular composition of P-PRP obtained,
the optimal centrifugal conditions to prepare P-PRP have not yet been identified.
In the present study, platelet-containing plasma (PCP) was prepared with the
first-spin of different double-spin methods and P-PRP was prepared with different
double-spin methods. Whole-blood analysis was performed to evaluate the cellular
composition of PCP and P-PRP. The basal and ADP-induced CD62P expression rates of
platelets were assessed by flow cytometry to evaluate the function of platelets
in PCP and P-PRP. Enzyme-linked immune sorbent assay was performed to quantify
interleukin-1?, tumor necrosis factor-?, platelet-derived growth factor AB and
transforming growth factor ?1 concentrations of PCP and P-PRP. Correlations
between the cellular characteristics and cytokine concentrations of P-PRP were
analyzed by Pearson correlation analysis. Effects of P-PRP on the proliferation,
survival and migration of human bone marrow-derived mesenchymal stem cells and
human articular chondrocytes were evaluated by a Cell Counting Kit-8 assay,
live/dead staining and Transwell assay, respectively. The results showed that
centrifugation at 160 × g for 10 min and 250 × g for 15 min successively captured
and concentrated platelets and growth factors significantly more efficiently with
preservation of platelet function compared with other conditions (P<0.05). The
correlation analysis showed that the similar leukocyte concentrations and
leukocyte-reducing efficiencies resulted in similar pro-inflammatory cytokine
concentrations in P-PRP (P>0.05) and the maximization of platelet concentration,
platelet enrichment factor, platelet capture efficiency and platelet function
resulted in the maximization of growth factor concentrations in P-PRP obtained
using the optimal conditions (P<0.05). Compared with P-PRP obtained under other
conditions, P-PRP obtained under the optimal conditions significantly promoted
the proliferation and migration of cells (P<0.05) and did not alter cell survival
(P>0.05). Therefore, centrifugation at 160 × g for 10 min and 250 × g for 15 min
successively with removal of the buffy coat as a crucial step may provide an
optimal preparation system of P-PRP for clinical application.
