Abstract

Fragmin/protamine nanoparticles (F/P NPs) can be stably coated onto plastic surfaces and used as a substratum for the absorption and controlled release of growth factors (GFs) secreted from human platelet-rich plasma (PRP). In this study, we investigated the capability of F/P NP-coated plates to act as a substratum for the proliferation of human adipose-derived stromal cells (ASCs) and bone marrow-derived mesenchymal stem cells (BMSCs) with GFs in PRP. Both cell types adhered well to the F/P NP-coated plates and grew optimally, with a doubling time of 30 and 32 h in low-concentration PRP (0.5%) medium supplemented with 5 ng/ml fibroblast growth factor-2 (FGF-2) on the F/P NP-coated plates. These cells maintained their multilineage potential for differentiation into adipocytes or osteoblasts. Furthermore, ASCs and BMSCs grew well in medium without PRP and FGF-2 on F/P NP-coated plates pretreated with PRP and FGF-2 in a concentration-dependent manner. Thus, F/P NP-coated plates are a useful substratum for the adherence and proliferation of ASCs and BMSCs in low-concentration PRP medium supplemented with FGF-2. No xenogeneic serum is required.
