Objective

The aim of this study was to investigate PDGF release in the peripheral circulation following trauma and to correlate it with the numbers of MSCs in iliac crest bone marrow (BM) aspirate.

Methods

Trauma patients with lower extremity fractures (n=18, age 21–64 years) were recruited prospectively. Peripheral blood was obtained on admission, and at 1, 3, 5 and 7 days following admission. The serum was collected and PDGF was measured using ELISA. Iliac crest (BM) aspirate (20ml) was obtained on days 0–9 following admission. MSCs were enumerated using standard colony-forming unit fibroblasts (CFU-F) assay.
