Abstract
Titanium dental implants are commonly used due to their biocompatibility and biochemical properties; blasted acid-etched Ti is used more frequently than smooth Ti surfaces. In this study, physico-chemical characterisation revealed important differences in roughness, chemical composition and hydrophilicity, but no differences were found in cellular in vitro studies (proliferation and mineralization). However, the deposition of proteins onto the implant surface might affect in vivo osseointegration. To test that hypothesis, protein layers formed on discs of both surface type after incubation with human serum were analysed. Using mass spectrometry (LC/MS/MS), 218 proteins were identified, 30 of which were associated with bone metabolism. Interestingly, Apo E, antithrombin and protein C adsorbed mostly onto blasted and acid-etched Ti, whereas the proteins of the complement system (C3) were found predominantly on smooth Ti surfaces. These results suggest that physico-chemical characteristics could be responsible for the differences observed in the adsorbed protein layer.

Abstract
The myeloid progenitor cell compartment (MPC) exhibits pronounced expansion in human myeloid leukemias. It is becoming more apparent that progression of myelodysplastic syndromes and myeloproliferative diseases to acute myelogenous leukemia is the result of defects in progenitor cell maturation. The MPC of bone marrow was analyzed in mice using a cell culture assay for measuring the relative frequency of proliferative myeloid progenitors. Response to the cytokines SCF, IL-3, and GM-CSF was determined by this assay for the leukemic mouse strain BXH-2 and ten other inbred mouse strains. Significant differences were found to exist among ten inbred mouse strains in the nature of their MPC in bone marrow, indicating the presence of genetic polymorphisms responsible for the divergence. The SWR/J and FVB/J strains show consistently low frequencies of myeloid progenitors, while the DBA/2J and SJL/J inbred strains show consistently high frequencies of myeloid progenitors within the bone marrow compartment. In addition, in silico linkage disequilibrium analysis was conducted to identify possible chromosomal regions responsible for the phenotypic variation. Given the importance of this cell compartment in leukemia progression and the soon to be released genomic sequence of 15 mouse strains, these differences may provide a valuable tool for research into leukemia.
