BM3 Instrumentation Facility Overview

The Biomechanics, Biomaterials and Biomedicine Instrumentation Facility (BM3) is the newest addition to the College of Engineering core research facilities at the University of Nebraska-Lincoln. Located in Room 126A of the Walter Scott Engineering Center (bay area) the facility occupies approximately 1000 sq.ft. of combined laboratory space. The BM3 opened in the summer of 2010 with the mission of providing access to critical research infrastructure to faculty and their collaborators. Please explore our website where you will find more details about each of the instruments currently available in our facility, and how to begin incorporating them in your research.

We hope to see you soon.

Mission Statement

DaVinciMan Our mission is to support interdisciplinary research in the areas embracing biomechanics, biomaterials and biomedicine (the “BM3”) engineering. The BM3will provide engineering faculty and their collaborators with access to the critical research infrastructure that typically lies beyond the reach of an individual or small team of faculty in targeted interdisciplinary areas. The BM3 is intended to support the advancement of all College of Engineering faculty having interests in bio-engineering research, and will not be constrained to any particular department or group. We are making every effort to make these techniques available and affordable to anyone interested.

The BM3 long term goal is to serve as a focal point for collaboration between engineering faculty and researchers in applied fields, such as human and veterinary medicine, dentistry, and pharmaceutics, and will seek to catalyze collaborative opportunities through networking activities. We expect to cooperate with a wide variety of customers from the academic and industrial background and actively participate in developing new research ideas.

BONE FORMATION STIMULATED WITH MECHANICAL LOADING

BioDynamic Chamber BOSE Electroforce 3200 instrument was used to perform dynamic cyclic compression tests on polyurethane open cell foam scaffolds seeded with fully differentiated osteoblastic cells, MLO-A5 line. The results indicate mineralisation (calcium content) and production of biomarkers (type I collagen, osteopontin and osteocalcin) characteristic for bone extracellular matrix (ECM) are highly sensitive towards mechanical stimulation. The compression loading was preformed in situ using commercially available ‘Orthopaedic BioDynamic™ Chamber’ from Bose Electroforce systems group.

COMBINATORIAL CELL CULTURE SYSTEMS ON PATTERNED SURFACES

Patterning Protein microarraying combined with photoresist lithography enabled printing of extracellular matrix (ECM) protein arrays while precisely controlling “on-the-spot” cell-cell interactions. Hepatic cells (HepG2) attached on various diameter spots of collagens I, II, and IV and laminin and were characterized with fluorescence microscopy and AFM. Laser Scanning Cytometer was used to precisely estimate cellular populations attached to protein domains with different sizes. 3T3 fibroblasts subsequently seeded on non-patterned surfaces were used to evaluate coculture conditions.
