Welcome to the Cell and Molecular Biomechanics Lab! CMBL is part of the Department of Biomedical Engineering at Columbia University! The CMBL is focused on determining the mechanism that allows cells to sense and respond to extracellular mechanical stimulation. Particularly we are interested in determining, at a cellular level, how bone tissue is regulated by physical loading. This work has applications in developing new therapies to age-related bone loss and osteoporosis. We explore this question both in cell culture identifying novel molecular targets and in quantifying the skeletal sensitivity to loading of tissue-specific conditional deletions in mice. Our current targets include focal adhesions, cytoskeletal proteins, and the cell's primary cilium.

- 1/16/2010 CMBL Postdoctoral Fellow David Hoey awarded Best Presentation at the 28th meeting of the SPRBM
Postdoctoral fellow David Hoey was awarded best presentation in the Postdoctoral Category at the 28th meeting of the Society of Physical Regulation in Biology and Medicine. His paper was entitled “Determining the mechanisms of primary cilia bending in response to fluid shear stress”. This paper along with fellow CMBL member, graduate student Jennifer Blundo’s paper are available on the SPRBM website (http://www.pitt.edu/~sprbm/index.html)
- 9/1/2009 CMBL Postdoc David Hoey awarded IRCSET-Marie Curie International Mobility Fellowship in Science, Engineering and Technology
The objective of the IRCSET-Marie Curie INSPIRE co-funded Scheme is to encourage Ireland-based researchers to avail of a structured period of overseas mobility with associated career development actions, followed by a corresponding return period in Ireland. David will spend two years here in Columbia University after which he will return to Prof. O’Brien's lab in the Royal College of Surgeons in Ireland (http://www.ircset.ie/Default.aspx?tabid=240)
- 9/1/2009 The CMBL receives New York State Stem Cell Grant
The CMBL was delighted to receive a three year grant to study the role of primary cilia in the ability of bone marrow derived stem cells to sense and respond to mechanical load. The grant, titled "Mechanosensitive primary cilia in osteogenic differentiation of stem cells due to loading" if funded by the New York State Stem Cell Board (NYSTEM). You can look at the lay abstract of the project here.
