Project Description

The role of lipid metabolism in a number of cellular processes including (i) stem cell differentiation, (ii) drugcell interactions and (iii) epithelial/adipocyte cell interactions, is generally poorly understood. For example it has been recently shown that PC3 cells when co-cultured with adipocyte cells, sequestrate omega-6 lipids and their metabolites which subsequently stimulate cell migration and whilst promoting proliferation [1]. Similarly lipids have been shown to play a key role in the differentiation of stem-cells, and recent investigations using FTIR have shown that lipid signatures may indicate early signs of differentiation [2]. These fundamental cell processes, mediated by lipids, are currently a major focus of research.

We propose to use Fourier Transform Infrared (FTIR) hyperspectral imaging, high resolution Raman imaging and time of flight-secondary ion mass spectrometry (ToF-SIMS) alongside established co-culture protocols to examine the role of lipids and their metabolites in cells. FTIR imaging of cells has become possible through the recent development of scatter correction algorithms [3]. In addition, the evolution of new high magnification optics coupled with an array detector means that for the first time infrared hyperspectral images with similar pixel resolution similar to that of Raman and ToF-SIMS can be obtained. This means that full multimodal chemical image characterisation can be achieved. The new state of the art Raman system was funded through the BBSRC and has a spatial resolution that spans that of the FTIR and SIMS. The ToF-SIMS instrument developed in Manchester also has unique capabilities in the UK [4,5]. This multimodal imaging approach will facilitate unique lipidomic studies of cellular systems.
