Research Expertise
Description
Dr. Monaghan's research focus is the generation of cardiac tissue in vitro towards the purpose of disease modelling and therapeutic transplantation. Heart attacks are an increasing healthcare burden and despite many medical advances, once heart muscle dies following a heart attack it does not heal sufficiently, and becomes scarred, leading to reduced function and quality of health. It is possible to generate new heart muscle from stem cells and more recently from adult cells of the body (e.g. skin cells) but such new heart muscle is not fully functional or mature as it is not experiencing the natural environment of the heart. His research is focused on the use of tunable biomaterial scaffolds using both biomechanical and biomolecular stimuli to mimic the cardiac environment and achieve robust cardiomyocyte transdifferentiation. Dr. Monaghan research interests also include non-invasive microscopy. Multiphoton microscopy is a powerful method for the nondestructive evaluation of deep-tissue, cells and extracellular matrix (ECM) structures. By interacting with highly non-centrosymmetric molecular assemblies, the non-linear phenomenon of second harmonic generation (SHG) has also proven to be an important diagnostic tool for the visualization of collagen and myosin. Multiphoton microscopy can be additionally equipped with time correlated single photon counting boards which allow extensive analysis of the photons being emitted from any material due to excitation by a specific wavelength and provides a photon distribution analysis. Notably, this facilitates fluorescence lifetime imaging (FLIM), which produces images based on the differences in the exponential decay rate of the fluorescence from a fluorescent sample, where the lifetime of a fluorophore signal is used to create the image. This method reduces the effect of photon scattering in thick samples and also avoids sample bleaching and photo-induced toxicity. Investigated fluorophores can be naturally present in the cell (e.g. NAD(P)H, which is indicative of cellular metabolism), or fluorophores that we can introduce externally to understand cell pathways and signaling.

- Cell-Specific Metabolic FLIM Profiling of the Ulcerative Colitis Microenvironment to Establish an Association with Patient Treatment Response
- Summary
- Non-invasive FLIM could reliably establish a statistically significant relationship between the FLIM characteristics of UC biopsies and UC patient response. The specific aims of this research project are to employ FLIM to characterise the microenvironment of lesions in UC. This includes measurement of the mean fluorescent decay times, contributing lifetimes and ratios of NADH and FAD within cellular populations dominating the UC microenvironment in a spatio-temporal manner. This will pave the way towards launching a FLIM imaging core facility that can reliably categorise cell specific metabolic profiles within tissue biopsies from patients diagnosed with UC, and provide recommendations for treatment regimens.
