Stain-Free Slide-Free Multiphoton Histopathology of Carcinogenesis and Cancer
Multiphoton microscopy has emerged as a powerful tool for stain-free slide-free histopathology. We have recently demonstrated a fiber-based nonlinear optical microscope that achieves fast and simultaneous visualization of a variety of intrinsic molecular contrasts within live tissue including auto-fluorescence excited by two/three-photon processes and specially structured molecules by second/third harmonic generation. Results from human subjects with and without breast cancer, and a pre-clinical rat mammary tumor model, show that extracellular vesicles (exosomes and microvesicles) may serve as new biomarkers for breast cancer. Real-time videos also demonstrate the versatility of this imaging platform in tracking cellular events, including tumor cell migration and leukocyte activation in living rats with carcinogen-induced mammary tumors.
Histopathology, whether with standard hematoxylin and eosin or special immunohistochemical stains, has been the gold-standard process for the diagnosis of disease. However, due to the intensive time and labor required for the histochemical treatment of the tissue in traditional histopathology, great efforts have been devoted to using label-free optical imaging for the examination of intact biological specimens, even in vivo. By shifting to a new excitation wavelength, our fiber-based multimodal nonlinear optical microscope achieves fast and simultaneous visualization of the rich intrinsic molecular information within fresh human breast tissue.
In addition to the near-real-time visualization of the authentic tumor microenvironment, quantitative analysis of these multi-dimensional datasets was performed in search for more selective clinical biomarkers. Preliminary analysis conducted on fresh human breast tissue obtained from healthy and cancer subjects showed that a significant portion of extracellular vesicles from the tumor micro- and macro-environment have unique optical signatures in comparison with those from healthy subjects, opening investigations of their physiological role in carcinogenesis and their diagnostic value for cancer. Collectively, the potential exists for real-time stain-free in vivohistopathology, promoting imaging-based scientific research, and potentially revealing new image-based biomarkers for diseases such as cancer.

Unraveling the origins of endogenous optical metabolic changes
The ability to monitor subcellular functional and structural changes associated with metabolism is essential for understanding tissue development and disease progression. Metabolic perturbations or dysfunctions often play a critical role in numerous diseases, including cancer, obesity, cardiovascular and neurodegenerative disorders. Established methods to assess metabolic processes are either destructive or require the use of exogenous compounds. However, such approaches are limited in their ability to capture the highly dynamic and heterogeneous nature of metabolic responses. In my plenary presentation, I will explain how a combined use of endogenous two-photon intensity and lifetime based fluorescence measurements enable ways to identify changes in specific metabolic pathways. These functional insights can improve understanding of disease development and drug effects.

Nozomi Nishimura
Department of Biomedical Engineering, Cornell University, USA
Exploring natural behaviors of cells in the wild with in vivo multiphoton microscopy
Two-photon microscopy has become an important tool for experimental biology because it enables the dynamic imaging of cellular structures within a whole, living organism. Recent progress such as novel preparations, three-photon microscopy and third harmonic generation imaging reveal new phenomena in mouse models.About the Speaker
Nozomi Nishimura majored in Physics at Harvard College where she worked with Prof. Eric Mazur on femtosecond laser ablation. In graduate school she became interested in neuroscience and worked with Prof. David Kleinfeld at University of California at San Diego. Although still in the Physics Department, her research focused on studying blood flow in the brain of rodents and developing laser-based models of small stroke. She went to Biomedical Engineering at Cornell in 2006 to do a postdoc with Prof. Chris Schaffer. She became an Assistant Professor in Biomedical Engineering in 2013. At Cornell, current research expands the use of in vivo imaging techniques to study a variety of disorders including Alzheimer's disease, cardiac disease and cancer metastasis. As a postdoc, she was awarded a L'Oreal USA Fellowship for Women in Science, the NIH Ruth L. Kirschstein NRSA Postdoctoral Fellowship, and the American Heart Association Postdoctoral Fellowship and while at UC San Diego, she received a National Science Foundation Graduate Research Fellowship.Kandice Tanner

Using Optical tweezers to probe the role of tissue biophysics in metastasis
Tumor latency and dormancy are obstacles in effective treatment of cancer. In the event of metastastic disease, emergence of a lesion can occur at varying intervals from diagnosis and in some cases following successful treatment of the primary tumor. Genetic factors that drive metastatic progression have been identified, such as those involved in cell adhesion, signaling, extravasation and metabolism. Is there a difference in strategy to facilitate outgrowth? Why is there a difference in latency? One missing cue may be the role of tissue biophysics of the brain microenvironment on the infiltrated cells. Here I discuss using optical tweezer based active microrheology to measure the mechanical cues that may influence disseminated tumor cells in different organ microenvironment. I further discuss in vitro and in vivo preclinical models such as 3D culture systems and zebrafish in efforts of providing novel targeted therapeutics.About the Speaker

Diffuse Optical Monitoring of Biomarkers in Brain and Breast
I will describe our progress applying diffuse optical monitoring techniques to measure hemodynamics, metabolism, and autoregulation in brain and breast tissues. The brain studies demonstrate potential for usage as a bedside treatment management tool in the neuro-ICU, especially for patients with traumatic brain injury and acute stroke; the breast studies demonstrate potential of optical cancer therapy monitoring, especially for patients undergoing neoadjuvant chemotherapy prior to surgery.About the Speaker

Lost in Translation?: Clinical trial challenges across the Globe
Friday, 6 April, 12:00–13:30The Diplomat Beach Resort, Grand Ballroom West
The potential for biophotonics technologies to have transformative clinical impact is clear. However, taking a great idea from the bench to the clinic, and then to market is a complex path to navigate. At this lunch event you will hear from a panel of experts who have taken on this challenge in order to deliver their technologies to those who need them. In particular, we will contrast the differences in design features and deployment strategies needed for technologies targeting markets such as the US and Europe, versus technologies for global health – an area well matched to the unique benefits of biophotonics. There will be ample time for questions, discussion and networking.
