Multimodal imaging to study the morphochemistry of basal cell carcinoma

Abstract

Basal cell carcinoma is the most abundant malignant neoplasm in humans, the pathology of which is characterized by an abnormal proliferation of basal cells. Basal cell carcinoma can show a variety of different morphologies, which are based on different cellular biology. Furthermore, the carcinoma often grows invisibly to the eye imbedded in the surrounding skin. Therefore, in some cases its clinical detection is challenging. Thus, our work aims at establishing an unsupervised tissue classification method based on multimodal imaging and the application of chemometrics to discriminate basal cell carcinoma from non‐diseased tissue. A case study applying multimodal imaging to ex‐vivo sections of basal cell carcinoma is presented. In doing so, we apply a combination of various linear and non‐linear imaging modalities, i.e. fluorescence, Raman and second‐harmonic generation microscopy, to study the morphochemistry of basal cell carcinoma. The joint information content obtained by such multimodal approach in studying various aspects of the malignant tissue alterations associated with basal cell carcinoma is discussed.

Is it possible to consider «kinetomics» and «argyromics» as novel trends of functional morphology and systems biology of parasitic and nonparasitic protozoa? a brief analytical review

“…According to the hypothesis of colocalization microchemistry of the analyzed indicators, the cell components and the property / activity maps with the involved systems biology descriptors and pathways (Gradov, 2014;Orehov, 2014;Orehov, 2016) which form the basis of the "omics" targets, it is of great interest to consolidate the above listed descriptors using the principles of multimodal imaging morphochemistry (Vogler, 2010) and morphophysiology (Welsh, 1994). Thus one can speak about the morphochemistry-based "omic", when the physiological and biochemical basis of ROI is taken into account and considered in the frame of the methodologies and techniques of systems biology.…”

Multimodal nonlinear microscopy: A powerful label-free method for supporting standard diagnostics on biological tissues

“…3(c)]. 118 In particular, the amount of fat-rich cells in BCC tissue is signi¯cantly high. The authors hypothesize that the role of these cells is to provide nutrition for proliferating cells, even if this¯nding is not veri¯ed yet.…”

The New Digital Pathology: Just Say NLO

“…In particular, while TPF reveals the distribution of endogenous fluorophores such as NADH, flavins, elastin, and others, SHG microscopy offers direct highresolution imaging of collagen structures, although vibrational techniques enable more detailed characterization of the chemical-molecular composition of the tissue under investigation. Hence, the combination of the above-mentioned microscopic techniques has the potential to provide morphological and chemical information in tandem, realizing a morpho-chemical characterization of a biological specimen [10]. The advantages of having such technologically advanced diagnostic tools can reduce healthcare costs by reducing interpretation time while providing more accurate diagnosis.…”
