Abstract
Astaxanthin (AXT) is a lipophilic antioxidant and anti-inflammatory natural pigment whose cellular uptake and bioavailability could be improved via liposomal encapsulation. Endothelial cells (EC) line the lumen of all blood vessels and are tasked with multiple roles toward maintaining cardiovascular homeostasis. Endothelial dysfunction is linked to the development of many diseases and is closely interconnected with oxidative stress and vascular inflammation. The uptake of free and liposomal AXT into EC was investigated using Raman and fluorescence microscopies. AXT was either encapsulated in neutral or cationic liposomes. Enhanced uptake and anti-inflammatory effects of liposomal AXT were observed. The anti-inflammatory effects of liposomal AXT were especially prominent in reducing EC lipid unsaturation, lowering numbers of lipid droplets (LDs), and decreasing intercellular adhesion molecule 1 (ICAM-1) overexpression, which is considered a well-known marker for endothelial inflammation. These findings highlight the benefits of AXT liposomal encapsulation on EC and the applicability of Raman imaging to investigate such effects.

Abstract
Abstract
Since the early days of the synthetic lethality concept in DNA Damage Response the status of homologous recombination (HR) repair in cancer cells have been the focus of attention of researchers and clinicians. While different approaches exist, such as the RAD51 immunofluorescence (IF) or HRD genomic assays, functional biomarkers that can assess HR proficiency are missing. We report here the development, optimization and validation of two complementary, HR-specific functional assays. The assays, which are based on the STRIDE platform technology, detect double-strand DNA breaks localized in close proximity to RPA or RAD51 proteins. The optimization phase of assay development was performed in U2OS cells. First, repeatability (intra-run variation) and reproducibility (inter-run variation) of the assays were measured in untreated cells. Then, a series of technical negative controls was performed which have shown that the number of false-positive readouts is below 10% of the total number of signals. Finally, treatment of cells with compounds known to induce double-strand DNA breaks (etoposide and cisplatin) resulted in statistically significant increase in the number of detected dSTRIDE-RAD51 and dSTRIDE-RPA foci when compared to untreated controls. The assays were further validated in NCI-H661 (BRCA2 wild-type) and NCI-H169 (BRCA2 KO) cell line pair. The cells were treated with two concentrations of etoposide and the readouts from dSTRIDE, detecting the total pool of DSBs and dSTRIDE-HR assays were compared. In NCI-H661 cells, treatment with etoposide resulted in an increase in the number of double-strand breaks detected by dSTRIDE and as expected, more DSBs were formed after treatment with the higher concentration. dSTRIDE-HR assays confirmed that approximately 15% and 10% of these DSBs contain RPA and RAD51 proteins, respectively. In NCI-H169 cells etoposide produced a stronger reaction with even more DSBs detected by dSTRIDE, but importantly, no increase in the number of dSTRIDE-RAD51 foci was observed. dSTRIDE-RPA foci increased after treatment hinting that this step of HR remains unperturbed. Interestingly, the number of dSTRIDE-RAD51 foci in untreated cells was comparable between the two cell lines. In conclusion, we show here that two newly developed dSTRIDE-HR assays are well validated and can be successfully applied to report on the status of homologous recombination repair in different cell models.

Abstract
The role of mitochondria goes beyond their capacity to create molecular fuel and includes e.g. the production of reactive oxygen species and the regulation of cell death. In endothelial cells, mitochondria have a significant impact on cellular function under both healthy and pathological conditions. Endothelial dysfunction contributes to the development of various lifestyle diseases and the key players in their pathogenesis are among others vascular inflammation and oxidative stress. The latter is very closely related to mitochondrial dysfunction; however, it is not straightforward. First, because mitochondria are small cellular structures, and second, it requires a sensitive method to follow the subtle biochemical changes. For this purpose, Raman microscopy (RM) was used here, which is considered a high-resolution method and can be applied in situ, usually as a non-labeled technique. In this work, we show that RM can not only locate mitochondria in the cell but also track their functional changes. Moreover, we test if labeling cells with Raman probes (Rp) can improve the specificity and sensitivity of RM (compared to conventional labeled techniques such as fluorescence, and the non-labeled Raman technique). MitoBADY Rp was used to detect changes in mitochondrial membrane potential as an indicator of mitochondrial activity, e.g. hyperpolarization or distortion of the proton gradient in the intermembrane space (depolarization). Thus, we show and compare RM, in the form of a label and non-labeled, to such a subtle cellular analysis.

Abstract
Endothelial cells line the lumen of all vessels in the body and maintain vascular homeostasis. In particular, endothelial cell regeneration in response to insult sustain functional endothelial layer. EdU (5-ethynyl-2'-deoxyuridine) is an alkyne-tagged proliferation probe that incorporates into newly synthesized DNA and is used for fluorescence imaging of cell proliferation with the use of "click chemistry" reaction with a fluorescent azide. Here, we utilized EdU as a click-free Raman probe for tracking endothelial cell proliferation. Raman imaging of EdU was performed in live endothelial cells, showing an advantage over fluorescence imaging of EdU, as this technique did not require sample fixation and permeabilization. To validate Raman-based imaging of EdU to study endothelial cell proliferation, we showed that when endothelial cells were treated with cycloheximide or doxorubicin to impair the proliferation of endothelial cells, the Raman-based signal of EdU was diminished. Furthermore, endothelial cells proliferation detected using EdU-labelled Raman imaging was compared with fluorescence imaging. Finally, the method of Raman-based EdU imaging was used in the isolated murine aorta ex vivo. Altogether, our results show that Raman-based imaging of EdU provides a novel alternative for fluorescence-based assay to assess endothelial proliferation and regeneration.

Abstract
In this review, we present a summary of the basics of the Stimulated Raman Scattering (SRS) phenomenon, methods of detecting the signal, and collection of the SRS images. We demonstrate the advantages of SRS imaging, and recent developments, but also the limitations, especially in image capture speeds and spatial resolution. We also compare the use of SRS microscopy in biological system studies with other techniques such as fluorescence microscopy, second-harmonic generation (SHG)-based microscopy, coherent anti-Stokes Raman scattering (CARS), and spontaneous Raman, and we show the compatibility of SRS-based systems with other discussed methods. The review is also focused on indicating innovations in SRS microscopy, on the background of which we present the layout and performance of our homemade setup built from commercially available elements enabling for imaging of the molecular structure of single cells over the spectral range of 800-3600 cm-1. Methods of image analysis are discussed, including machine learning methods for obtaining images of the distribution of selected molecules and for the detection of pathological lesions in tissues or malignant cells in the context of clinical diagnosis of a wide range of diseases with the use of SRS microscopy. Finally, perspectives for the development of SRS microscopy are proposed.

Abstract
Endothelial cells (EC) in vivo buffer and regulate the transfer of plasma fatty acid (FA) to the underlying tissues. We hypothesize that inflammation could alter the functionality of the EC, i.e., their capacity and uptake of different FA. The aim of this work is to verify the functionality of inflamed cells by analyzing their ability to uptake and accumulate exogenous saturated FA. Control and inflammatory human microvascular endothelial cells stimulated in vitro with two deuterium-labeled saturated FA (D-FA), i.e., palmitic (D31-PA) and myristic (D27-MA) acids. Cells were measured both by spontaneous and stimulated Raman imaging to extract detailed information about uptaken FA, whereas coherent anti-Stokes Raman scattering and fluorescence imaging showed the global content of FA in cells. Additionally, we employed atomic force microscopy to obtain a morphological image of the cells. The results indicate that the uptake of D-FA in inflamed cells is dependent on their concentration and type. Cells accumulated D-FA when treated with a low concentration, and the effect was more pronounced for D27-MA, in normal cells, but even more so, in inflamed cells. In the case of D31-PA, a slightly increased uptake was observed for inflamed cells when administered at higher concentration. The results provide a better understanding of the EC inflammation and indicate the impact of the pathological state of the EC on their capacity to buffer fat. All the microscopic methods used showed complementarity in the analysis of FA uptake by EC, but each method recognized this process from a different perspective.

Abstract
Small molecules are frequently used as dyes, labels and markers to visualize and probe biophysical processes within cells. However, very little is generally known about the light-driven excited-state reactivity of such systems when placed in cells. Here an experimental approach to study ps time-resolved excited state dynamics of a benchmark molecular marker, astaxanthin, in live human cells is introduced.

Abstract
Raman imaging using molecular reporters is a relatively new approach in subcellular investigations. It enables the visualization of organelles in cells with better selectivity and sensitivity compared to the label-free approach. Essentially Raman reporters possess in their structure an alkyne molecular group that can be selectively identified in the spectral region silent for biomolecules, hence facilitate the localization of individual organelles. The aim of this work is to visualize the main cell organelles in endothelial cells (HMEC-1) using established reporters (EdU and MitoBADY), but also to test a new one, namely falcarinol, which exhibits lipophilic properties. Moreover, we tested the possibility to use Raman reporters as a probe to detect changes in distribution of certain organelles after induced endothelial dysfunction (ED) in in vitro models. In both cases, induced ED is characterized by the formation of lipid droplets in the cells, which is why a good tool for the detection of lipid-rich organelles is so important in these studies. Two-dimensional Raman images were obtained, visualizing the distribution of selected organic compounds in the cell, such as proteins, lipids, and nucleic acids. Additionally, the distribution of EdU, MitoBADY and falcarinol in endothelial cells (ECs) was determined. Moreover, we highlight some drawback of established Raman reporter and the need for testing them in various physiological state of the cell.

Abstract
![]()
Multiple diseases are at some point associated with altered endothelial
function, and endothelial dysfunction (ED) contributes to their pathophysiology.
Biochemical changes of the dysfunctional endothelium are linked to
various cellular organelles, including the mitochondria, endoplasmic
reticulum, and nucleus, so organelle-specific insight is needed for
better understanding of endothelial pathobiology. Raman imaging, which
combines chemical specificity with microscopic resolution, has proved
to be useful in detecting biochemical changes in ED at the cellular
level. However, the detection of spectroscopic markers associated
with specific cell organelles, while desirable, cannot easily be achieved
by Raman imaging without labeling. This critical review summarizes
the current advances in Raman-based analysis of ED, with a focus on
a new approach involving molecular Raman reporters that could facilitate
the study of biochemical changes in cellular organelles. Finally,
imaging techniques based on both conventional spontaneous Raman scattering
and the emerging technique of stimulated Raman scattering are discussed.

Abstract
Endothelial cells (EC) constitute a single layer of the lining of blood vessels and play an important role in maintaining cardiovascular homeostasis. Endothelial dysfunction has been recognized as a primary or secondary cause of many diseases and it manifests itself, among others, by increased lipid content or a change in the lipid composition in the EC. Therefore, the analysis of cellular lipids is crucial to understand the mechanisms of disease development. Tumor necrosis factor alpha (TNF-α)-induced inflammation of EC alters the lipid content of cells, which can be detected by Raman spectroscopy. By default, lipid detection is carried out in a label-free manner, and these compounds are recognized based on their spectral profile characteristics. We consider (3S,3'S)-astaxanthin (AXT), a natural dye with a characteristic resonance spectrum, as a new Raman probe for the detection of lipids in the EC of various vascular beds, i.e., the aorta, brain and heart. AXT colocalizes with lipids in cells, enabling imaging of lipid-rich cellular components in a time-dependent manner using laser power 10 times lower than that commonly used to measure biological samples. The results show that AXT can be used to study lipids distribution in EC at various locations, suggesting its use as a universal probe for studying cellular lipids using Raman spectroscopy. The use of labeled Raman imaging of lipids in the EC of various organs could contribute to their easier identification and to a better understanding of the development and progression of various vascular diseases, and it could also potentially improve their diagnosis and treatment.

Abstract
The variable configuration of Raman spectroscopic platforms is one of the major obstacles in establishing Raman spectroscopy as a valuable physicochemical method within real-world scenarios such as clinical diagnostics. For such real world applications like diagnostic classification, the models should ideally be usable to predict data from different setups. Whether it is done by training a rugged model with data from many setups or by a primary-replica strategy where models are developed on a 'primary' setup and the test data are generated on 'replicate' setups, this is only possible if the Raman spectra from different setups are consistent, reproducible, and comparable. However, Raman spectra can be highly sensitive to the measurement conditions, and they change from setup to setup even if the same samples are measured. Although increasingly recognized as an issue, the dependence of the Raman spectra on the instrumental configuration is far from being fully understood and great effort is needed to address the resulting spectral variations and to correct for them. To make the severity of the situation clear, we present a round robin experiment investigating the comparability of 35 Raman spectroscopic devices with different configurations in 15 institutes within seven European countries from the COST (European Cooperation in Science and Technology) action Raman4clinics. The experiment was developed in a fashion that allows various instrumental configurations ranging from highly confocal setups to fibre-optic based systems with different excitation wavelengths. We illustrate the spectral variations caused by the instrumental configurations from the perspectives of peak shifts, intensity variations, peak widths, and noise levels. We conclude this contribution with recommendations that may help to improve the inter-laboratory studies.

Abstract
Excess circulating fatty acids contribute to endothelial dysfunction that subsequently aggravates the metabolic conditions such as fatty liver diseases. However, the exact mechanism of this event is not fully understood, and the investigation on the effect of a direct exposure to fatty acids together with their subsequent fate is of interest. In this work we employed a chemically specific and label-free techniques such as Raman and CARS microscopies, to investigate the process of lipid droplets (LDs) formation in endothelial cells and hepatocytes after exposure to oleic and palmitic acid. We aimed to observe the changes in the composition of LDs associated with metabolism and degradation of lipids. We were able to characterize the diversity in the formation of LDs in endothelium as compared to hepatocytes, as well as the differences in the formation of LDs and degradation manner with respect to the used fatty acid. Thus, for the first time the spectral characteristics of LDs formed in endothelial cells after incubation with oleic and palmitic acid is presented, including the time-dependent changes in their chemical composition.
