Abstract
The cytosolic delivery of various substrates in 3D multicellular spheroids by thiol-mediated uptake is reported. This is important because most orthodox systems, including polycationic cell-penetrating peptides, fail to deliver efficiently into deep tissue. The grand principles of supramolecular chemistry, that is the pH dependence of dynamic covalent disulfide exchange with known thiols on the transferrin receptor, are proposed to account for transcytosis into deep tissue, while the known but elusive exchange cascades along the same or other partners assure cytosolic delivery in kinetic competition. For quantitative detection in the cytosol, the 2D chloroalkane penetration assay (CAPA) is translated to 3D deep tissue. The targeted delivery of quantum dots, otherwise already troublesome in 2D culture, and the controlled release of mechanophores are realized to exemplify the power of thiol-mediated uptake into spheroids. As transporters, dithiolane quartets on streptavidin templates are introduced as modular motifs. Built from two amino acids only, the varied stereochemistry and peptide sequence are shown to cover maximal functional space with minimal structural change, i.e., constitutional isomers. Reviving a classic in peptide chemistry, this templated assembly of β quartets promises to expand streptavidin biotechnology in new directions, while the discovery of general cytosolic delivery in deep tissue as an intrinsic advantage further enhances the significance and usefulness of thiol-mediated uptake.

Abstract
Selenium is capable of forming a dynamic covalent bond with itself and other elements and can undergo metathesis and regeneration reactions under optimum conditions. Its dynamic nature endows selenium-containing polymers with striking sensitivity towards some environmental alterations. In the past decade, several selenium-containing polymers were synthesized and used for the preparation of oxidation-, reduction-, and radiation-responsive nanocarriers. Recently, thioredoxin reductase, sonication, and osmotic pressure triggered the cleavage of Se-Se bonds and swelling or disassembly of nanostructures. Moreover, some selenium-containing nanocarriers form oxidation products such as seleninic acids and acrylates with inherent anticancer activities. Thus, selenium-containing polymers hold promise for the fabrication of ultrasensitive and multifunctional nanocarriers of radiotherapeutic, chemotherapeutic, and immunotherapeutic significance. Herein, we discuss the most recent developments in selenium-containing polymeric micelles in light of their architecture, multiple stimuli-responsive properties, emerging immunomodulatory activities, and future perspectives in the delivery and controlled release of anticancer agents.

Abstract
The complexity and diversity of the biochemical processes that occur during tumorigenesis and metastasis are frequently over-simplified in the traditional in vitro cell cultures. Two-dimensional cultures limit researchers' experimental observations and frequently give rise to misleading and contradictory results. Therefore, in order to overcome the limitations of in vitro studies and bridge the translational gap to in vivo applications, 3D models of cancer were developed in the last decades. The three dimensions of the tumor, including its cellular and extracellular microenvironment, are recreated by combining co-cultures of cancer and stromal cells in 3D hydrogel-based growth factors-inclusive scaffolds. More complex 3D cultures, containing functional blood vasculature, can integrate in the system external stimuli (e.g. oxygen and nutrient deprivation, cytokines, growth factors) along with drugs, or other therapeutic compounds. In this scenario, cell signaling pathways, metastatic cascade steps, cell differentiation and self-renewal, tumor-microenvironment interactions, and precision and personalized medicine, are among the wide range of biological applications that can be studied. Here, we discuss a broad variety of strategies exploited by scientists to create in vitro 3D cancer models that resemble as much as possible the biology and patho-physiology of in vivo tumors and predict faithfully the treatment outcome.

Abstract
The performance of supramolecular nanocarriers as drug delivery systems depends on their stability in the complex and dynamic biological media. After administration, nanocarriers are challenged by physiological barriers such as shear stress and proteins present in blood, endothelial wall, extracellular matrix, and eventually cancer cell membrane. While early disassembly will result in a premature drug release, extreme stability of the nanocarriers can lead to poor drug release and low efficiency. Therefore, comprehensive understanding of the stability and assembly state of supramolecular carriers in each stage of delivery is the key factor for the rational design of these systems. One of the main challenges is that current 2D in vitro models do not provide exhaustive information, as they fail to recapitulate the 3D tumor microenvironment. This deficiency in the 2D model complexity is the main reason for the differences observed in vivo when testing the performance of supramolecular nanocarriers. Herein, we present a real-time monitoring study of self-assembled micelles stability and extravasation, combining spectral confocal microscopy and a microfluidic cancer-on-a-chip. The combination of advanced imaging and a reliable 3D model allows tracking of micelle disassembly by following the spectral properties of the amphiphiles in space and time during the crucial steps of drug delivery. The spectrally active micelles were introduced under flow and their position and conformation continuously followed by spectral imaging during the crossing of barriers, revealing the interplay between carrier structure, micellar stability, and extravasation. Integrating the ability of the micelles to change their fluorescent properties when disassembled, spectral confocal imaging and 3D microfluidic tumor blood vessel-on-a-chip resulted in the establishment of a robust testing platform suitable for real-time imaging and evaluation of supramolecular drug delivery carrier's stability.

Light sheet fluorescence microscopy versus confocal microscopy: in quest of a suitable tool to assess drug and nanomedicine penetration into multicellular tumor spheroids.

Abstract
We recently constructed a multicellular spheroid model of pancreatic tumor based on a triple co-culture of cancer cells, fibroblasts and endothelial cells and characterized by the presence of fibronectin, an important component of the tumor extracellular matrix. By combining cancer cells and stromal components, this model recreates in vitro the three-dimensional (3D) architecture of solid tumors. In this study, we used these hetero-type spheroids as a tool to assess the penetration of doxorubicin (used as a model drug) through the whole tumor mass either in a free form or loaded into polymer nanoparticles (NPs), and we investigated whether microscopy images, acquired by Confocal Laser Scanning Microscopy (CLSM) and Light Sheet Fluorescence Microscopy (LSFM), would be best to provide reliable information on this process. Results clearly demonstrated that CLSM was not suitable to accurately monitor the diffusion of small molecules such as the doxorubicin. Indeed, it only allowed to scan a layer of 100 µm depth and no information on deeper layers could be available because of a progressive loss of the fluorescence signal. On the contrary, a complete 3D tomography of the hetero-type multicellular tumor spheroids (MCTS) was obtained by LSFM and multi-view image fusion which revealed that the fluorescent molecule was able to reach the core of spheroids as large as 1 mm in diameter. However, no doxorubicin-loaded polymer nanoparticles were detected in the spheroids, highlighting the challenge of nanomedicine delivery through biological barriers. Overall, the combination of hetero-type MCTS and LSFM allowed to carry out a highly informative microscopic assessment and represents a suitable approach to precisely follow up the drug penetration in tumors. Accordingly, it could provide useful support in the preclinical investigation and optimization of nanoscale systems for drug delivery to solid tumors.

Abstract
Gene therapy through systemic administration is expected to offer significant therapeutic potential against intractable cancers, including pancreatic cancer. One of the requirements for in vivo gene therapy is the development of a gene carrier with a high level of safety, transfection ability and tumour accumulation. Bovine serum albumin (BSA)-poly(2-dimethylaminoethyl methacrylate) (PDMAEMA) conjugation (BSA-PDMAEMA conjugation) could result in the development of a promising gene carrier. This conjugate could preserve the BSA structure well and efficiently condense the nucleotide inside, resulting in the formation of BSA-PDMAEMA nanoparticles that have a polyion complex core and surrounding BSA corona with a size of <100 nm. The nanoparticles that were produced based on BSA-PDMAEMA conjugation possessed good characteristics for use as a gene carrier with good biocompatibility, appropriate blood retention and gene protective properties. Furthermore, the in vivo two-dimensional and three-dimensional biodistribution in a xenograft pancreatic cancer (AsPC-1) model in mice clearly showed that BSA-PDMAEMA nanoparticles accumulated at the tumour site via enhanced permeability and the retention effect. Furthermore, BSA-PDMAEMA nanoparticles, which condensed the active anti-cancer oligonucleotide, ISIS5132, inhibited the growth of cancer in AsPC-1-bearing mice compared to mice which were administered with ISIS5132 alone. The structure of the BSA-PDMAEMA nanoparticles, i.e. the polyion complex core with the BSA corona, would comprehensively contribute to these ideal characteristics for use as a gene carrier. In conclusion, BSA-PDMAEMA nanoparticles could exert a therapeutic effect on intractable pancreatic cancer in vivo, indicating their use as a promising gene carrier.

Abstract
The development of smart delivery systems that are robust in circulation and quickly release drugs following selective internalization into target cancer cells is a key to precision cancer therapy. Interestingly, reduction-sensitive polymeric nanomedicines showing high plasma stability and triggered cytoplasmic drug release behavior have recently emerged as one of the most exciting platforms for targeted delivery of various anticancer drugs including small chemical drugs, proteins, and nucleic acids. In vivo studies in varying tumor models reveal that these reduction-sensitive multifunctional nanomedicines outperform the currently used clinical formulations and reduction-insensitive counterparts, bringing about not only significantly enhanced tumor selectivity, accumulation and inhibition efficacy but also markedly reduced systemic toxicity and improved therapeutic index. In this review, we will highlight the cutting-edge advancement with a focus on in vivo performances as well as future perspectives on reduction-sensitive polymeric nanomedicines for targeted cancer therapy.

Abstract
Multicellular tumor spheroid models (MCTS) are often coined as 3D in vitro models that can mimic the microenvironment of tissues. MCTS have gained increasing interest in the nano-biotechnology field as they can provide easily accessible information on the performance of nanoparticles without using animal models. Considering that many countries have put restrictions on animals testing, which will only tighten in the future as seen by the recent developments in the Netherlands, 3D models will become an even more valuable tool. Here, an overview on MCTS is provided, focusing on their use in cancer research as most nanoparticles are tested in MCTS for treatment of primary tumors. Thereafter, various types of nanoparticles-from self-assembled block copolymers to inorganic nanoparticles, are discussed. A range of physicochemical parameters including the size, shape, surface chemistry, ligands attachment, stability, and stiffness are found to influence nanoparticles in MCTS. Some of these studies are complemented by animal studies confirming that lessons from MCTS can in part predict the behaviour in vivo. In summary, MCTS are suitable models to gain additional information on nanoparticles. While not being able to replace in vivo studies, they can bridge the gap between traditional 2D in vitro studies and in vivo models.

Abstract
An effective drug delivery system requires efficient drug uptake and release inside cancer cells. Here, we report a novel drug delivery system, in which paclitaxel (PTX) interacts with a novel cell penetrating peptide (CPP) through noncovalent interaction designed based on molecular simulations. This CPP/PTX complex confers high efficiency in delivering PTX into cancer cells not by endocytosis but by an energy-independent pathway. Once inside cells, the noncovalent interaction between PTX and the CPP may allow fast release of PTX within cells due to the direct translocation of CPP/PTX. This drug delivery system exhibits strong capacity for inhibition of tumor growth and offers a new avenue for the development of advanced drug delivery systems for anticancer therapy.
