Special Issue Information

Dear Colleagues,

By now, most of mankind accepts living in the era of technology, which boasts benefits in terms of goods, spaces, freedom, and certainly an improved quality of life.

Among the technologies available, micro- and nano-technology (MNT) includes solutions as devices, materials, and methods ranging from nanometers to microns. Innovations in MNT have allowed for surprising outcomes in the resolution of serious and long-standing unresolved issues for tissue engineering, theranostics, and drug delivery applications. Micro- and nano-structured lab-on-chips, smart hybrid devices, and a wide collection of drug delivery solutions, including extracellular vesicles, liposomes, microemulsions, nanoparticles, and quantum dots, undoubtedly need precise, reliable, and reproducible biomedical validation certifying their effectiveness and healthiness before their application in diagnostic and/or clinical contests. In vitro and in vivo studies are used the most for MNT validation. Although in vivo experiments are widely used for radiology, nuclear medicine, medical imaging, acute toxicity, and reproductive and developmental toxicity assays, every scientist should keep in mind the fundamental principles of the 3Rs (replacement, reduction, and refinement) proposed by Russel and Burch in 1959. In this perspective, substantial reductions in animal use in research can be achieved by improving in vitro study designs and combining new in silico solutions with high throughput “omics” approaches. The newest in vitro testing solutions include models for several human anatomical districts, such as the blood–brain barrier, placenta, kidneys, lungs, and skin, as well the organ-on-a-chip microfluidic systems, and can be considered ethical, quick, and in many cases cheaper alternatives to in vivo testing. Although they are not alone, they are certainly the first to represent fast and versatile systems to verify the cytotoxicity, hemocompatibility, and efficacy of a whole series of micro- and nano-devices born from the collaboration between medical physicists, chemical engineers, biologists, and clinicians.

In light of the above, this Special Issue of Cells will consist of a selection of high-level research articles, reviews, and communications focusing on the various in vitro systems used for the biomedical validation of the latest innovative micro- and nano-technology solutions.

Stimuli-responsive drug-delivery systems (DDSs) have emerged as a potential tool for applications in healthcare, mainly in the treatment of cancer where versatile nanocarriers are co-triggered by endogenous and exogenous stimuli. Two-dimensional (2D) cell cultures are the most important in vitro model used to evaluate the anticancer activity of these stimuli-responsive DDSs due to their easy manipulation and versatility. However, some limitations suggest that these in vitro models poorly predict the outcome of in vivo studies. One of the main drawbacks of 2D cell cultures is their inadequate representation of the 3D environment’s physiological complexity, which sees cells interact with each other and the extracellular matrix (ECM) according to their specific cellular organization. In this regard, 3D cancer models are a promising approach that can overcome the main shortcomings of 2D cancer cell cultures, as these in vitro models possess many peculiarities by which they mimic in vivo tumors, including physiologically relevant cell–cell and cell–ECM interactions. This is, in our opinion, even more relevant when a stimuli-responsive DDS is being investigated. In this review, we therefore report and discuss endogenous and exogenous stimuli-responsive DDSs whose effectiveness has been tested using 3D cancer cell cultures. Full article
