Abstract
BACKGROUND The SARS-CoV-2 pandemic has spurred an unparalleled scientific endeavor to elucidate the virus' structure, infection mechanisms, and pathogenesis. Two-dimensional culture systems have been instrumental in shedding light on numerous aspects of COVID-19. However, these in vitro systems lack the physiological complexity to comprehend the infection process and explore treatment options. Three-dimensional (3D) models have been proposed to fill the gap between 2D cultures and in vivo studies. Specifically, spheroids, composed of lung cell types, have been suggested for studying SARS-CoV-2 infection and serving as a drug screening platform. METHODS 3D lung spheroids were prepared by coculturing human alveolar or bronchial epithelial cells with human lung stromal cells. The morphology, size, and ultrastructure of spheroids before and after SARS-CoV-2 infection were analyzed using optical and electron microscopy. Immunohistochemistry was used to detect spike protein and, thus, the virus presence in the spheroids. Multiplex analysis elucidated the cytokine release after virus infection. RESULTS The spheroids were stable and kept their size and morphology after SARS-CoV-2 infection despite the presence of multivesicular bodies, endoplasmic reticulum rearrangement, tubular compartment-enclosed vesicles, and the accumulation of viral particles. The spheroid responded to the infection releasing IL-6 and IL-8 cytokines. CONCLUSION This study demonstrates that coculture spheroids of epithelial and stromal cells can serve as a cost-effective infection model for the SARS-CoV-2 virus. We suggest using this 3D spheroid as a drug screening platform to explore new treatments related to the cytokines released during virus infection, especially for long COVID treatment.

Abstract
Cell culture under medium flow has been shown to favor human brain microvascular endothelial cells function and maturation. Here a three-dimensional in vitro model of the human brain microvasculature, comprising brain microvascular endothelial cells but also astrocytes, pericytes and a collagen type I microfiber - fibrin based matrix, was cultured under continuous medium flow in a pressure driven microphysiological system (10 kPa, in 60-30 s cycles). The cells self-organized in micro-vessels perpendicular to the shear flow. Comparison with static culture showed that the resulting interstitial flow enhanced a more defined micro-vasculature network, with slightly more numerous lumens, and a higher expression of transporters, carriers and tight junction genes and proteins, essential to the blood-brain barrier functions.

Abstract
Corneal defects due to diabetes mellitus (DM) may cause severe vision impairments. Current studies focus on the corneal epithelium and nerve defects neglecting the corneal stroma. The aim of this study was to develop a 3D in vitro model to examine the interactions between corneal stroma and nerves in the context of DM. Primary human corneal stromal fibroblasts isolated from healthy (HCFs), Type 1 (T1DM) and Type 2 (T2DM) patients were stimulated with stable ascorbic acid to secrete and assemble an extracellular matrix (ECM). Human neuronal cells were then seeded on top and differentiated to create the 3D co-cultures. Our data revealed successful co-culture of stromal fibroblasts and neuronal cells with large elongated neuron extensions. T2DM showed significant upregulation of Collagen III and IGF1 when compared to T1DM. Interestingly, upon nerve addition, those markers returned to HCF levels. Neuronal markers were also differentially modulated with T2DM co-cultures expressing high levels of βIII tubulin where T1DM co-cultures expressed Substance P. . Overall, our unique 3D co-culture model provides us with a tool that can be utilized for both molecular and therapeutic studies for diabetic keratopathy.

Abstract
Formation of new lymphatic vessels, termed lymphangiogenesis, is central for diverse biological processes during development, inflammation and tumor metastasis. However, reliable in vitro model is still under demand for detailed elucidation of how sprouting lymphangiogenesis is initiated and coordinated. Here, we describe a microfluidic platform optimized for close reconstitution of lymphangiogenesis, achieved by on-chip integration of salient constituents of lymphatic microenvironment found in vivo. With flexible and precise control over the factors that include biochemical cues, interstitial flow (IF), and endothelial-stromal interactions, we found that orchestrated efforts of multiple environmental factors are necessary for robust lymphatic sprouting in 3D extracellular matrix. Especially, we demonstrate that IF serves as a central regulatory cue which defines lymphangiogenic responses and phenotypes of lymphatic endothelial cells. When synergized with pro-lymphangiogenic factors, IF significantly augmented initiation and outgrowth of lymphatic sprouts toward upstream of the flow while suppressing downstream-directed sprouting. In an appropriate synergism, lymphatic sprouts exhibited structural, molecular signatures and cellular phenotypes that closely approximate sprouting lymphatic neovessels in vivo, and precisely reflected the modulatory effects of pro- and anti-lymphangiogenic stimuli. Our study not only reveals critical but unappreciated role of mechanical cue that regulates lymphangiogenic sprouting, but also provides a novel biomimetic model that may leverage further biological studies as well as phenotypic drug screening.
