Smart City Governance - AI Ethics in a Spatial Context : Select papers from 2021/2022
This brief anthology presents the basics of the interdisciplinary course called “Smart City Governance – AI Ethics in a Spatial Context”, given at Lund University. Furthermore, it includes three papers and a task written by students from the class of 2021/2022 in order to show examples of the topics possible to analyse when combining engineering students from programmes on data, ICT and land surve
Synthesis, characterization, and challenges faced during the preparation of zirconium pillared clays
In this study, Zr-pillared montmorillonite clays (Zr-PILCs) were synthesized using two different precursor materials: raw montmorillonite (CM) and sodium ion-saturated montmorillonite (Na-CM) at different Zr/clay ratios (2.5, 5 and 10 mmol/g). To study the effect of Zr concentration and clay pre-treatment with NaCl on pillaring, the modified clay samples were characterized in detail using X-ray di
Coherently strained and dislocation-free architectured AlGaN/GaN submicron-sized structures
To improve the performance and efficiency of Al containing III-Nitride-based devices, a number of issues must be addressed, especially the presence and generation of dislocations and other structural defects. The main sources of the dislocations are growth on non-native substrates and heteroepitaxial growth of lattice-mismatched layers. We demonstrate the ability to completely avoid structural def

A hyperpromiscuous antitoxin protein domain for the neutralization of diverse toxin domains
Toxin-antitoxin (TA) gene pairs are ubiquitous in microbial chromosomal genomes and plasmids as well as temperate bacteriophages. They act as regulatory switches, with the toxin limiting the growth of bacteria and archaea by compromising diverse essential cellular targets and the antitoxin counteracting the toxic effect. To uncover previously uncharted TA diversity across microbes and bacteriophag

In vitro biomimetic engineering of a human hematopoietic niche with functional properties
In adults, human hematopoietic stem and progenitor cells (HSPCs) reside in the bone marrow (BM) microenvironment. Our understanding of human hematopoiesis and the associated niche biology remains limited, due to human material accessibility and limits of existing in vitro culture models. The establishment of an in vitro BM system would offer an experimentally accessible and tunable platform to stu
Engineered humanized bone organs maintain human hematopoiesis in vivo
Hematopoietic stem cells (HSCs) are maintained in a specialized bone marrow (BM) environment, the so-called HSC niche, that provides pivotal factors for their maintenance. Although the cellular and molecular components of the mouse BM HSC niche have been extensively studied using genetically modified animals, relatively little is known about the counterpart human BM niche components. We previously
Mouse and human HSPC immobilization in liquid culture by CD43- or CD44-antibody coating
Keeping track of individual cell identifications is imperative to the study of dynamic single-cell behavior over time. Highly motile hematopoietic stem and progenitor cells (HSPCs) migrate quickly and do not adhere, and thus must be imaged very frequently to keep cell identifications. Even worse, they are also flushed away during medium exchange. To overcome these limitations, we tested antibody c
Engineered extracellular matrices as biomaterials of tunable composition and function
Engineered and decellularized extracellular matrices (ECM) are receiving increasing interest in regenerative medicine as materials capable to induce cell growth/differentiation and tissue repair by physiological presentation of embedded cues. However, ECM production/decellularization processes and control over their composition remain primary challenges. This study reports engineering of ECM mater
Fat-Derived Stromal Vascular Fraction Cells Enhance the Bone-Forming Capacity of Devitalized Engineered Hypertrophic Cartilage Matrix
Engineered and devitalized hypertrophic cartilage (HC) has been proposed as bone substitute material, potentially combining the features of osteoinductivity, resistance to hypoxia, capacity to attract blood vessels, and customization potential for specific indications. However, in comparison with vital tissues, devitalized HC grafts have reduced efficiency of bone formation and longer remodeling t
Osteoinductivity of engineered cartilaginous templates devitalized by inducible apoptosis.
The role of cell-free extracellular matrix (ECM) in triggering tissue and organ regeneration has gained increased recognition, yet current approaches are predominantly based on the use of ECM from fully developed native tissues at nonhomologous sites. We describe a strategy to generate customized ECM, designed to activate endogenous regenerative programs by recapitulating tissue-specific developme
Combination of immortalization and inducible death strategies to generate a human mesenchymal stromal cell line with controlled survival
The hTERT-immortalization of human bone marrow-derived Mesenchymal Stromal Cells (hMSCs) was proposed to address availability/standardization issues for experimental or clinical studies, but raised concerns due to possible uncontrolled growth or malignant cell transformation. Here we report a method to generate a hMSCs line with controlled survival, through the implementation of a pre-established
