Adrenomedullin in dental tissues
Tooth development is complex and dependent on epithelial-mesenchymal interactions involving key molecular signalling pathways. Preliminary data indicate that the pleiotropic growth factor adrenomedullin (ADM) is expressed during tooth development. Furthermore, in osteoblasts, cells which share …

Computational Morphogenesis of City Tissues
Scientific discoveries of the 20th century had a profound impact not only on the study of the natural sciences but disciplines worldwide. The studies were rooted in understanding the complex process of organisation, development and evolution in natural systems before attempting to emulate the …

Morphogenetic signaling in growing tissues
… and sizes. The proper size and patterning of tissues are ensured by signaling molecules as e.g. morphogens. Secreted from a restricted source, morphogens spread into the adjacent target tissue where they form a graded concentration profile. Upon binding of the morphogens to receptors on the …

Modelling Cell Orientation In Artificial Tissues
Engineered tissues have many potential applications both as experimental systems and in therapeutic devices and treatments. Specially, there is potential to repair damaged spinal cord, however work is still needed to predict the process of tissue growth. Computational physics has potential to …

Characterizing optical properties in fibrous tissues
… non-invasive tissue characterization. Biological tissues can be classified into isotropic tissues and anisotropic tissues. The optical properties of isotropic tissues such as adipose tissue are independent of measurement direction. However, optical properties of anisotropic tissues such as tendon …

Mutational processes in normal human tissues
… historical presence of mutational processes in tissues that may be linked to causes of diseases. During my PhD, I first characterised the operating mutational processes in normal human small intestine through extensive sequencing and phylogenetic reconstruction of multiple biopsies from a group …

Positional Information in Adult Bilaterian Tissues
… how positional information functioned in adult tissues more generally in Bilateria. Acoels, a sister clade to the rest of Bilateria, also display a muscle-expressed PCG system that underlies their regenerative ability. This suggests that adult positional information could be evolutionarily …

Hypothermic Machine Perfusion of Composite Tissues
Organ perfusion systems have successfully been applied to solid organ preservation and subsequent transplantation. However, their use in limb preservation for Vascularized Composite Tissue Allotransplantation (VCA) has yet to be thoroughly investigated. This thesis explores the potential for …

Engineered Heart Tissues for Advanced Disease Modeling
… environment to generate engineered heart tissues (EHTs). The EHT platform matures hiPSC-CMs by providing the environmental cues present in the in vivo myocardium while allowing for assessments of cardiac function. Although heart failure is the leading cause of death in patients with …

Dynamics and Mechanics of Zebrafish Embryonic Tissues
… properties of zebrafish embryonic cells and tissues. This thesis is structured as follows: In chapter 2, we introduce the fundamental concepts that are important for the study of cell motion during zebrafish embryonic development. In chapter 3, the materials and methods applied in this work …

The targeting of corticosteroids to inflamed tissues
… to deliver corticosteroids to inflamed tissues by both the oral and intravenous routes. Hydrocortisone (HC)-loaded albumin microspheres were prepared by three different methods, by direct incorporation of HC within the particles, by indirect incorporation of HC by the enzymatic …

Lymphocyte subset variability between human lymphoid tissues
… adaptive immune lymphocytes are in the lymphoid tissues. However, studies of human lymphocytes to date have primarily investigated cells from the blood, and lymphoid tissues remain poorly studied. This thesis explores the hypothesis that there is local variation of B cell subsets between the …

Advanced neural networking and classification techniques for human brain tissues diagnoses: segmenting healthy, cancer affected and edema brain tissues
The brain tumors, are the most common and aggressive disease, leading to a very short life expectancy in their highest grade. Thus, treatment planning is a key stage to improve the quality of life of patients. Generally, various image techniques such as Computed Tomography (CT), Magnetic Resonance …

Modeling the soft tissues of the knee joint
Computational modeling of the knee helps us better understand the forces and strains placed on knee structures, such as the ligaments and cartilage, during ambulatory activities. With better understanding of ligament strains and cartilage pressures during different loading situations, we are able …

Continuum Models of Collective Migration in Living Tissues
… to probe the mechanical properties of cells and tissues. In Chapter 2 we formulate our minimal continuum model of a tissue as an overdamped active elastic medium on a frictional substrate. The model couples mechanical deformations in the tissue to myosin-based contractile activity and to cell …
