Microtubule Dynamics in Neuronal Morphogenesis
… the effect of microtubule dynamics on neuronal morphogenesis.

Computational Morphogenesis of City Tissues
… complex systems through the study of biological morphogenesis (the formation and development of organisms over time) for their implementation in formalising a design model for the formation, development and evolution of cities. The central contribution of the thesis lies in the computational …

Bioartificial matrices to modulate epithelial morphogenesis
… to repair or replace damaged tissues. Epithelial morphogenesis is a hard-wired, multicellular differentiation program that dynamically integrates microenvironmental cues to coordinate cell fate processes including adhesion, migration, proliferation, and polarization. Thus, epithelial morphogenesis …

Biophysical Mechanisms of Early Heart Morphogenesis
<p>The heart is the first functioning organ in the developing embryo. Initially, the heart is a relatively straight tube created by folding and fusion of the cardiogenic fields, which lie bilaterally within the blastoderm. Shortly after formation, the primitive heart tube (HT) undergoes the …

Morphogenesis in the moss physcomitrella patens
A method was developed for recording the development of moss protonema using time-lapse video microscopy. This has provided a detailed record of the time-course of development from spore germination to the production of gametophores. Detailed records of the growth of primary and secondary …

Molecular Regulation of Hair Follicle Morphogenesis
… layer of multipotent cells during embryogenesis. Morphogenesis of hair follicles is initiated when a series of reciprocal interactions between this undifferentiated ectoderm and its underlying mesenchyme leads to a localized invagination of epithelial cells. As hair follicle development proceeds, …

Sensory Organ Morphogenesis in Caenorhabditis Elegans
… cells, which establish a niche important for the morphogenesis and function of the neurons. Although similar glial compartments are seen throughout the nervous system, their morphogenesis is poorly understood. In the work presented here, I use the main sensory organ of Caenorhabditis elegans, the …

Morphogenesis of the Bacillus Anthracis Spore
<p>With the ability to shut down metabolism, survive exposure to high degrees of heat, ultra-violet and ionizing radiation, digestive enzymes, and antimicrobials, the bacterial spore is one of the most-resistant forms of life on earth. Although most spores are harmless, several species' spores …

MECHANOBIOLOGICAL REGULATION OF ATRIOVENTRICULAR VALVE MORPHOGENESIS
… cellular activities that bring about valve morphogenesis. The objective of this thesis was to elucidate the influence of mechanical stress on the biology of valve embryonic cells to determine how mechanical stimuli regulate normal development and act as epigenetic causes of congenital …

Engineering morphogenesis of Marchantia polymorpha gemmae
Morphogenesis is an apparent yet complex process: emergence of a plant shape is the result of an intricate interplay between genetic regulation, cell physiology and mechanical processes at the tissue scale. Morphogenesis spans three levels of biological organisation, forming a nested complex …

Synthetic morphogenesis : space, time, and deformation
Synthetic biology has presented engineers with a fascinating opportunity: can we understand the principles of our origins { animal embryonic development - by re-engineering it in the laboratory? I investigate, from an engineer's perspective, some of problems that arise in developing geometric form …

Modelling morphogenesis as an amorphous computation
… presents a programming-language viewpoint for morphogenesis, the process of shape formation during embryological development. We model morphogenesis as a self-organizing, self-repairing amorphous computation and describe how we can program large-scale shape formation by giving local …

Fate, Phases, and Form in Vertebrate Organ Morphogenesis-Uncovering a Role of Morphogenesis at the Supracellular Scale
<p>How morphology unfolds from fertilization to birth is one of the most fundamental questions in the life sciences. Self-organization in embryonic development, whereby organs robustly adopt forms through intrinsic processes, is a central feature that remains enigmatic. To achieve greater clarity …

Merlin Mediated Regulation of Hair Follicle Morphogenesis
<p>Epidermal homeostasis is paramount for the ongoing function of the skin as the primary barrier between a mammalian organism and the external environment. Homeostasis is achieved through a complex and delicate balance of cell death, cell proliferation and cell differentiation. Critical for …

Morphogenesis and Female Fate Determination in Vertebrates
… in vertebrates, the intricacies of ovarian morphogenesis are not well understood. A key event in ovarian development occurs around birth, when meiotic germ cells and somatic granulosa cells organize into primordial follicles, the structures that generate mature oocytes for ovulation in adult …
