    Sammanfattning : The aim of this thesis is to model and describe dynamical events for biologicalcells using statistical and mathematical tools. The thesis includes five papersthat all relate to stochastic modelling of cells. LÄS MER

  2. 2. Glycosaminoglycan Biosynthesis and Function in Zebrafish Development Sugars Shaping Skeletons

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Judith Habicher; Uppsala universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Heparan sulfate (HS) and chondroitin/dermatan sulfate (CS/DS) proteoglycans are glycosylated proteins with important roles in animal development and homeostasis. HS and CS/DS are long, linear glycosaminoglycan (GAG) polysaccharides and attached to a core protein they form proteoglycans. LÄS MER

  3. 3. A Comparative Study of Head Development in Mexican Axolotl and Australian Lungfish: Cell Migration, Cell Fate and Morphogenesis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Rolf Ericsson; Uppsala universitet.; [2003]

    Sammanfattning : The development of the vertebrate head is a complex process involving interactions between a multitude of cell types and tissues. This thesis describes the development of the cranial neural crest and of the visceral arch muscles in the head of two species. LÄS MER

  4. 4. Epigenetic Regulation of the H19 Chromatin Insulator in Development and Disease

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : The coordinated regulation of gene expression must be tightly controlled for normal development to occur. In mammals, this issue is further complicated by the requirement of both the maternal and paternal genomes for normal development, reflecting the fact that a subset of genes are monoallelically expressed depending on parental inheritance, a phenomenon known as genomic imprinting.

  5. 5. Epigenetic Control of Mammalian Development : Studies on an imprinting control region

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Liang Liu; Uppsala universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Epigenetic; Genomic imprinting; DNA methylation; Igf2; H19; Insulator; CTCF; Imprinting control region; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; zoologisk utvecklingsbiologi; Animal Development;

    Sammanfattning : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. LÄS MER
