  1. 1. Immunological aspects of maternal-foetal interactions in mice

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Marie Arvola; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Neonatal mice; milk; placenta; fetal rejection; IgG; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : Mammalian pregnancy is an immunological paradox. The foetus, which expresses both paternal and maternal cell-surface molecules, has to be protected from rejection by the maternal immune system. At the same time, the mother has to have an efficient immune defence and must provide her offspring with antibodies. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Rolf Ericsson; Rolf Ohlsson; Graham Budd; Lennart Olsson; Per Ahlberg; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Head development; axolotl; lungfish; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Claes Holmgren; Rolf Ohlsson; Tomas Ekstöm; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Developmental Biology; Miljömedicinsk utvecklingsbiologi;

    Abstract : 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.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Liang Liu; Pärt Peterson; [2002]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Gene expression and its physiological control in disease and development Studies on the human PDGF-B gene and tumour hypoxia

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Ullerås; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Zoologisk utvecklingsbiologi; Animal Development;

    Abstract : Strict control of gene expression is essential during development and in response to physiological stimuli. This thesis describes the functional characterisation of the gene regulatory mechanisms controlling the expression of the potent human growth factor Platelet Derived Growth Factor B gene, in a cell type specific context and in response to low oxygen tension.
