1. A Comparative Study of Head Development in Mexican Axolotl and Australian Lungfish: Cell Migration, Cell Fate and Morphogenesis
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
2. Epigenetic Regulation of the H19 Chromatin Insulator in Development and Disease
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. LÄS MER
3. Immunological aspects of maternal-foetal interactions in mice
Sammanfattning : 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. LÄS MER
4. Chromatin regulators and transcriptional control of Drosophila development
Sammanfattning : The development of a multicellular organism is programmed by complex patterns of gene expression. In eukaryotic cells, genes are packaged by histone proteins into chromatin. Chromatin regulators often function as transcription co-factors. LÄS MER
5. Functions of Transcriptional Co-regulators in Drosophila development
Sammanfattning : During Drosophila development, regulation of gene expression through interplay between transcriptional activators and repressors is generating complex patterns of gene expression that leads to cell differentiation. For proper control of transcription, transcription factors bind to DNA at control regions, so called Cis Regulatory Modules (CRM). LÄS MER
