1. Development and three-dimensional histology of vertebrate dermal fin spines
Sammanfattning : Jawed vertebrates (gnathostomes) consist of two clades with living representatives, the chondricthyans (cartilaginous fish including sharks, rays, and chimaeras) and the osteichthyans (bony fish and tetrapods), and two fossil groups, the "placoderms" and "acanthodians". These extinct forms were thought to be monophyletic, but are now considered to be paraphyletic partly due to the discovery of early chondrichthyans and osteichthyans with characters that had been previously used to define them.

2. Development of the Mouse Lateral Telencephalon
Sammanfattning : The telencephalon is the most rostral part of the vertebrate central nervous system and is comprised of a number of structures important for voluntary movements and higher cognitive processes. This thesis focuses on the genetic mechanisms that control development of a number of telencephalic structures: the olfactory bulb, the striatum as well as the lateral and basolateral nuclei of the amygdala.

3. Musculoskeletal Development in Jawed Vertebrates : Gene function, cis-regulation, and 3D phenotypes in zebrafish
Sammanfattning : Vertebrate skeletons are an intricate framework of bony and cartilaginous structures that form through carefully orchestrated developmental processes, guided by interacting genetic pathways that regulate cellular differentiation, migration, and tissue morphogenesis. The specific timing and localisation of gene expression shapes the diverse array of skeletal elements, from the flexible cartilages of the embryonic stage to the hardened bones that provide structural support in adulthood, and the joints and connective tissues that articulate the musculoskeletal system.

4. Development of photoreceptor organs in teleosts, Molecular and immunocytochemical studies
Sammanfattning : Many vertebrate animals are known to have multiple sites for photoreception that are not involved in vision. Extraretinal photoreception is indicated to play a crucial role in early development, physiology and behavior, as well as in later biological processes. LÄS MER
5. Neuronal Development in the Embryonic Retina : Focus on the Characterization, Generation and Development of Horizontal Cell Subtypes
Sammanfattning : Horizontal cells are retinal interneurons that modulate the output from photoreceptors. Two horizontal cell (HC) subtypes are commonly identified in the vertebrate retina: axon-bearing and axon-less HCs. LÄS MER
