  1. 1. Retinal Transplants: Growth Differentiation Integration Organization and Survival

    Författare :Rajesh Kumar Sharma; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal degeneration; Retinal transplants; retinal development; treatment; connections; proliferation; survival; Ophtalmology; Oftalmologi;

    Sammanfattning : The goal of the study was to get a better understanding of factors controlling the growth, differen-tia-tion, integration, organization and survival of retinal transplants, with the long-term view of eventually developing retinal transplantation into a clinically useful procedure for treating degenerative retinal disorders such as retinitis pigmentosa. Embryonic day 15 rabbit retinas were transplanted into adult rabbit eyes and were allowed to survive for various times. LÄS MER

  3. 2. Experimental porcine models of retinal ischemia

    Författare :Håkan Morén; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal ischemia; animal model; multifocal electroretinography; intraarterial coiling; retinal vasculature;

    Sammanfattning : Retinal ischaemia resulting from e.g. diabetes, vein thrombosis or arterial occlusion, is one of the major causes of visual impairment and blindness. Although new methods of treatment are being developed, there is still a need for more effective pharmacological forms of treatment. LÄS MER

  4. 3. Modulation of retinal progenitors : A bird’s-eye view of retinal regeneration and disease

    Författare :Dardan Konjusha; Finn Hallböök; Rusty Lansford; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Developmental neurobiology; Retinoblastoma; MYCN; Cone photoreceptor; Nolz1; Endothelin; Müller cells;

    Sammanfattning : The cell populations of the retina and their intricate organization provide us with one of the most important senses – vision. All retinal cell populations are derived from a common progenitor pool as a result of tight regulation of proliferation, differentiation, dedifferentiation, and programmed cell death. LÄS MER

  5. 4. Characterization of Retinal Progenitor Cells : Focus on Proliferation and the GABAA Receptor System

    Författare :Henrik Ring; Finn Hallböök; Per Söderberg; Andras Simon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regeneration; Proliferation; Neurotransmitters; Müller cells; Differentiation; Retinal repair; Neurogenesis; Medical Science; Medicinsk vetenskap;

    Sammanfattning : One strategy to repair an injured or degenerated retina is to stimulate the replacement of damaged or dead neurons with cells derived from endogenous stem- or progenitor cells. A successful strategy requires knowledge about how the proliferation and differentiation of the endogenous cells are regulated. LÄS MER
