1. 11. Regulatory Proteins in Progenitors and Differentiated Cells of the Human Prostate

   Författare :Jens Ceder; Malmö (Abrahamsson) Urologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mesenchymal stem cells; somatostatin; transit amplifying cells; cell differentiation; adult stem cells; Prostate gland; prostatic benign hyperplasia; neuroendocrine cells; prostate cancer;

   Sammanfattning : Prostate cancer (PC) develops from an androgen-dependent tissue that contains androgen receptors in both the stromal and glandular compartments. Surgical removal of the prostate may cure the patient, but if metastatic spread has occurred, androgen suppression therapy is the standard treatment. LÄS MER

3. 12. Auxiliary Cells for the Vascularization and Function of Endogenous and Transplanted Islets of Langerhans

   Författare :Liza Grapensparr; Per-Ola Carlsson; Leif Jansson; Mia Phillipson; Aileen King; Uppsala universitet; []
   Nyckelord :Islets of Langerhans; beta cells; diabetes; transplantation; vascularization; Schwann cells; endothelial progenitor cells; neural crest stem cells; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Type 1 diabetes develops through the progressive destruction of the insulin-producing beta-cells. Regeneration or replacement of beta-cells is therefore needed to restore normal glucose homeostasis. Presently, normoglycemia can be achieved by the transplantation of whole pancreas or isolated islets of Langerhans. LÄS MER

4. 13. Dental mesenchymal stem cells

   Författare :Nina Kaukua; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Mesenchymal stem cells have been found in various tissues and act as source for renewal and repair. The mouse incisor tooth continuously grows throughout life, implicating that there are stem cell niches constantly contributing with cells. The composition of these stem cell niches is not fully understood. LÄS MER

5. 14. Mechanisms of survival and maintenance of Hematopoietic Stem Cells and Multipotent Progenitor Cells

   Författare :Richard Karlsson; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; Hematologi; extracellular fluids; Haematology; hypoxia.; forkhead; Akt PKB; Bcl-2; apoptosis; Flt3; FL; c-kit; KL; cytokines; Hematopoiesis; progenitor;

   Sammanfattning : Hematopoietic stem cells and progenitor cells are maintained in the bone marrow microenvironment, where factors including soluble and membrane-bound cytokines influence the processes of self-renewal, proliferation and differentiation. Two nonreduntant cytokines with effects on hematopoiesis, Kit Ligand (KL) and Flt3 Ligand (FL), signal via related tyrosine kinase receptors, c-kit and Flt3. LÄS MER

7. 15. NEURAL STEM/PROGENITOR CELLS IN THE POST-ISCHEMIC ENVIRONMENT: Proliferation, Differentiation and Neuroprotection

   Författare :Jonas Faijerson; Göteborgs universitet; []
   Nyckelord :neural stem cells; neural progenitor cells; stroke; ischemia; reactive astrocytes; astrogliosis; proliferation; differentiation; neurogenesis; excitotoxicity; transfection; neuroprotection;

   Sammanfattning : Stroke is one of the leading causes of chronic disability and death in the Western world. Today, no treatment can repair the cellular loss associated with an ischemic lesion. LÄS MER
