1. 1. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development

   Författare :Lina Dahl; Leif Carlsson; Jan-Ingvar Jönsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

   Sammanfattning : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. LÄS MER

3. 2. Hematopoietic stem and progenitor cells and potentials for application in fetal cell replacement therapy

   Författare :Karina Liuba; Lund Obstetrik och gynekologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in utero hematopoietic cell transplantation; hematopoietic stem cell; multipotent progenitor; fetal therapy; heterotypic cell fusion;

   Sammanfattning : Fetal cell replacement therapy or in utero hematopoietic cell transplantation (IUHCT) is proposed as a non-myeloablative alternative to bone marrow transplantation (BMT) for a number of inborn immunologic, hematologic and metabolic disorders. IUHCT represents the method through which variable amounts of natural or genetically modified hematopoietic cells can be transferred to the fetal recipient in hope of correcting the disorder and preventing postnatal permanent organ damage.

4. 3. Identification of Unique Hematopoietic Stem Cell Properties

   Författare :Jens Nygren; Lunds universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Hematologi; extracellulära vätskor; Haematology; extracellular fluids; cell cycle; fusion; transdifferentiation; plasticity; Medicine human and vertebrates ; Medicin människa och djur ; quiescence; hematopoietic stem cell; self-renewal;

   Sammanfattning : Hematopoietic stem cells (HSC) are sufficient and required for life long production of all blood cell lineages. Steady state HSCs are largely quiescent and we demonstrate that the kinetics of HSC cell cycling are slower compared to more committed progenitor cells also during expansion and self-renewal ex vivo and in physiological conditions.

5. 4. Stem and progenitor cell involvement in acute lymphoblastic leukemia

   Författare :Anders Castor; Stamcellscentrum (SCC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; Haematology; Cytology; oncology; cancerology; Cytologi; onkologi; Medicin människa och djur ; Medicine human and vertebrates ; ETV6-RUNX1; BCR-ABL1; stem cells; Acute lymphoblastic leukemia; extracellular fluids; Hematologi; extracellulära vätskor;

   Sammanfattning : Leukemic stem cells (LSCs) share the capacity of self renewal and extensive proliferation with normal hematopoietic stem cells (HSCs), and are therefore obvious targets for therapy. As such, they need to be identified and characterized in order to elucidate what drives them, and what separates them from their normal counterparts. LÄS MER

7. 5. Label-free processing of stem cell preparations by acoustophoresis

   Författare :Franziska Olm; Avdelningen för molekylär hematologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acoustophoresis; label-free cell separation; ultrasound; microfluidics; stem cell processing; CTC separation;

   Sammanfattning : The first bone marrow transplant in a human was performed in 1959, providing evidence that cells can be used for transplantation and treatment, revealing that healing capacities lie within the human body that ought to be understood. Since then hematopoietic stem cell transplantation has developed as a standard treatment for many cancers besides other malignancies. LÄS MER
