2. 1. Identification and characterization of progenitor populations in the human adult heart

   Author : Joakim Sandstedt; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cardiac progenitor cells; heart; C-kit; Side Population; Stage Specific Embryonic Antigens; FACS;

   Abstract : Traditionally, the heart has been regarded as a non-regenerative organ. During the last 10 years, this notion has been challenged. By 14C measurements, it was calculated that at the age of 50, about 45% of all cardiomyocytes had formed after birth. READ MORE

4. 2. Common mechanism for teratogenicity of antiepileptic drugs : Drug-induced embryonic arrhythmia and hypoxia-reoxygenation damage

   Author : Faranak Azarbayjani; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Atiepileptik drugs; embryonic heart; arrhythmia; cleft palate; ROS; antioxidants; Ikr; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

   Abstract : The Antiepilptic drugs (AEDs) phenytoin (PHT), carbamazepine (CBZ), phenobarbital (PB), tri- and dimethadione (TMD and DMD) are known teratogens having a common malformation pattern in human and animal studies. This thesis was designed chiefly to test a hypothesis correlating the teratogenicity of these AEDs to episodes of pharmacologically induced embryonic arrhythmia and hypoxia-reoxygenation damage.

5. 3. Transcriptional profiling of human embryonic stem cells and their functional derivatives

   Author : Jane Synnergren; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcription; differentiation; human embryonic stem cells; gene expression; Naturvetenskap;

   Abstract : Human embryonic stem cells (hESCs) represent populations of pluripotent, undifferentiated cells with unlimited replication capacity, and with the ability to differentiate into any functional cell type in the human body. Based on these properties, hESCs and their derivatives provide unique model systems for basic research on embryonic development. READ MORE

6. 4. Gene Expression in mESC Deficient in FGFR Signalling and the Identification of the Novel Gene Ened

   Author : Renata Gustafsson; Muskelbiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; embryonic stem cells; differentiation; FGF FGFR signalling; gene expression; microarray; Ened; early embryonic development;

   Abstract : Embryonic stem cells (ESCs) are derived from the inner cell mass (ICM) of blastocyst stage embryos, and upon differentiation into embryoid bodies (EBs) they recapitulate the genetic, cellular and morphological events occurring in early embryogenesis. Among several signalling pathways and inductive factors, the fibroblast growth factors (FGFs) and their receptors (FGFRs) have been shown to be important during early embryogenesis. READ MORE

7. 5. Cell transplantation with human mesenchymal or embryonic stem cells to the heart : experimental, molecular, immunological and echocardiographic studies

   Author : Karl-Henrik Grinnemo; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Human mesenchymal stem cells; human embryonic stem cells; human cardiomyocyte; Islet-1; Nkx2.5; stem cell; xenotransplantation; rejection; FoxP3 T-cells; tolerance; CTLA4Ig; anti- CD40L; LFA-1;

   Abstract : Background: Human mesenchymal stem cells (hMSC), human embryonic stem cells (HESC) and human fetal cardiomyocyte progenitor cells (HFCP) all represent possible candidate cells for regeneration of damaged myocardium. Although they represent cell types with many positive attributes, their capacity to engraft, to differentiate into mature cardiomyocytes, to improve myocardial function and their immunological properties are the focus of these studies.
