  1. 1. 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.

    Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER

  4. 3. Profilin in cell motility and signal transduction studies using site-specific mutagenesis

    Författare :Camilla Björkegren Sjögren; Tommy Andersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; Zoological Cell Biology; zoologisk cellbiologi;

    Sammanfattning : When a cell is stimulated by signalling molecules such as growth factors, one immediate response is an increased motile activity of the cell. Membrane lamella and spikes appear at the cell surface and perform undulating movements. LÄS MER

  5. 4. Studies on various culture systems for chondrocytes and osteoblasts

    Författare :Juha Prittinen; Mikko Lammi; Minna Kellomäki; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; chondrocyte; osteoarthritis; surface materials; topography; tissue engineering; mechanical stimulation; Medical Cell Biology; medicinsk cellbiologi;

    Sammanfattning : Osteoarthritis and osteochondral defects are ailments that are increasing in frequency as the lifespan of the population increases and sedentary lifestyle becomes more common. Osteoarthritis is an inflammatory disease that causes the progressive degeneration of articular surfaces and the underlying bone. LÄS MER

  7. 5. Generation of midbrain dopaminergic neurons in vivo and in vitro: the role of Neurogenin2

    Författare :Elin Andersson; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Medicin människa och djur ; cell replacement; Parkinson?s; dopamine; neuronal specification; development; mesencephalon; TH; neuronal differentiation; proneural genes; transcription factors; bHLH; neurospheres; stem cell; progenitor cell;

    Sammanfattning : Parkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. LÄS MER
