    Sammanfattning : 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. LÄS MER

    Sammanfattning : B cells are essential cells that are part of the adaptive immune system with the capacity to produce antibodies against exogenous antigens. These cells are produced through a process called hematopoiesis, tightly regulated by extrinsic and intrinsic factors. LÄS MER

  4. 3. Human spinal cord transplantation : experimental and clinical application

    Sammanfattning : The main objectives of this Thesis was to further characterize the in situ human first trimester spinal cord tissue and to evaluate the survival, integration and possible neurological effects of solid human embryonic spinal cord grafts transplanted to cavities in the spinal cord of rat and man. Human-specific neurofilament and Thy-1 positive fibers were observed already at 5 weeks of gestation in the in situ human spinal cord, the earliest stage at which donor tissue was used for intraspinal transplantation.
