  4. 2. Cellular models of human brain disorders from skin to brain

    Author : Mansoureh Shahsavani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Studying human brain development and disorders is very challenging. In the absence of comparable model organisms, human-related models, and limitations to obtain live cells from the human brain, induced Pluripotent Stem Cell (iPSC) technology, in particular, provided a unique tool to study the disease mechanisms and investigate potential treatments.

  5. 3. Identification of dopamine neuron progenitors in the embryonic midbrain and stem cell cultures - Studies on the role of neuronal subtype and differentiation state for cell replacemen in a rodent model of Parkinson's disease

    Author : Marie Jönsson; Neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GFP; cell sorting; FACS; Transplantation; ventral mesencephalon; embryonic stem cells;

    Abstract : Parkinson’s Disease (PD) is a neurodegenerative disorder where the dopamine producing neurons in the ventral mesencephalon (VM) progressively die and result in symptoms such as resting tremors, muscle rigidity, slowness and difficulties in initiating movements.Currently there is no cure for PD and the available drug treatments only offer symptomatic relief and are often associated with severe side effects.
