  2. 1. Heart Regeneration : Lessons from the Red Spotted Newt

    Author : Nevin Witman; Jamie Morrison; Thomas Braun; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Heart; Regeneration; Newt; microRNAs; RNA editing; molekylärbiologi; Molecular Biology;

    Abstract : Unlike mammals, adult salamanders possess an intrinsic ability to regenerate complex organs and tissue types, making them an exciting and useful model to study tissue regeneration. The aims of this thesis are two fold, (1) to develop and characterize a reproducible cardiac regeneration model system in the newt, and (2) to decipher the cellular and molecular underpinnings involved in regeneration.

  4. 2. Liver regeneration : With reference to malnutrition and growth factors

    Author : Stefan Skullman; Linköpings universitet; []
    Keywords : cholecystokinin; energy substrates; epidermal growth factor; insulin-like growth factor I; liver composition; liver regeneration; malnutrition; pancreaticobiliary diversion; protein synthesis; rat; transfonning growth factor alpha; MEDICINE; MEDICIN;

    Abstract : The liver has a unique capacity to regenerate after damage, irrespective of cause. The regulatory mechanisms of this regeneration are not fully known. Liver regeneration· is associated with rapid growth and thereby increased demands for energy and synthesis of new compounds. READ MORE

  5. 3. Vitamin A regulated neuronal regeneration and homeostasis

    Author : Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

    Abstract : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. READ MORE

  6. 4. Galactosaminoglycans - Role in Brittlestar Limb Regeneration

    Author : Rashmi Ramachandra; Dorothe Spillmann; Barbara Mulloy; Uppsala universitet; []
    Keywords : Chondroitin sulfate; Dermatan sulfate; Brittlestar; Regeneration;

    Abstract : Regeneration is, in simple terms, ‘to re-grow’ damaged or lost parts of the body (e.g. cells, tissues and organs) and is a natural phenomenon occurring throughout the life of an organism. The regenerative capacity varies in the animal kingdom. READ MORE

  7. 5. Hair cell regeneration in vestibular epithelia : a study in an in vitro model

    Author : Mimmi Werner; Diana Berggren; Andrew Forge; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vestibular hair cell; regeneration; transdifferentiation; proliferation; utricle; rat; oto-rhino-laryngologi; Oto-Rhino-Laryngology;

    Abstract : BackgroundHair cells (HCs) are the sensory receptors in both the auditory and the vestibular organs of the inner ear. Supporting cells (SCs) are non-sensory cells embracing the HCs. Injuries of the HCs by aging, acoustic trauma or ototoxic drugs (mainly aminoglycosides, e.g. READ MORE
