  1. 1. Studies of transforming growth factor alpha in normal and abnormal growth

    Författare :Anna-Lotta Hallbeck; Åke Wasteson; Thomas Walz; Annelie Lindström; Carl-Henric Heldin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-alpha; HER; EGFR; synovia; synovial sarcoma; RA; synovitis; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : Regulation of growth is of fundamental importance for development of the organism and to maintain health. The induction of cell proliferation and matrix production are influenced by several different signaling systems, most importantly by growth factors. LÄS MER

  3. 2. Pancreatic Growth and Secretion. An Experimental Study on Growth Factors in Rat and Mouse

    Författare :Claes Hjalmarsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; PBD; insulin; B-cells; bile; pancreatic cancer; intestine; secretion; pancreas; proliferation; tyrphostins; CCK; epidermal growth factor; transforming growth factor alpha; cancerology; Cytologi; onkologi; cancer; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : The pancreas is a central organ in the digestion of food as well as in glucose metabolism. Its two major functions are exocrine and endocrine secretion. LÄS MER

  4. 3. Growth factors in spermatogenesis

    Författare :Aida Wahlgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Testis; seminiferous tubules; proliferation; growth factors; sex steroids;

    Sammanfattning : The aim of this study was to increase the knowledge of die effects of locally produced growth factors and hormones on germ cell proliferation in rat testis in vitro. Since impaired sperm production and function accounts for half the cases of infertility, it is important to understand the physiological actions in germ cell development. LÄS MER

  5. 4. Growth regulation in sarcomas : studies in vivo and in cell culture

    Författare :Avni Abdiu; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Sarcomas are malignant tumors of mesenchymal origin, and can arise in soft-tissue and in bones. It has been suggested that the abnormal growth regulation in sarcoma cells may be due to an autocrine mechanism, in which the cells are stimulated by an endogenous production of growth factors.

  7. 5. Paracrine regulation of Sertoli cell proliferation

    Författare :Cecilia Petersen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Testis; Sertoli cell; proliferation; growth factor; proinflammatory cytokine;

    Sammanfattning : The Sertoli cell is a highly differentiated somatic cell in the seminiferous epithelium of the testis. This cell is of prime importance for both testicular development and spermatogenesis. LÄS MER
