[From tumor tissue via primary cultures to xenograft models: a functional approach in prostate cancer research]. J Cell Biol. We show here that culture on a reconstituted basement membrane from Engelbreth-Holm-Swarm tumor (EHS) allows greater than 90% of cells to produce high levels of beta-casein. A three-dimensional cell system composed of immortalized oral keratinocytes (iMOK) cultured on reconstituted basement membrane (ECM) was used to investigate the development of epithelial layers upon exposure to TEGDMA. The effects of reconstituted basement membrane (Matrigel) on in vivo survival and growth of several murine tumors were studied. For long-term use, organoids are commonly embedded within an Engelbreth-Holm Swarm (EHS) matrix derived from the reconstituted basement membrane of mouse sarcoma. Prostatic epithelial cells undergo rapid proliferation and lose their ability to synthesize and secrete prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) under standard tissue culture conditions. Thus, the present invention 3 relates to: a process for producing a reconstituted artificial tissue wherein certain cells having an ability to form a basement membrane are seeded and cultured on a basement membrane specimen or amorphously basement membrane components-deposited specimen (paragraph 30); the process for producing a reconstituted … PY - 1992/4.
