Abstract: The present invention relates generally to a method for detecting an aberrant cell in a subject or in a biological sample from said subject and agents useful for same. The presence of the aberrant cell or group of aberrant cells provides an indication of a particular disease or condition or a propensity for development of a disease or condition. More particularly, the present invention contemplates a method for detecting a cell associated with cancer or having a propensity to develop into a cancer cell in a subject or in a biological sample from said subject by determining the relative increase in the presence of a LIM kinase protein or a related enzyme or a relative increase in LIM kinase activity or a relative increase in the presence of expression products from a gene encoding a LIM kinase or a related protein.

Abstract: A method for the in vitro production of lines of immortalized neural precursor cells, including cell lines having neuronal and/or glial cell characteristics, comprises the step of infecting neuroepithelium or neural crest cells with a retroviral vector carrying a member of the myc family of oncogenes.
