    摘要: In dem Verfahren wird eine Malignomgewebeprobe ex vivo gereinigt, zerkleinert, in Kulturmedium suspendiert, einer Behandlung mit Kollagenase unterworfen und das Kollagenaseaufschlußprodukt wird zentrifugiert. Das gewonnene Pellet wird in Kulturmedium mittels eines Aufsauginstruments resuspendiert, dabei mehrmals aufgesogen und wieder zurückgegeben, und in ein Kulturgefäß überführt. Die so gewonnene Resuspension wird mikroskopisch mit Phasenoptik hinsichtlich Zellverbänden analysiert, die aufgrund ihres phänotypischen Erscheinungsbildes als Verband maligner Zellen oder als Verband von Endothelzellen oder als Verband von Fibroblasten identifizierbar sind, und die indentifizierten Zellverbände werden separiert.

    摘要: The present invention relates to methods and compositions for treating a subject comprising destroying diseased cells in the subject. The methods comprise obtaining a population of cells from a subject and determining the activity of at least one disease marker gene within the population of the obtained cells. A polynucleotide molecule that encodes a polypeptide that is lethal to the cells is then introduced into the cells, where the expression of the lethal polypeptide is controlled by the promoter of at least one of the disease marker genes previously identified. After introduction of the polynucleotide, the cells are treated with conditions to induce expression of the lethal polypeptide to destroy the cells that are expressing the disease marker gene(s). After destruction of the diseased cells, the remaining live cells, which did not express the lethal polypeptide to an extent necessary to kill the cells, are separated from the dead cells, and the live cells are restored to the subject.

    摘要: The invention relates to a natural killer cell line termed NK-92. The invention provides a vector for transfecting a mammalian cell which includes a nucleic acid sequence encoding a cytokine that promotes the growth of NK-92. Additionally, the invention provides an NK-92 cell, or an NK-92 cell modified by transfection with a vector conferring advantageous properties, which is unable to proliferate and which preserves effective cytotoxic activity. The invention further provides a modified NK-92 cell that is transfected with a vector encoding a cytokine that promotes the growth of NK-92 cells. The cell secretes the cytokine upon being cultured under conditions that promote cytokine secretion, and furthermore secretes the cytokine in vivo upon being introduced into a mammal. In a significant embodiment, the cytokine is interleukin 2. The present invention also provides methods of purging cancer cells from a biological sample, of treating a cancer ex vivo in a mammal, and of treating a cancer in vivo in a mammal employing a natural killer cell, such as NK-92 itself, an NK-92 cell which is unable to proliferate and which preserves effective cytotoxic activity, or natural killer cells transfected with a vector encoding a cytokine.
