Abstract: The invention relates to a therapeutic composition, a method for producing a therapeutic composition, and the use of a cell-free substance, especially a cell-free bone or cartilage matrix. The disclosed therapeutic composition comprises at least a cell-free substance obtained from stimulated stem cells and/or precursor cells. Immunogenic reactions during in vivo therapeutic use are prevented by the fact that the therapeutic composition is free from cells and contains no typically antigenic cell components. The disclosed composition can therefore be universally used for the therapeutic purposes regardless of the origin of the stem cells and/or precursor cells and utilize the natural regenerative potency thereof in a highly efficient manner for replacing tissue, e.g. for a suitable bone and/or cartilage structure.

Abstract: Subject of the invention is a method for generating neural stem cells in vitro, wherein dental progenitor cells are isolated from soft tissue of tooth or wisdom tooth and cultivated until they form primary spheres which are then dissociated into single cells. These single cells are cultivated until they form spheroids and the spheroid-forming cells are separated to obtain neural stem cells.

Abstract: The invention relates to a method for isolation of multipotent stem cells from dental tissue in which the stem cells are extracted from a tissue structure and then cultured. The invention also relates to stem cells isolated by means of the method according to the invention as well as bone cells and nerve cells produced by means of the method according to the invention. The invention also relates to a method for producing a bank of stem cells in which the cells are stored by means of the method according to the invention. According to the present invention, the cells of a pad-like soft tissue that can be localized beneath the papilla directly on the apical side of an extracted immature tooth are cryopreserved in the tissue structure such that the tissue structure is disintegrated to extract the stem cells only after thawing.

Abstract: A process for qualitative and quantitative analysis of an analyte in a solution includes irradiating a first chromophore with an electro-magnetic radiation while simultaneously moving an arrangement structure and the analyte relative to one another in a manner which effects extension of the elastic coupling interconnecting the first chromophore and a second chromophore. The process also includes measuring the intensities of a fluorescent light having a respective wavelength ?1 and a fluorescent light having a respective wavelength ?2 during the movement of the arrangement structure and the analyte relative to one another. The type and the amount of the analyte is determined as a function of the intensities of the fluorescent light having the respective wavelength ?1 and the fluorescent light having the respective wavelength ?2.

Abstract: A sensor device having a magnetostrictive force sensor is provided. To detect a force, the sensor device contains a TMR force sensor element having a magnetic detection layer of material having a magnetostriction coefficient ??|5·10?6|, a magnetically harder reference layer, and a tunnel barrier disposed between these layers. Established in the detection layer is a starting magnetization that relative to the magnetization of the reference layer, which is directed in the direction of force, forms an angle of other than 0° and thus is rotated out of its starting position under the effect of the force.
