摘要： Subjecting a heterogeneous cell population (one with both stem cells and non-stem cells) to extreme stress selectively eliminated the non-stem cells and resulted in the enrichment of stem cells in the population. The stress can take many forms, including without limitation, cell toxins, high temperature, high salt, and low oxygen (hypoxic) conditions. The number of stem cells remaining after stress were increased, and showed increased expression of traditional stem cell markers. The stem cells were shown to be capable of proliferation and differentiation into multiple types of cells. This method allows purification of stem cells from adult heterogeneous cell populations on a large scale basis without requirement of expensive equipment, and without requiring the presence of cell surface markers. Stem cells produced by the above method can be used for clinical applications, including tissue engineering.

摘要： According to some embodiments of the invention, a near-infrared fluorescence endoscopic dental imaging system includes an endoscope forming a plurality of lumens therein; a spectrometer optically coupled to a first lumen of the endoscope; a near-infrared camera optically coupled to a second lumen of the endoscope; a data processor in communication with the spectrometer and the near-infrared camera; and a display system in communication with the data processor. The near-infrared camera is configured to capture a near-infrared two-dimensional dental image of a specimen and transmit the near-infrared two-dimensional dental image to the data processor. The spectrometer is configured to capture fluorescent light from the specimen and provide a spectroscopic signal to the data processor. The display system is configured to communicate with the data processor to receive the near-infrared two-dimensional dental image and the spectroscopic signal and to display a two-dimensional dental image of the specimen.

摘要： A mouthwash for fluorescence endoscopic dental imaging includes at least one fluorescent dye and a liquid base. A method for fluorescent endoscopic dental imaging includes orally administering a mouthwash to a subject; waiting a predetermined period of time; removing excess mouthwash from the subject; illuminating the subject with visible or near-infrared light; and capturing fluorescent light from the subject to create an image.
