Abstract: A method for preparing a tissue culture insert that is used for constructing a transplantable graft of an engineered tissue equivalent comprising living main functional cells, stromal cells and tissue matrix on/in a biological supporting membrane for treatment of body tissue defects.

Abstract: The present invention relates to the identification and characterization of classes and subclasses of circulating cancer cells, including microtumors from body fluid samples using molecular, cytological, and morphological analyses, and methods for staging patients and measuring the efficacy of medical treatments.

Abstract: The invention described herein encompasses novel discovery of anticancer agents and its compositions comprising saponins, a group of triterpenoid and steroidal saponins found in plants including Quillaja saponaria Molina (soap tree), which are used as therapeutic compounds for the treatment and prevention of cancer diseases or as a dietary supplement that offers tumor cell killing and tumor cell inhibition, and also as a anticancer potentiator with other anticancer agents.

Abstract: The present invention provides for enriching rare cells in a fluid comprising the rare cells and non-rare cells. Examples of rare cells enriched include prostate cancer cells.

Abstract: A method for enriching cancer cells such as prostate cancer cells in a bodily fluid sample is disclosed comprising (a) obtaining the sample comprising cancer cells and non-rare cells; (b) subjecting the sample to multiple density gradient separation comprising a first density gradient and a second density gradient, wherein the second density gradient is greater than the first density gradient, and producing a first fluid comprising an increased concentration of cancer cells of a first density, and a second fluid comprising an increased concentration of cancer cells of a second density, wherein the second density is greater than the first density; wherein subjecting the sample to multiple density gradient separation includes producing a plasma layer, a first interface layer, a first gradient layer, a second interface layer, a second gradient layer, and a cell pellet; wherein producing the first fluid includes combining the first interface layer and the first gradient layer and forming a first suspension; and w
