Disclosed herein are non-myeloablative antibody-toxin conjugates and compositions that target cell surface markers, such as the CD34, CD45 or CD117 receptors, and related methods of their use to effectively conditioning a subject's tissues (e.g., bone marrow tissue) prior to engraftment or transplant. The compositions and methods disclosed herein may be used to condition a subject's tissues in advance of, for example, hematopoietic stem cell transplant and advantageously such compositions and methods do not cause the toxicities that are commonly associated with traditional conditioning methods.

The present invention relates to a new cell based assay for determining antibody or ligand binding and function using lipid-like compounds capable of spontaneous integration into cell membranes

The present invention relates to compositions comprising magnetic particles, the methods of using these compositions in processing animal sperm, the resulting sperm and embryo products, and the methods of use of these compositions to increase the efficiency, efficacy and/or speed of cell processing and artificial insemination techniques.

The present invention relates to the use of the biomarker Flattop (Fltp) for distinguishing mature cells from immature progenitor cells. The present invention further relates to a method for distinguishing a mature cell from an immature progenitor cell, the method comprising: determining the presence or absence of the biomarker Flattop (Fltp) in a cell; wherein the presence of Fltp in the cell indicates that the cell is a mature cell and wherein the absence of Fltp in the cell indicates that the cell is an immature progenitor cell. Furthermore, the present invention relates to a method of identifying a compound suitable for differentiating immature progenitor cells into mature cells as well as to a method of identifying a compound suitable for preventing the de-differentiating of mature cells. The present invention additionally relates to a method of differentiating immature progenitor cells into mature cells as well as to a method of preventing de-differentiating of mature cells. In addition, the present invention also relates to a kit for distinguishing mature cells from immature progenitor cells and to a pharmaceutical composition for use in treating or preventing diabetes.

The present invention relates to a method for the isolation of subpopulations of cardiac progenitor cells from a heart tissue sample, the population thus obtained and the related uses in the medical field for the cell therapy or cardiac cell and/or tissue transplantation field.

[Problem] To provide a cell preparation including mesenchymal stem cells (MSCs) having a high therapeutic effect. [Solution] A method for producing activated mesenchymal stem cells, including a step of culturing MSCs in a medium containing an activator that includes an extract from a mammalian fetal appendage as an active ingredient, using a cell culture carrier having a three-dimensional structure formed of a fiber is provided. A marker for a therapeutic effect of MSCs selected from the group consisting of p16ink4a, p14ARF, CDK4, CDK6, RB, and CD47, a method for determining a therapeutic effect using the maker, a method for determining suitability of MSCs to be treated with a treatment for enhancing a therapeutic effect of MSCs, a cell preparation including MSCs, and a method for producing the same are also provided.

A system for isolating preselected cell types from a fluid sample that includes a plurality of cell types includes a cell-capture fluidic chip, and a chip holder configured to receive the cell-capture fluidic chip and to maintain the cell-capture fluidic chip with a substantially fluid-tight seal while in operation. The chip holder is further configured to release the cell-capture fluidic chip to be removed from the chip holder for further processing. The cell-capture fluidic chip includes a substrate, a laser micro-dissection membrane disposed on the substrate, and a channel-defining layer disposed on the laser micro-dissection membrane. The laser micro-dissection membrane has a surface adapted to capture preselected cell types preferentially over other cell types of the plurality of cell types. The channel-defining layer is removable from the laser micro-dissection membrane for further processing of the cell-capture fluidic chip.

Fibronectin type III domains (FN3) that specifically bind to CD8A, related polynucleotides capable of encoding CD8A-specific FN3 domains, cells expressing the FN3 domains, as well as associated vectors, and detectably labeled FN3 domains are useful in therapeutic and diagnostic applications.

The present invention relates to a two-part device, wherein a first part is an engineered antigen-presenting cell system (eAPCS), and a second part is an engineered TCR-presenting cell system (eTPCS).

Platform technology involving aqueous microdroplet reaction vessels created, arrayed, and characterized by imaging microscopy in a microfluidic device are applied to a wide variety of bioassays involving the detection and phenotypic characterization of single cells. The bioassays include the rapid and automated detection of microbial pathogens and their antibiotic sensitivity from patient samples as well as the characterization of immune responses using a patient's own cells, including the killing of tumor cells.
