Disclosed herein is a biomimetic coating for use in a microfluidic channel to capture rare cells from a sample while maintaining the viability of the captured cells.

Systems, devices, and techniques are described for characterizing subjects, such as dogs or humans, into risk categories using a blood test. For example, a method includes marking a plurality of cells from a blood sample of a subject with antibodies that recognize a plurality of markers comprising at least two of αvβ.sub.3-integrin, hematopoietic progenitor marker CD34, hematopoietic progenitor marker CD117, hyaluronic acid receptor CD44, or panleukocyte marker CD45 and obtaining, based on expression of the plurality of markers in the plurality of cells, a plurality of data features for the plurality of cells. The method may also include applying a plurality of trained analytical models to a subset of the plurality of data features and generating, based on the trained analytical models, one classification for the blood sample, wherein the classification is selected from at least a high risk of HSA and a low risk of HSA.

Disclosed is a method for detecting regulatory dendritic cells, the method comprising step a: detecting the presence or absence of one or more types of molecules on a cell surface in a cell population that comprises regulatory dendritic cells; and step b: identifying regulatory dendritic cells on the basis of the presence or absence of the one or more types of molecules. Also disclosed is a method for producing a cell population enriched for regulatory dendritic cells, the method comprising step 1: detecting the presence or absence of one or more types of molecules on a cell surface in a cell population that comprises regulatory dendritic cells; and step 2: obtaining a cell population enriched for regulatory dendritic cells on the basis of the presence or absence of the one or more types of molecules. Further disclosed is a cell population enriched for regulatory dendritic cells obtained by the method.

A device for testing a biological sample includes a housing, two or more test pads, and a sample pad. The sample pad and test pads are disposed within an interior portion of the housing. The sample pad is in fluid communication with an opening defined in an outer surface of the housing for receiving the biological sample. At least a portion of each test pad is in contact with the sample pad and is configured to test the biological sample. At least one window is defined in the outer surface of the housing adjacent the test pads such that the test pads are visible from outside of the housing. A first test pad may detect a threshold amount of CD44 in the biological sample, and a second test pad may detect total protein in the biological sample. The results are then used for early detection of cancers.

A sensor for liquid biopsy, its method of making, and its method of non-invasive use. The sensor includes a substrate with a surface functionalized with biotinylated antibodies. The biotinylated antibodies are arranged to engage with surface proteins on exosomes associated with malignant cancer cells such as glioma cells.

The present invention relates to a biomarker composition for predicting the prognosis of cancer malignancy induced by exposure to microplastics and use thereof, and more particularly, it was confirmed that the expression level of CD44, E-cadherin, N-cadherin, PD-L1, NPAS2, NR1D1, DNMT1, SLC7A2, PCDH7 and CLDN7 was changed in cancer cell lines and animal models treated with polystyrene microspheres which are the one type of microplastic for 4 weeks, and malignancy was induced due to an increase in proliferation, migration and invasion of cancer cells by the change in the expression level of the gene, and 5-year overall survival rates in gastric cancer patients decreased and thus the genes may be provided as a biomarker composition for predicting the prognosis of cancer malignancies by exposure to microplastics.

A nanowires/microscale pyramids (NWs/MPs) substrate complex structure is formed with a plurality of pyramids. Each triangular surface of the pyramid is formed with nanowires to increase the contact area. In one application, anti-epithelial-cell adhesion-molecule (anti-EpCAM) antibodies are modified on the nanowires. The anti-EpCAM antibodies serve to capture circulating tumor cells (CTCs) in blood for determining whether the cancer cells have metastasized to other organs. In another application, the nanowires are modified with silver nanoparticles (AgNPs) which can be combined with other functional groups for testing. The AgNPs on the NWs/MPs substrate causes the NWs/MPs substrate to become a substrate with surface enhanced Raman scattering (SERS). The AgNPs are bound with Epstein-Barr virus (EBV) probe DNA which can be hybridized with EBV target DNAs so as to determine the concentration of the EBV target DNAs in blood. The methods for fabricating the substrate and its applications are also provided.

Provided herein are compositions, methods and uses that relate to or result from the identification of markers that can distinguish between cells at different stages of pluripotency. Certain embodiments provide markers that can distinguish between parental cells (i.e. differentiated cells), partially pluripotent (i.e. partially reprogrammed) and pluripotent (i.e. fully reprogrammed cells). Also provided here are uses of such differential markers, for example, in identification of cell potential, in diagnostics, in differential separation, and in creating efficient workflows that involve fewer steps and lesser time in identifying or separating a desired reprogrammed clone or cell line from a mixture of cells at various stages of pluripotency. In certain embodiments, the activity of these markers can be manipulated to influence cell potential for research or medical purposes.

A system and method for capturing and analyzing a set of cells, comprising: an array including a set of parallel pores, each pore including a chamber including a chamber inlet and a chamber outlet, and configured to hold a single cell, and a pore channel fluidly connected to the chamber outlet; an inlet channel fluidly connected to each chamber inlet of the set of parallel pores; an outlet channel fluidly connected to each pore channel of the set of parallel pores; a set of electrophoresis channels fluidly coupled to the outlet channel, configured to receive a sieving matrix for electrophoretic separation; and a set of electrodes including a first electrode and a second electrode, wherein the set of electrodes is configured to provide an electric field that facilitates electrophoretic analysis of the set of cells.

The methods described herein allow for the classification of patients into groups for receiving optimized radiation treatment based on patient specific biomarker signature. The biomarker signature includes markers that have been shown to correlate with TGF-B expression and to be associated with tumor aggressiveness, radioresistance and poor prognosis. The markers play a key role in the epithelial-mesenchymal transition. The methods described herein provide the dual benefits of anti-tumor efficacy plus normal tissue protection when combining TGF-B inhibitors with ionizing radiation to treat cancer patients.
