CORNEAL ENDOTHELIAL CELL MARKER

The purpose of the present invention is to provide a method of purification and preparation of cultured corneal endothelial cells, and in particular, to provide cell surface markers for use in corneal endothelial cells not including transformed cells. Provided are cell markers for distinguishing normal cells and transformed cells, in particular normal and transformed corneal endothelium cells. These cell markers relate to specific cell surface markers, for example, to a normal corneal endothelial surface marker such as CD166, and a transformed cell surface marker such as CD73. By using the transformed cell surface marker such as CD73 to remove transformed cells by sorting, it becomes possible to improve purity of a normal cultured corneal endothelium. By using normal corneal endothelial surface marker such as CD166, or by combined use with the transformed cell surface marker, it becomes possible to provide a means for verifying the purity of a prepared corneal endothelium.

The present invention provides an apparatus for analyzing particles in a solution including a unit configured to place a flow cell having a flow path for flowing a sample solution containing the particles; a unit configured to illuminate the sample solution flowing through the flow path of the flow cell; a photodetector that detects a scattered light and/or fluorescence generated from the particles in the sample solution; and a unit configured to analyze the particles based on their signal intensities detected by the photodetector, wherein the flow cell has the flow path formed in a substrate, a reflection plane is formed on the side surface of the flow path, the reflection plane leads the lights generated in the flow path of the flow cell and advancing in the substrate in-plane direction to a specified region of the surface of the flow cell, and the photodetector detects the light exiting from the specified region to the outside.

METHODS AND KITS FOR DETERMINING TUBERCULOSIS INFECTION STATUS

There is provided methods of determining tuberculosis (TB) infection status in an individual comprising: (i) providing a sample comprising T-cells; (ii) exposing the sample of (i) to one or more TB antigens; (iii) identifying T-cells in the sample that are CD4 positive and (a) secrete TNF-α without secreting IFN-γ; or (b) secrete IFN-γ without secreting TNF-α; (iv) identifying those cells of (iii) which are also CCR7 and, CD127 negative; and optionally (v) calculating the cells identified in (iv) as a percentage of those identified in (iii); wherein the identification of cells in (iv) and/or the percentage of T-cells calculated in (v) correlates to TB infection status of the individual, and wherein steps (iii) and (iv) can be carried out either sequentially or simultaneously. There are also provided compositions and kits for use in such methods.

METHODS OF MEASURING POTENTIAL FOR THERAPEUTIC POTENCY AND DEFINING DOSAGES FOR AUTOLOGOUS CELL THERAPIES
20210164978 · 2021-06-03 · ·

Autologous bone marrow cells (BMC) are transplanted to a heterologous site in a patient after a sample of the patient's BMC has been tested and found to have a phenotypic profile which meets minimum criteria for transplantation. The phenotypic profile may be obtained by screening a sample of bone marrow cells (BMC) from the patient for the phenotypic profile, such as a CD profile, the phenotype profile may be assessed to determine the likelihood that the BMC will be suitable for transplantation to the heterologous tissue site without enriching particular phenotypic population(s) of the BMC.

Use of SUSD2 protein as marker

SUSD2 protein is used as a marker in identification, selection or separation of pancreatic internal secretion precursor cells and/or newborn pancreatic internal secretion cells; and a use of an mRNA, for encoding the SUSD2 protein, of a precursor protein as the marker in identification of the pancreatic internal secretion precursor cells and/or the newborn pancreatic internal secretion cells. Analysis of gene expression of pancreatic endoderm cells sourced by induced directional differentiation of human pluripotent stem cells finds the enrichment expression of a SUSD2 gene in the pancreatic internal secretion precursor cells and the newborn pancreatic internal secretion cells. A protein encoded by the SUSD2 gene is a receptor protein on cell membranes. Using the protein as the marker, the identification, the selection or the separation of the pancreatic internal secretion precursor cells and the newborn pancreatic internal secretion cells can be conducted.

Markers capable of distinguishing cell pluripotency and uses thereof

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.
