METHODS FOR CULTURING STEM AND PROGENITOR CELLS
20220252604 · 2022-08-11 ·

The present application describes a method of culturing, expanding or growing stem or stem-like cells or induced pluripotent stem cells on a surface, including attaching the cells to the surface through a ligand that binds to the surface and the cells.

BROWN ADIPOCYTE PROGENITORS IN HUMAN SKELETAL MUSCLE
20220228119 · 2022-07-21 ·

This invention relates to brown adipose tissue (BAT) progenitor cells and methods for isolating BAT progenitor cells from skeletal muscle. BAT progenitor cell surface markers and medium and agents for inducing cell differentiation into brown adipocytes are also provided. In some embodiments, the BAT progenitor cell expresses a first cell surface marker associated with endothelial cells, the first cell surface marker being detectable in an antibody based assay using a first antibody. In addition, the BAT progenitor cell can be substantially free of a second cell surface marker associated with endothelial cells, the second cell surface marker being substantially undetectable in said antibody based assay using a second antibody. The BAT progenitor cell can also be substantially free of additional cell surface markers.

METHODS FOR IDENTIFYING BETA-GLUCAN BINDING TO IMMUNE CELLS

This disclosure describes, in one aspect, a method for identifying β-glucan binding to immune cells of a subject. Generally, the method includes obtaining a blood sample from the subject, the blood sample comprising immune cells, adding soluble β-glucan to at least a portion of the blood sample and incubating the mixture under conditions allowing the soluble β-glucan to bind to the immune cells, and detecting soluble β-glucan hound to the immune cells. In another aspect, this disclosure describes a method that generally includes identifying the subject as a low binder of β-glucan, and co-administering to the subject a soluble β-glucan and an antibody preparation capable of converting the subject from a low binder to a high binder.
