Abstract:
The disclosure relates to compositions comprising hematopoietic cells and methods of using the same. The disclosure also relates to methods of reprogramming endothelial cells into hematopoietic cells by exposing the endothelial cells to at least one hematopoietic effector.
Abstract:
This disclosure relates to growth media and environments for in vitro culturing of cells that produce or are capable of producing antibodies. In certain embodiments, the media comprises IL-6, fibronectin, and typically a saccharide. In certain embodiments, the disclosure contemplates cell culture compositions comprising IL-6 and fibronectin that are derived from proteins secreted from mesenchymal stromal/stem cells (MSCs). In certain embodiments, the disclosure contemplates enclosures comprising culture compositions disclosed herein that are in ambient air or optionally in an environment wherein oxygen is absent or at a low concentration.
Abstract:
The present invention relates to a method of culturing primitive-like macrophages from stem cells, a kit when used in the method thereof and uses of the primitive like macrophage for in-vitro disease models and for screening compounds for therapy. One embodied culture method comprises contacting and incubating embryonic stem cells or induced pluripotent stem cells with a serum-free culture media comprising a GSK3 inhibitor to differentiate stem cells into cells of the mesoderm lineage, followed by incubation with a culture media comprising Dickkopf-related protein 1 (DKK1) to differentiate the mesoderm into cells of hematopoietic lineage, maturing hematopoietic cells and incubating these cells with a culture media comprising M-CSF to drive differentiation into primitive-like macrophages. Another embodiment comprises incubating the stem cells with serum-free culture media comprising FGF2 and BMP4 to induce differentiation into cells of the mesoderm lineage, followed by incubating the cells with a culture media comprising FGF2, BMP4, Activin A and VEGF to differentiate the cells of the mesoderm lineage into cells of the hematopoietic cell lineage, maturing the cells of the hematopoietic cell lineage and lastly, incubating the matured hematopoietic cells with culture media comprising M-CSF to drive the differentiation of hematopoietic cells into primitive-like macrophages.
Abstract:
The present disclosure relates to genetically modified B cells, including memory cells, differentiated to plasmablasts or plasma cells useful for long term in vivo expression of a transgene, such as a specific antibody or other protein therapeutic. Also disclosed are methods of producing the cells and methods of treatment.
Abstract:
The present invention provides a method for preparing a cell culture medium comprising a mixture of blood products from two or more donors, comprising the steps of: a) providing at least a first blood product from a first donor; b) measuring the concentration of at least one quality factor in the first blood product; c) comparing the measured concentration of a quality factor to a concentration range predefined for the quality factor; d) selecting the first blood product for the cell culture medium if the concentration measured for the quality factor is in the predefined range and optionally converting the first selected blood product into a first processed blood product or else unselecting the first blood product.
Abstract:
The current disclosure describes methods of expanding precursor cells for hematopoietic transplantation in subjects. The methods culture precursor cells in media containing an immobilized high molecular weight LILRB2 agonist or an LILRB2 agonist in combination with a Notch agonist. The expanded cells can be used to treat a variety of hematopoietic disorders.
