Abstract:
A method for producing an antibody fragment from one or more single plasma cells. The method comprises obtaining a plurality of plasma cells, preparing a plurality of modified cell culture substrates, seeding each respective plasma cell of the plurality of plasma cells on the each respective modified cell culture substrate of the plurality of modified cell culture substrates, forming a plurality of cultured single plasma cells by culturing the seeded each respective plasma cell in a culture medium for a time duration of at least 10 days, and detecting the one or more single plasma cells that secrete the antibody fragment from among the plurality of cultured single plasma cells. The culture medium comprises a conditioned medium harvested from a culture of h-BMSCs, Insulin, Transferrin, Selenium, and Pyruvate.
Abstract:
The invention relates to an ex vivo generated population of tissue-specific anti-inflammatory macrophages and methods of making and using such macrophages.
Abstract:
The present invention provides a highly functional hypoimmunogenic cell, namely, a hypoimmunogenic human cell
(1) lacking an endogenous gene encoding an α chain of human leukocyte antigen (HLA) class Ia, (2) lacking an endogenous gene encoding HLA class II or an expression regulator thereof, (3) containing an exogenous gene encoding an α chain of HLA class Ib, (4) containing an exogenous gene encoding human PD-L1, and (5) containing an exogenous gene encoding human PD-L2.
Abstract:
The invention relates to a method of producing CD34+CD4dim megakaryocyte (MK) progenitor cells, and substantially pure cell population of megakaryocyte precursor cells obtained by said method. The invention also relates to a method of producing proplatelet-bearing MKs and/or platelets using the CD34+CD4dim cells.
Abstract:
A 3D in vitro bi-phasic cartilage-bone organoid includes a layer of an artificial cartilage tissue, and a layer of an artificial bone tissue comprising a structure-giving scaffold and a bone marrow structure. The layer of the artificial cartilage tissue contacts at least one surface of the layer of the artificial bone tissue.
Abstract:
Various embodiments of the invention provide methods of treating diabetes and other glucose regulation disorders. In one embodiment, the method comprises removing L-cells from a donor, obtaining stem cells from a patient, and culturing the L-cells in the presence of the stem cells under conditions such that the stem cells differentiate into stem cell-derived L-cells (SCDLC). An amount of the SCDLC is introduced into the patient sufficient to cause a lowering of the patient's blood glucose level after ingestion of food. In another embodiment, the method comprises removing K-cells from a donor, obtaining stem cells from a patient, and culturing the K-cells in the presence of the stem cells under conditions such that the stem cells differentiate into stem cell-derived K-cells (SCDKC). An amount of the SCDKC is introduced into the patient sufficient to cause a lowering of the patient's blood glucose level after ingestion of food.
Abstract:
Described herein are 3-dimensional clusters of reaggregated cells comprising cells reaggregated from at least two different cell sources, such as different cell types, different donors, and combinations thereof. Methods of making, using, and cryopreserving these 3-dimensional clusters of reaggregated cells are also described herein.

Abstract:
Described are Neo-Islets comprising: a) dedifferentiated islet cells and mesenchymal and/or adipose stem cells; or b) redifferentiated islet cells and mesenchymal and/or adipose stem cells where the cells have been treated so as to facilitate redifferentiation. Further described herein are methods of generating Neo-Islets, the methods comprising: culturing a) dedifferentiated islet cells and mesenchymal and/or adipose stem cells; or b) redifferentiated islet cells and mesenchymal and/or adipose stem cells; on a surface that promotes the formation of cell clusters. Also described are methods of treating a subject, the methods comprising: providing to the subject Neo-Islets described herein. Additionally described are methods of treating a subject suffering from Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus, and other types of insulin-dependent diabetes mellitus, or impaired glucose tolerance by providing to the subject Neo-Islet as described herein. Additionally described are methods of treatment in which intraperitoneal administration of islet-sized Neo-Islets composed of high numbers of mesenchymal stem cells and cultured islet cells, durably and reversibly treats, without hypoglycemia, both streptozotocin-induced and spontaneous Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus, and other types of insulin-dependent diabetes mellitus, or impaired glucose tolerance.
Abstract:
A method is described for generating a novel cancer stem cell line that possesses characteristics associated with stem cells, by co-culturing a human immortalized cell line and bone marrow-derived mesenchymal stem cells, and the novel cancer stem cell line established thereby. This method is able to readily generate cancer stem cells that are low in the level of structural chromosomal aberrations and are excellent in oncogenicity, and is effectively applicable to the development of anti-cancer drugs and personalized drugs.
