Method for predicting effect of drug
A method for predicting an effect of a medication or a treatment regimen to a subject suffering from a cancer, the method comprises: (A) obtaining a tissue from the subject; (B) dissociating the tissue to obtain a multicellular cluster, wherein the multicellular cluster comprises the cancer cell; (C) culturing the multicellular cluster on a cellulose sponge; (D) exposing the cultured multicellular cluster to the medication or the treatment regimen; and (E) measuring a first survival rate of the cancer cell before exposing to the medication or the treatment regimen and a second survival rate of the cancer cell after exposing to the medication or the treatment regimen, when the second survival rate is lower than the first survival rate, the method predicts positive effect of the medication or the treatment regimen to the subject.
Composition and Methods for Producing Insulin Producing Islet Cells
Disclosed herein are compositions and methods to differentiate pancreatic cells into functional insulin-producing CD133/KI-67-positive activated islet proliferating cells (AIPCs) derived from isolated pancreatic islets and expand derived-AIPCs in in vitro cultures using a culture medium comprising an active agent. Also disclosed herein is the use of the AIPCs for implantation into a mammal for in vivo therapy, specifically for pancreatic disorders, including diabetes type I.
PANCREATIC ENDOCRINE PROGENITOR CELL THERAPIES FOR THE TREATMENT OF OBESITY AND TYPE 2 DIABETES (T2D)
Provided herein are therapies, and methods using that therapy, in the treatment of one or more of Type 2 diabetes (T2D), obesity, glucose intolerance and insulin resistance or to control weight gain in subjects. In particular, the subject may be candidates for treatment with one or more small molecule anti-diabetic drugs and the therapy may include implanting a population of pancreatic endocrine progenitor cells into the subject, where the cells are allowed to mature in vivo to produce a population.
ORAL DISSOLVING FILMS CONTAINING MICROENCAPSULATED VACCINES AND METHODS OF MAKING SAME
An oral dissolving film containing nano- or micro-encapsulated bioactive material and methods of forming the film. The film may be prepared by dispensing a mixture of a film-forming agent, a crosslinking agent, a solution of nano- or micro-encapsulated bioactive material, and a photoinitiator into a plurality of wells in a tray using a 3D printer. The dispensed material is exposed to radiation in order to crosslink the material and form a film.
PANCREATIC CELLS FOR TREATING DIABETES AND METHODS OF GENERATING THE SAME
The present disclosure provides cell-based compositions for treating diabetes, methods for identifying cells that preferentially differentiate into endoderm cells, and methods for preparing insulin-producing pancreatic cells, as well as related methods of use for treating diseases related to insulin deficiency.
METHODS OF USE OF ISLET CELLS
Type 2 diabetes (T2D) is a clinical syndrome caused by insufficient insulin secretion for insulin requirements. described herein are compositions and methods for microphysiological MPS models of disease (MODs) for diabetes. These platforms allow one to compare the effect of chronic -cell stimulation in the presence and absence of patient specific immune cells in IPSC-derived islets from each group. Additionally, one can reproduce the T2D -cell phenotype, using islets-on-chips will also be exposed to gluco-lipotoxicity. Likewise, skeletal muscle-on-chips are exposed to patient specific activated immune cells, variable motor neuron innervation and lipids characteristic of T2D.
MICROENVIRONMENTS FOR SELF-ASSEMBLY OF ISLET ORGANOIDS FROM STEM CELLS DIFFERENTIATION
Human pluripotent stem cells (hPSCs) are promising cell source to produce therapeutic endocrine cells for diabetes treatment. A gel solution made by decellularized tissue-specific extracellular matrix (dpECM) significantly promotes three-dimensional (3D) islet-like organogenesis during induced hPSC differentiation into endocrine lineages. Islet organoids are self-organized even in a two-dimensional (2D) culture mode. Cells derived from hPSCs differentiated on such ECM coated substrates exhibit similar cellular composition to native pancreatic islets. These cells express islet signature markers insulin, PDX-1, C-peptide, MafA, glucagon, somatostatin, and pancreatic polypeptide, and secrete more insulin in response to glucose level compared to a traditional matrix substrate (Matrigel). The dpECM facilitates generating more C-peptide+/glucagon cells rather than C-peptide+/glucagon+ cells. Remarkably, dpECM also facilitated intra-organoid vascularity by generating endothelial cells and pericytes. Furthermore, dpECM niches also induced intra-organoid microvascularization during pancreatic differentiation.
