PRIMARY BREAST EPITHELIAL CELL CULTURE MEDIUM, CULTURE METHOD AND USE THEREOF
Provided is a culture medium containing amphiregulin for culturing primary breast epithelial cells and a culture method involving using the medium. In the culturing method, primary cells are cultured on a culture vessel coated with an extracellular matrix gel by using the culture medium, and the primary cells grow on the culture vessel, which has been coated with the extracellular matrix gel, and proliferate rapidly under the combined action of nutrient factors and an extracellular matrix contained in the primary cell culture medium. The cell model obtained by the primary cell culture medium and the primary cell culture method can be used for the evaluating the efficacy of and screening drugs.
Method for Producing Brown Adipocytes
The present invention is primarily directed to provide a new process capable of performing direct conversion of or induction from a somatic cell to brown adipocytes with low molecular weight compounds, without performing artificial gene transfer.
The present invention includes, for example, a process for producing brown adipocytes by direct differentiation induction from somatic cells, comprising a step of culturing a somatic cell in a serum-free differentiation induction medium in the presence of a selective PPARγ agonist and a cAMP inducer.
According to the present invention, direct conversion of or induction from somatic cells to brown adipocytes can be effectively performed without gene transfer. The brown adipocytes obtained by the present invention are useful as regenerative medicine, models of human brown adipocytes and human beige cells, and the like.
Composition for Medium
The present invention is primarily directed to provide a new composition for a medium which can be used for differentiation induction from somatic cells to brown adipocytes.
The present invention can include, for example, a composition for a medium used in differentiation induction from somatic cells to brown adipocytes, wherein the composition comprises the following seven components: a thyroid hormone receptor agonist, a glucocorticoid receptor agonist, a phosphodiesterase inhibitor, insulin, an ascorbic acid derivative, albumin, and an antibiotic.
According to the present invention, direct differentiation induction from somatic cells to brown adipocytes can be effectively performed. In addition, according to the present invention, it is possible to effectively maintain brown adipocytes.

GENERATION OF HUMAN PLURIPOTENT STEM CELL DERIVED FUNCTIONAL BETA CELLS SHOWING A GLUCOSE-DEPENDENT MITOCHONDRIAL RESPIRATION AND TWO-PHASE INSULIN SECRETION RESPONSE
The invention provides for methods of differentiating pancreatic endocrine cells into pancreatic beta cells expressing PDX1, NKX6.1, MAFA, UCN3 and SLC2A. These pancreatic beta cells may be obtained by step-wise differentiation of pluripotent stem cells. The pancreatic beta cells exhibit glucose-dependent mitochondrial respiration and glucose-stimulated insulin secretion similar to islet cells.
METHODS FOR DIFFERENTIATING PLURIPOTENT STEM CELLS IN DYNAMIC SUSPENSION CULTURE
Methods for differentiating pluripotent stem cells to neuroectoderm in dynamic suspension culture using small molecule or protein inhibitors of TGFβ/Activin/Nodal signaling and BMP signaling are provided.
