摘要:
The present disclosure provides a method of producing and expanding human pancreas progenitor cells using, for example, iPSC derived cells and a human feeder cell conditioned medium. In one embodiment, cardiac mesenchyme cells are employed as feeder cells and those cells secrete growth factors, such as one or more of FGF10, KGF, or EGF, that promote pancreatic bud formation and expansion during development. In one embodiment, feeder cells are isolated from human stem cells, e.g., a human iPS-derived cardiac cells, and used to condition media and promote the growth and proliferation of iPSc derived pancreatic progenitor cells (in a feeder-free system).

The invention relates to improved culture methods for expanding epithelial stem cells and obtaining organoids, to culture media involved in said methods,and to uses of said organoids.
摘要:
The present invention relates to a method for the production of differentiated respiratory epithelial cells comprising: (a) providing a cell population comprising or consisting of precursor cells of respiratory epithelial cells; (b) culturing the cell population of (a) in culture medium to which keratinocyte growth factor has been added; wherein the cultured cell population is supplemented with a glucocorticoid, a cAMP analogue and a cAMP elevating agent and wherein said supplementation is either simultaneously with the addition of keratinocyte growth factor in step (b) or prior or subsequently to the addition of keratinocyte growth factor in step (b), thereby differentiating said precursor cells into respiratory epithelial cells. The present invention further relates to the cell(s) obtained by the method of the invention for use in treating or preventing a respiratory disease and to a method for identifying a compound having an pharmacological, cytotoxic, proliferative, transforming or differentiating effect on the differentiated respiratory epithelial cells obtained by the method of the invention.
摘要:
The present invention provides methods to promote the differentiation of pluripotent stem cells into insulin producing cells. In particular, the present invention provides a method to produce cells expressing markers characteristic of the pancreatic endocrine lineage that co-express NKX6.1 and insulin and minimal amounts of glucagon.

The present invention relates to methods for encapsulating pancreatic progenitors in a biocompatible semi-permeable encapsulating device. The present invention also relates to production of human insulin in a mammal in response to glucose stimulation.
摘要:
The present invention provides a method for increasing the expression of MAFA in cells expressing markers characteristic of the pancreatic endocrine lineage comprising the steps of culturing the cells expressing markers characteristic of the pancreatic endocrine lineage in medium comprising a sufficient amount of a cyclin-dependant kinase inhibitor to cause an increase in expression of MAFA.
摘要:
Disclosed herein are methods for generating endoderm lineage type cells derived from human pluripotent cells, such as human embryonic stem cells, by using various agents including, but not limited to, GDF8, GDF11 and GSK-3beta inhibitors. Also disclosed herein are endoderm lineage cell populations or compositions, such as populations or compositions comprising definitive endoderm and/or other definitive endoderm-derived cell types.
