  • Patent number: 10612094
    Abstract: The present invention provides genetic markers for identifying engraftable human cardiac ventricular progenitor cells. The engraftment markers of the invention include angiogenic markers and extracellular matrix markers. Human ventricular progenitor cells expressing these markers are capable of forming ventricular tissue in vivo that is vascularized and supported by an extracellular matrix. Methods of engrafting human cardiac ventricular progenitor cells by transplanting into a subject progenitor cells that express the engraftment markers are also provided.

  • Patent number: 10590390
    Abstract: The present invention relates to a method for preparing highly pure pancreatic progenitor cells by using pluripotent stem cells such as ES cells or iPS cells as a source, inducing their differentiation into pancreatic progenitor cells, and culturing and proliferating the pancreatic progenitor cells. Specifically, the present invention relates to a method for proliferation of pancreatic progenitor cells, comprising the step of culturing the pancreatic progenitor cells in a medium containing (i) an EGF signal transduction activator and/or an FGF signal transduction activator and (ii) a ROCK inhibitor.

  • Patent number: 10527631
    Abstract: Methods and compositions are provided for the selective activation of a BMP-dependent response in certain cell types. Methods include identifying a ligand or ligand combinations as well as cell receptor profiles that result in selectively activating a ligand-dependent response through interactions with ligand receptors on a first cell type that do not activate the ligand-dependent response in a second cell type.

  • Patent number: 10519422
    Abstract: The invention relates to a method of producing a retinal pigment epithelial cell from a human pluripotent stem cell, and a method of treating or preventing a retinal disease by using the produced cell. The retinal pigment epithelial cell is prepared by (a) inducing differentiation of a human pluripotent stem cell into a pigment cell by adhesion cultivation of a human pluripotent stem cell in a medium containing a Nodal signal inhibitor and a Wnt signal inhibitor in the absence of a feeder cell to give a culture containing the pigment cell, (b) subjecting the obtained culture to further adhesion culture to give a culture containing a pigment cell colony, and (c) isolating the pigment cell from the obtained culture and culturing the cell to give a retinal pigment epithelial cell.

  • Patent number: 10513685
    Abstract: Provided is a method that achieves control of embryoid body size and can induce differentiation in a state where the embryoid body size is controlled, by using a cell culture chamber having a plurality of microchambers formed therein. A culture method for causing differentiation of pluripotent mammalian cells uses a cell culture chamber (10) having a plurality of microchambers (11) formed on a culture surface. The cell culture chamber (10) has a culture surface formed of spaces in which the microchambers (11) have a space structure with a height of 10 ?m to 500 ?m and a bottom area of 100 ?m2 to 1 mm2. The culture method for causing differentiation of pluripotent mammalian cells includes culturing pluripotent mammalian cells to obtain a cell population at least partially differentiated into endoderm lineage cells, by using the cell culture chambers (10).
