7 results about "Lineage specific" patented technology

The present invention relates to the field of stem cell biology, in particular the linage specific differentiation of pluripotent or multipotent stem cells, which can include, but is not limited to, human embryonic stem cells (hESC), human induced pluripotent stem cells (hiPSC), somatic stem cells, cancer stem cells, or any other cell capable of lineage specific differentiation. Specifically described are methods to direct the lineage specific differentiation of hESC and / or hiPSC to nociceptors (i.e. nociceptor cells) using novel culture conditions. The nociceptors made using the methods of the present invention are further contemplated for various uses including, but limited to, use in in vitro drug discovery assays, pain research, and as a therapeutic to reverse disease of, or damage to, the peripheral nervous system (PNS). Further, compositions and methods are provided for producing melanocytes from human pluripotent stem cells for use in disease modeling.

Animal cells, notably adult fibroblasts, are advantageously reprogrammed in direct lineage reprogramming methods using defined factors to produce proliferative and multipotent induced cardiac progenitor cells (iCPC). The iCPC thus produced can be differentiated under suitable differentiation conditions to cardiac lineage cells including cardiomyocytes, smooth muscle cells, and endothelial cells, as evidenced by expression of lineage specific markers. Sets of factors effective in combination to reprogram the fibroblasts can include a set that includes some or all of 5 factors (Mespl, Baf60c, Nkx2.5, Gata4, Tbx5), a set that includes some or all of 11 factors (Mespl, Mesp2, Gata4, Gata6, Baf60c, SRF, Isll, Nkx2.5, Irx4, Tbx5, Tbx20), a set that includes some or all of 18 factors (T, Mespl, Mesp2, Tbx5, Tbx20, Isll, Gata4, Gata6, Irx4, Nkx2.5, Handl, Hand2, Tbx20, Tbx18, Tip60, Baf60c, SRF, Hey2), and a set that includes some or all of 22 factors (T, Mespl, Mesp2, Tbx5, Tbx20, Isll, Gata4, Gata6, Irx4, Nkx2.5, Hand1, Hand2, Tbx20, Tbx18, Tip60, Baf60c, SRF, Hey2, Oct4, Klf4, Sox2, L-myc).

Well-defined, xeno-free culture media which comprise a TGF-beta isoform or the chimera formed between IL6 and the soluble IL6 receptor (IL6RIL6), which are capable of maintaining stem cells, and particularly, human embryonic stem cells, in an undifferentiated state are provided. Also provided are cell cultures comprising the culture media and the stem cells and methods of expanding and deriving embryonic stem cells in such well-defined, xeno-free culture media. In addition, the present invention provides methods of differentiating ESCs or EBs formed therefrom for the generation of lineage specific cells.

To provide methods of lineage specific differentiation of pluripotent stem cells, including induced pluripotent stem cells, into floor plate midbrain progenitor cells, determined dopamine (DA) neuron progenitor cells, and / or DA neurons.SOLUTION: Provided is a method of differentiating neural cells, the method comprising: (a) performing a first incubation comprising culturing pluripotent stem cells in a non-adherent culture vessel under conditions to produce a cellular spheroid; and (b) performing a second incubation comprising culturing cells of the spheroid in a substrate-coated culture vessel under conditions to neurally differentiate the cells.SELECTED DRAWING: Figure 1
