摘要:
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.

A method of producing a lens cell is disclosed. The method includes: an ES cell maintenance step of maintaining an ES cell by using a medium containing a fibroblast growth factor FGF-2 at a concentration of 2 ng/ml to 50 ng/ml; and a differentiation inducing step, carried out after the ES cell maintenance step, of inducing differentiation of the ES cell into a lens cell by implanting and culturing the ES cell on a mouse-skull-cell PA6 at a cell density of 2 colonies/cm2 to 6.5 colonies/cm2. In one embodiment, a washing step, carried out between the ES cell maintenance step and the differentiation inducing step, of washing the maintained ES cell once with an ES differentiation medium is included.

摘要:
The present invention is directed to methods of repairing damaged or diseased, specialized or differentiated tissue in mature animals, particularly neuronal tissue such as retinas. In particular, the invention relates to transplantation of adult, hippocampus-derived progenitor cells into a selected neural tissue site of a recipient. These cells can functionally integrate into mature and immature neural tissue. The invention encompasses, in one aspect, repopulating a retina of a dystrophic animal with neurons, by injecting clonally derived, adult central nervous system derived stem cells (ACSC) derived from a healthy donor animal into an eye of the dystrophic recipient. Herein disclosed is the first successful and stable integration of clonally derived ACSC into same-species but different strain recipients (e. g., Fischer rat-derived adult hippocampal derived progenitor cells (AHPCs) into dystrophic RCS rats). Surprisingly, AHPCs were also found to integrate successfully into a xenogeneic recipient (e.g., rat AHPCs into the retina of dystropic rd-I mice).

The present invention provides a method of producing primate retinal progenitor cells, comprising culturing primate embryonic stem cells as suspended aggregates in a serum-free medium, and obtaining retinal progenitor cells from the culture. The present invention further provides a method of producing photoreceptor precursor cells, comprising culturing isolated retinal progenitor cells differentiated from embryonic stem cells, under adhesive conditions, in the presence of a gamma secretase inhibitor, and obtaining a photoreceptor precursor from the culture.
