Cells previously identified as retinal stem cells are pigmented ciliary epithelial cells.
It was previously reported that the ciliary epithelium (CE) of the mammalian eye contains a rare population of cells that could produce clonogenic self-renewing pigmented spheres in culture. Based on their ability to up-regulate genes found in retinal neurons, it was concluded that these sphere-forming cells were retinal stem cells. This conclusion raised the possibility that CE-derived retinal...
متن کاملWhat are Stem Cells?
Stem cells are undifferentiated self regenerating multi potential cells. There are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. Totipotent: these stem cells can form an entire organism such as fertilized egg. Ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organ...
متن کاملSwelling-activated potassium channel in porcine pigmented ciliary epithelial cells.
PURPOSE Ion channels in the ciliary epithelium play critical roles in the formation of aqueous humor in the eye. The present study identified a novel, swelling-activated K(+) current in freshly dissociated porcine pigmented ciliary epithelial cells. METHODS Ciliary epithelial cells were freshly dissociated from porcine eyes. Whole-cell currents were recorded by the patch-clamp technique in pi...
متن کاملIsolation of non-pigmented epithelial cells from rabbit ciliary body.
We describe a new technique for the separation and isolation of nonpigmented ciliary body epithelial cells from rabbit. Excised ciliary body is incubated in a medium buffered with EGTA to a free-Ca2+ concentration of 10(-8) M, and the nonpigmented cell layer is separated from the pigmented layer by microdissection under direct visualization. This technique yields intact cells which are greater ...
