Modulation of Microglia Activation
The invention provides methods for treating pathological conditions associated with an undesirable inflammatory component. The invention is generally directed to reducing inflammation by administering cells that modulate microglia activation. The invention is also directed to drug discovery methods to screen for agents that modulate the ability of the cells to modulate microglia activation. The invention is also directed to cell banks that can be used to provide cells for administration to a subject, the banks comprising cells having desired levels of potency to modulate microglia activation.
1 . A method for treating inflammation in a subject having a condition, the method comprising selecting cells that have a desired potency for modulating microglia activation, assaying the selected cells for the desired potency, and administering the cells having the desired potency to the subject, in a therapeutically effective amount and for a time sufficient to achieve a therapeutic result, the cells being non-embryonic stem, non-germ cells that express one or more of oct4, telomerase, rex-1, or rox-1 and/or can differentiate into cell types of at least two of endodermal, ectodermal, and mesodermal germ layers.
2 . A method for treating inflammation in a subject having a condition, the method comprising administering cells having a desired potency for modulating microglia activation to the subject, in a therapeutically effective amount and for a time sufficient to achieve a therapeutic result, the cells being non-embryonic stem, non-germ cells that express one or more of oct4, telomerase, rex-1, or rox-1 and/or can differentiate into cell types of at least two of endodermal, ectodermal, and mesodermal germ layers, wherein, prior to administration, the cells were validated as having the desired potency.
3 . A method for modulating microglia activation in a subject having a condition, the method comprising selecting cells that have a desired potency for modulating microglia activation, assaying the cells for the desired potency, and administering the cells having the desired potency to the subject, in a therapeutically effective amount and for a time sufficient to achieve a therapeutic result, the cells being non-embryonic stem, non-germ cells that express one or more of oct4, telomerase, rex-1, or rox-1 and/or can differentiate into cell types of at least two of endodermal, ectodermal, and mesodermal germ layers.
