1. A method for culturing a stem or progenitor cell, which method comprises:
- (a) adding, to a culture of stem or progenitor cells, a sustained release composition comprising at least one growth factor that maintains the cells in an undifferentiated state; and
(b) repeating the step of adding the sustained release composition such that the cells are maintained in an undifferentiated state.

Abstract
Methods for culturing undifferentiated mammalian cells, such as stem and progenitor cells, are provided. The methods involve incubating the cell in the presence of a sustained release composition containing at least one growth factor, wherein the sustained release composition continuously releases the growth factor(s), and wherein the presence of the sustained level of growth factor maintains the cell in an undifferentiated state.
