Abstract
Described here are three-dimensional microenvironment niches prepared from biomaterial compositions that support growth and self renewal of stem cells. The invention also provides methods for inducing pluripotency in a somatic cell using chemical compounds, as well as methods for screening for compounds that can induce pluripotency in a somatic cell.
