Stem cell regulatory niches and their role in normal and malignant hematopoiesis.

abstract：:Stem cells continue to attract considerable attention and provide hope for the development of new cell-based therapies for degenerative diseases. Unlocking the full therapeutic potential of stem cells requires an understanding of the mechanisms by which they are generated, self-renew, and differentiate. The applicatio...
