Marrow Stromal Cells as Stem Cells for Nonhematopoietic Tissues
Darwin J. Prockop
Marrow stromal cells can be isolated from other cells in marrow by
their tendency to adhere to tissue culture plastic. The cells have many
of the characteristics of stem cells for tissues that can roughly be
defined as mesenchymal, because they can be differentiated in culture
into osteoblasts, chondrocytes, adipocytes, and even myoblasts.
Therefore, marrow stromal cells present an intriguing model for
examining the differentiation of stem cells. Also, they have several
characteristics that make them potentially useful for cell and gene
therapy.
