<unk> s or<unk> s are multipotent stem<unk> s that can differentiate into a variety of<unk>  types.<unk>  types that<unk> s have been shown to differentiate into in vitro or in vivo include osteoblasts, chondrocytes, myocytes, adipocytes, and as described lately, into beta-pancreatic islets<unk> s. They can also transdifferentiate into  neuronal<unk> s.
While the terms<unk>  and Marrow Stromal<unk>  have been used interchangeably, neither term is sufficiently descriptive as discussed below:
Mesenchyme is embryonic connective tissue that is derived from the mesoderm which differentiates into hematopoietic and connective tissue, whereas<unk> s do not differentiate into hematopoietic<unk> s.
Stromal<unk> s are connective tissue<unk> s which form the supportive structure in which the functional<unk> s of the tissue reside. While this is an accurate description for one function of<unk> s, the term fails to convey the relatively recently discovered roles of<unk> s in repair of tissue.
Because the<unk> s called<unk> s by many labs today can encompass multipotent<unk> s derived from other non-marrow tissues, such as adult muscle side-population<unk> s or the Wharton's jelly present in the umbilical cord as well as in the dental pulp of deciduous baby teeth, yet do not have the capacity to reconstitute an entire organ, the term Multipotent Stromal<unk>  has been proposed as a better replacement.
