Bone marrow (BM) contains a population of self-renewing hematopoietic stem cells (HSC) that give rise to cells from all hemato-lymphopoietic lineages. The concept that HSC could also be plastic and be able to transdifferentiate into stem/progenitor cells for different non-hematopoietic tissues became one of the most controversial issues of modern stem cell biology. Accumulating experimental evidence suggests that contribution of BM-derived stem cells to organ/tissue regeneration could be explained not by plasticity (transdifferentiation) of HSC but rather by the presence of non-hematopoietic stem cells in BM. In this review new evidence will be presented, that adult BM contains a small population of pluripotent very small embryonic-like (VSEL) stem cells. These cells are deposited in BM early during ontogenesis and could be mobilized from BM and circulate in peripheral blood during tissue/organ injury in an attempt to regenerate damaged organs. However, if these cells are mobilized at the wrong time and migrate to the wrong place they may contribute to the development of several pathologies, including tumor formation.

The goal of regenerative medicine is to ameliorate irreversible destruction of brain tissue by harnessing the power of stem cells in the process of neurogenesis. Several types of stem cells, including mesenchymal stem cells, hematopoietic stem cells, as well as neural cells differentiated from embryonic stem cell lines, have been proposed as potential therapeutic vehicles. In this review paper we will discuss a perspective of stem cell therapies for neurological disorders with special emphasis on potential application of cells isolated from adult tissues. In support of this our group found that murine bone marrow contains a mobile population of Oct-4+CXCR4+SSEA-1+Sca-1+lin–CD45– very small embryonic-like stem cells (VSELs) that are mobilized into peripheral blood in a murine stroke model. The number of these cells in circulation increases also after pharmacological mobilization by administration of granulocyte colony stimulating factor (G-CSF). Recently we found that VSELs are present in various non-hematopoietic adult organs and, interestingly, our data indicate that the brain contains a high number of cells that display the VSEL phenotype. Based on our published data both in human and mice we postulate that VSELs are a mobile population of epiblast/germ line-derived stem cells and play an important role as an organ-residing reserve population of pluripotent stem cells that give rise to stem cells committed to particular organs and tissues - including neural tissue. In conclusion human VSELs could be potentially harnessed in regenerative medicine as a source of stem cells for neurogenesis.
