BACKGROUND & AIMS Liver transplantation is the primary treatment for various end-stage hepatic diseases but is hindered by the lack of donor organs and by complications associated with rejection and immunosuppression. There is increasing evidence to suggest the bone marrow is a transplantable source of hepatic progenitors. We previously reported that multipotent bone marrow-derived mesenchymal ...

the biological interaction between the jaw bones and dental implant is fundamental for the long-term success of dental implant placement. nevertheless, the insufficient bone volume remains a major clinical problem, especially in case of immediate dental implant. using a canine model, the present study proves the regenerative potential of adipose- derived stem cells (adscs) to repair peri-implan...

Studies on hematopoiesis have focused on the function and composition of human bone marrow stroma. Stroma function gives hematopoietic stem cells the microenvironment appropriate for self-renewal and/or prompt differentiation into hematopoietic progenitor cells, then into terminal specialized cells. Human bone marrow stroma has been dissected into hematopoietic and nonhematopoietic components. ...

Over the last decade, stem/progenitor-cell therapy has emerged as an innovative approach to provide cardiac repair and regeneration (Zimmermann, et al., 2006). Several stemand progenitor-cell types from autologous and allogeneic donors have been analyzed to find the most appropriate candidate. Although embryonic stem (ES) cells can differentiate into most cardiac cell types (Mummery, et al., 20...

Lung injury is a common cause of death and disability. Stem cell-related therapies are widely viewed as offering promise for people suffering from various types of pulmonary diseases, and gender-mismatched bone marrow transplant recipients serve as natural populations in which to study the role of bone marrow-derived stem cells in recovery from pulmonary injury. We evaluated the extent of lung ...

Spermatogenesis is a self-renewing process leading to production of spermatozoa in adult testis. The existence of male germinal stem cells was demonstrated by regeneration of spermatogenesis after transplantation of total testicular germ cells in testis [1], and we have previously shown that mouse testicular cells contain a side population (SP) of stem cells (Hoechst 33342 fluorescent dye efflu...

The generation of neuronal cells from stem cells obtained from adult bone marrow is of significant clinical interest in order to design new cell therapy protocols for several neurological disorders. The recent identification in adult bone marrow of stem cells derived from the neural crests (NCSCs) might explain the neuronal phenotypic plasticity shown by bone marrow cells. However, little infor...
