BACKGROUND We previously established a mesenchymal stem cell line (FMS/PA6-P) from the bone marrow adherent cells of fetal mice. The cell line expresses a higher level of neural cell adhesion molecule and shows greater hematopoiesis-supporting capacity in mice than other murine stromal cell lines. DESIGN AND METHODS Since there is 94% homology between human and murine neural cell adhesion mol...

BACKGROUND The complex process by which lactation is initiated upon neonate delivery remains incompletely understood. Microvesicles (MVs) can transmit microRNAs (miRNAs) into recipient cells to influence cell function, and recent studies have identified miRNAs essential for mammary gland development and lactation. This study aimed to investigate the expression of lactation-related miRNAs in MVs...

Rare hematopoietic stem cell populations are responsible for the transplantation engraftment process. Umbilical cord blood (UCB) is usually processed to total nucleated (TNC), but not mononuclear (MNC) fraction. TNC counts used determine UCB unit storage, release and correlation with time [1]. It has been mentioned in literature that there several factors affect harvesting of cells [2]. was set...

The purpose of this study was to evaluate human umbilical cord blood as an alternative to bone marrow in the provision of transplantable stem/progenitor cells for hematopoietic reconstitution. Although no direct quantitative assay for human hematopoietic repopulating cells is at present available, the granulocyte-macrophage progenitor cell (CFU-GM) assay has been used with success as a valid in...

A growing number of autoimmune diseases, allergies, and atopic conditions in recent years are calling for the development innovative therapies, such as those using stem cells with immunoregulatory activity. Because few often conflicting results scientific literature, it is still uncertain whether mesenchymal (MSC) could be a useful therapeutic strategy targeting B lymphocytes helpful treating a...

Human SCID repopulating cells (SRC) are defined based on their functional ability to repopulate the bone marrow of NOD/SCID mice with both myeloid and lymphoid cell populations. The frequency of SRC in umbilical cord blood cells is 1 in 9.3 x 10(5) mononuclear cells. We report that as few as 8 x 10(4) human cord blood mononuclear cells transplanted into NOD/SCID/B2m(null )mice resulted in multi...
