stem cells are self-renewing and undifferentiated cell types that can be differentiate into functional cells. stem cells can be classified into two main types based on their source of origin: embryonic and adult stem cells. stem cells also classified based on the range of differentiation potentials into totipotent, pluripotent, multipotent, and unipotent. multipotent stem cells have the ability...

Mast cells are bone marrow derived hemopoietic (Kitamura, et al. [1-3]). The mast cell is one of the important in immune system. It from multipotent hematopoietic progenitor cells. produces a number cytokines to augment responses, growth, and differentiation other

Human mesenchymal stem cells (hMSCs), which also called mesenchymal stromal cells, are multipotent stem cell. Human MSCs typically are positive for the surface markers CD44, CD73, CD90, CD105, CD106, and also negative for hematopoietic markers CD34 and CD45.These cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...

stem cell therapy is a powerful technique for the treatment of a number of diseases. stem cells are derived from different tissue sources, the most important of which are the bone marrow (bm), umbilical cord (uc) blood and liver. human uc mesenchymal stem cells (huc-mscs) are multipotent, non-hematopoietic stem cells that have the ability to self-renew and differentiate into other cells and tis...

background  the mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. this source of stem cells avoids invasive procedures and the ethical controversy of embr...

Background: The hematopoietic system is sensitive to the adverse effects of ionizing radiation. Cellular therapies utilizing mesenchymal stem cells or vascular endothelial cells have been explored as potential countermeasures for radiation hematopoietic injuries. We investigated cells cultured from amnion                ...

Human adult hematopoietic stem cells are mostly quiescent or slow cycling. We have previously demonstrated that blocking of transforming growth factor-beta1 (TGF-beta1) is able to activate, in the presence of cytokines, primitive quiescent hematopoietic multipotent progenitors which could not grow in a two week semi-solid culture assay (short term culture). We have also shown that anti-TGF-beta...

Anthracycline antibiotics are potent anticancer drugs widely used in the treatment of solidtumors and hematological malignancies. Because of their extensive clinical use and their toxiceffect on normal cells, in the present study the effect of these drugs on multipotent hematopoieticbone marrow cells was investigated employing, viability tests, PARP cleavage, Hoechst 33258staining, DNA fragment...
