A new method for bone-marrow-derived liver stem cells isolation and proliferationApril 15, 2009Great interest has been aroused in the identification and isolation of liver stem cells from bone marrow cells. Several subsets of bone marrow cells have been found to have the potential to differentiate into hepatocytes, however, sorting based on immunological methods is difficult because of the complicated surface markers of the stem cells; furthermore, no report of successful passage has been published. A research article to be published on April 7, 2009 in the World Journal of Gastroenterology addresses this question. The research team led by Dr. Cai and his colleagues from the Affiliated Foshan Hospital and the Second Affiliated Hospital of Sun Yat-sen University established a carefully designed culture system to isolate, proliferate and differentiate liver stem cells directly from bone marrow cells, and they were able to achieve six passages of the stem cells. The results suggest that BDLSCs can be purified and passaged. The selecting culture system that contains cholestatic serum can purify BDLSCs directly from bone marrow cells, which provides an easy method to separate stem cells, by avoiding complicated immunological manipulation. The successful passage of the stem cells further verifies the proliferating ability of the cells, although the passage is limited, and further research will provide more experience. In this study, the authors used their original method to retrieve the cells, which are possibly BDLSCs. Then, they used fluorescence-activated cell sorting to determine the cells' characteristics before and after differentiation. This is an interesting and potentially important study, which suggests that bone-marrow-derived cells can be stimulated to expand and then differentiate into hepatocyte-like cells, which can possibly be used to treat liver disease.

Early heart attack therapy with bone marrow extract improves cardiac function A UCSF study for the treatment of heart failure after heart attack found that the extract derived from bone marrow cells is as effective as therapy using bone marrow stem cells for improving cardiac function, decreasing the formation of scar tissue and improving cardiac pumping capacity after heart attack. Bone marrow cell therapy may be beneficial for patients with ischemic heart disease The injection of bone marrow cells into the heart of patients with chronic myocardial ischemia (reduced blood flow to some areas of the heart) was associated with modest improvements in blood flow and function of the left ventricle.

CSHL team develops mouse models of leukemia that predict response to chemotherapy Being able to accurately predict how a given cancer will respond to chemotherapy would spare patients with non-responsive tumors the burden of undergoing toxic and ultimately unhelpful treatment. Just as important, knowing which of a patient's cancer-causing genetic lesions are contributing to drug resistance might help doctors redesign therapy for maximum benefit. Scientists uncover indicator that warns leukemia is progressing to more dangerous form Scientists at the Moores Cancer Center at the University of California, San Diego, Stanford University School of Medicine and other centers have identified a mechanism by which a chronic form of leukemia can progress into a deadlier stage of the disease.

Research shows cell's inactive state is critical for effectiveness of cancer treatment A new study sheds light on a little understood biological process called quiescence, which enables blood-forming stem cells to exist in a dormant or inactive state in which they are not growing or dividing. Bone marrow-derived stem cells may offer novel therapeutic option for skin disorder Stem cells derived from bone marrow may serve as a novel therapeutic option to treat a disease called epidermolysis bullosa (EB), a disorder characterized by extraordinarily fragile skin, according to a study prepublished online in Blood, the official journal of the American Society of Hematology. First Trial in the U.S. to Treat Both Ischemic & Non-Ischemic Heart Failure to be Performed by U of U Researchers Using Patient's Own Stem Cells Researchers at the University of Utah are enrolling people in a new clinical trial that uses a patient's own stem cells to treat ischemic and non-ischemic heart failure.
