In humans, current theories are that B-lymphocytes differentiate in the fetal liver and in the bone marrow of adults. Human T- and B-cells are mo

Perhaps the most attractive feature of embryonic stem cell lines is that they can be manipulated to differentiate into a diversity of cell types either directly in the tissue-culture dish or w
