Expression of JAM-A in AGM, FL, and adult BM. Expression of JAM-A in whole tissues (left) and enriched stem cell fractions (right) in E11.5 AGM (A), E11.5 FL (B), E14.5 FL (C), E18.5 FL (D), and adult (8-12 weeks) BM (E). Representative data from more than 3 independent experiments are shown. Numbers on the graphs are percentages of JAM-A+ cells in whole tissue and on stem cell fractions.
