225:" since he was the first to purify blood forming stem cells in both mice and humans. His laboratory purified stem cells from other mature cells, such as B cells, by observing the different lineage markers expressed by each immune cell type. So when the immune cells of mice reacted with fluorescently labeled antibodies specific to effector cells, the mature cells were differentiated from the newly forming stem cells. His work has contributed to the understanding of how a single hematopoietic stem cell can give rise to specialized blood cells.
159:, rather than didactic lectures about scientific facts. He ran his first experiment there during his senior year in high school, to see whether he could repeat an experiment that had recently been published. He attributes his admission to college and medical school to the resulting publications, rather than to his less-than-perfect grades.

He developed methods to identify stem cells, and has extensively researched stem cells and progenitor cells. His research focus is "the phylogeny and developmental biology of the cells that make up the blood-forming and immune system." Weissman is widely recognized as the "father of

Weissman is also a leading expert in the field of cancer stem cell biology, where his work sheds light on the understanding of the pathogenesis of multiple human malignancies. He is also known for transgenic research in which human brain cells are grown in the brains of mice.
