These days with novel facilities we have better understandings of sciences. There are many documented findings that might not be really correct. For example: origin of leukemic cells in Chronic Lymphocytic Leukemia. It is known that the origin of these leukemic cells is B cells. But these cells express CD5, a marker of T cells. Maybe these cells are really T cells or none of them. What do you think if we try to reconsider the old documented results in science?
