| 1 | ETP cells retained the ability to become either T cells or myeloid cells. | |
| 2 | This showed that ETPs give rise to myeloid cells in the normal thymus. | |
| 3 | This was accomplished by sorting the cells based on surface tags that are characteristic of the ETP cell type. | |
| 4 | The B cells migrate directly to organs without undergoing modification in the thymus and are responsible for humoral immunity (antibody production). | |
