On the origin of B1 cells

A new MDC study may resolve a decades-old debate in immunology: A team led by Prof. Klaus Rajewsky reports in Science that distinct progenitor cells are not required for the development of B1 cells. Instead, the team’s experiments show that B1-typical B-cell receptor can reprogram B2 cells into B1 cells,…

Scientists generate functional, transplantable B cells from mice

Functional B-1 cells derived from mouse embryonic stem cells are capable of long-term engraftment and secrete natural antibodies after transplantation in mice, researchers report February 7th in the journal Stem Cell Reports. Scientists are interested in B-1 cells generated from pluripotent stem cells because they could be tested as a…
