In order to investigate molecular events involved in the regulation of lymphoid lineage commitment, we crossed lambda5 reporter transgenic mice to Rag1-GFP knock in mice. This allowed us to sub-fractionate common lymphoid progenitors (CLPs) and pre-pro-B (Fraction A) cells into lambda5(-)Rag1(low), lambda5(-)Rag1(high) and lambda5(+)Rag1(high) cells. Clonal in vitro differentiation analysis demonstrated that Rag1(low) cells gave rise to B/T and NK cells. Rag1(high) cells displayed reduced NK-cell potential with preserved capacity to generate B- and T-lineage cells, while the lambda5(+) cells were B-lineage restricted. Ebf1 and Pax5 expression was largely confined to the Rag1(high) populations. These cells also expressed a higher level of the surface protein LY6D, providing an additional tool for the analysis of early lymphoid development. These data suggest that the classical CLP compartment comprises a mixture of cells with relatively restricted lineage potentials, thus opening new possibilities to investigate early hematopoiesis.
