Abstract
Development of mature blood cell progenies from
hematopoietic stem cells involves the transition
through lineage-restricted progenitors. The first
branching point along this developmental process
is thought to separate the erythro-myeloid and
lymphoid lineage fate by yielding two intermediate
progenitors, the common myeloid and the common
lymphoid progenitors (CMPs and CLPs). Here,
we use single-cell lineage tracing to demonstrate
that so-called CMPs are highly heterogeneous
with respect to cellular output, with most individual
CMPs yielding either only erythrocytes or only
myeloid cells after transplantation. Furthermore,
based on the labeling of earlier progenitors, we
show that the divergence between the myeloid and
erythroid lineage develops within multipotent progenitors
(MPP). These data provide evidence for a
model of hematopoietic branching in which multiple
distinct lineage commitments occur in parallel within
the MPP pool.
