Committed mast cell progenitors in mouse blood differ in maturity between T h1 and T h2 strains
Abstract Mast cell progenitors ( MC p) leave the bone marrow and migrate to peripheral tissues where they mature. Although the existence of committed MC p in adult mouse and human blood has been postulated, they have never been found. We have isolated a rare population of cells in adult mouse blood,...

Summary: | Abstract
Mast cell progenitors (
MC
p) leave the bone marrow and migrate to peripheral tissues where they mature. Although the existence of committed
MC
p in adult mouse and human blood has been postulated, they have never been found. We have isolated a rare population of cells in adult mouse blood, committed to the mast cell lineage. These were identified as lineage
