Murine Sca-1+ cells activate platelets in a PSGL-1–dependent manner.
Expression of CD41 on the surfaces of murine Sca-1+ cells not incubated with platelets (A), incubated with platelets (B), and incubated with platelets in the presence of anti-CD162 blocking antibodies (C). Experiment was repeated twice with similar results.
