HA expression on murine BM HSCs.

(A) Sca-1 and Kit expression characteristics of Lin⁻murine BM cells; R1 sort region for HSCs. (B) HA expression on all R1 HSCs (gray line) as detected using HABP. (C) Control (Red 670 alone) for HA expression on Lin⁻Rh^dull cells. (D) HABP binding to Lin⁻Rh^dull cells. (E) HABP binding to Lin⁻Rh^dull cells following hyaluronidase pretreatment. The percentages represent the proportion of positive cells.
