Ratios of ic:sRHAMM and ic:sHA binding for mobilized BM HPCs correlate with those of paired mobilized blood HPCs collected at the same point in time. For each of 4 mobilized BL/BM pairs, the ratio of icRHAMM MFI:sRHAMM MFI or of icHA binding MFI:sHA binding MFI was analyzed by linear regression with sRHAMM or sHA binding as the dependent variable. (•) Ratios for RHAMM; (○) ratios for HA binding.
