Migration of cycling and noncycling LTC-ICs.
Transmigration toward MS-5 CM of cultured CD34+ cells was determined across BSA- or Fn-coated filters. Migrating and nonmigrating cells were replated in LTC-IC assays. The cycling fraction of LTC-ICs was measured by HU killing assays. Data represent percent migration of cycling and noncycling LTC-ICs (n = 4). *P < .05 compared with noncycling LTC-IC either across Fn or BSA.
