A total of 2.5 × 103 CD34+cells were added in duplicate to wells precoated with H120 or H0 fragments to which the standard mixture of growth factors at one fourth of the standard concentration in serum-free medium was added. Control wells were coated with BSA. Total cells were counted on different days of culture. The figure shows one of three similar experiments whose combined results are given in Table 2.
