Cultures of CD34⁺ derived HuMC over 6 wks in the presence of rhSCF alone, or with LPS, PGN or LTA. (A-D): Total cell numbers – left; HuMC numbers- right. A) 100 ng/ml rhSCF; B) 100 ng/ml rhSCF and 10–1000 ng/ml LPS; C) 100 ng/ml rhSCF and 10–1000 μg/ml PGN. Results are shown as the mean ± SEM of 3 separate experiments performed in duplicate; D) 100 ng/ml rhSCF and 0.1–10 μg/ml LTA. Results are shown as the mean ± SEM of 2 separate experiments performed in triplicate.
