The results indicated that the fragments (HF3～HF8) with higher MW (≥3000) but not those (HF1, HF2) with lower MW (＜3000) had effects on CFU-MK growth. Moreover, HF3～HF8 could act synergically with TPO(10ng/ml) in promoting CFU-MK growth, but HF1, HF2couldnot. In addition, there were no differences in the effects ofHF3～HF8 on CFU-MK growth, suggesting that the synergy of heparin with TPO was associated with its MW, but not its sulfate content or activity of anticoagulation.

结果表明分子量较小的HF1和HF2(＜3000)没有促进CFU-MK生长作用，而分子两较大的HF3～HF8具有促进作用，并且前2者没有协同TPO(10ng/ml)的作用，后6者都有协同作用，后6者之间的作用比较没有差异，提示肝素协同TPO的作用与其分子量有关，而与硫酸基团含量和抗凝活性无关。
