【摘要】
In this study, different molecular weight (MW) carboxymethyl chitosans (CM-chitosan) nanoparticles were prepared by ionic gelification. The particle size of nanoparticles was around 180–250?nm by dynamic light scattering (DLS) and transmission electron microscope (TEM). With the increase of CM-chitosan nanoparticles concentration from 2 to 200?μg/mL, the growth inhibition effects on the keloid fibroblast increased. At the concentration of 100?μg/mL, CM-chitosan nanoparticles with MW 6.3?kDa had a significant inhibitory effect (inhibition ratio 48.79%) of the proliferation of keloid fibroblast. Compared with CM-chitosan solution, the inhibition of CM-chitosan nanoparticles were lower in prior period and similar in later period. By analyzing the different effects of chitosan, CM-chitosan solution and CM-chitosan nanoparticles on proliferation of keloid fibroblast, we have found that the carboxylmethyl groups of CM-chitosan play an important role in inhibition of proliferation of keloid fibroblast.
