Abstract Purpose: This study was designed to examine whether hyaluronicacid (HA) inhibits apoptosis in cumulus and muralgranulosa cells and to examine whether this effect of HAwas mediated through CD44. Methods: Mural and cumulus granulosa cells were obtainedfrom in vitro fertilization patients. The cells were culturedwith various concentrations of HA or HA plus variousconcentrations of anti-CD44 antibody without serum supplement.After 24 hr of culture, the cells were fixed and stainedwith Hoechst 33258. One thousand granulosa cells of eachconditions were observed by fluorescence microscopy. Results: HA inhibited apoptosis in both kinds of granulosacells, and anti-CD44 antibody prevented this effect of HA.Conclusions: The incidence of apoptotic granulosa cellswith fragmented condensed nuclei was reduced by HA viaCD44.
