Fong et al. employed whole genome microarray expression profiling to investigate the mechanism of response to peptidoglycan in neonatal neutrophils. Umbilical cord blood samples were collected after normal term vaginal deliveries, and isolated neutrophils were treated with 10 g/ml peptidoglycan or with medium only for 4 hours.
