Abstract

Colony stimulating factor-1 (CSF-1) concentrations in colostrum were 20 to 25 times higher than in serum at birth and declined with lactation. No difference in concentrations of circulating CSF-1, however, were noted between breast-fed and formula-fed infants, suggesting that milk-borne CSF-1 may feed back negatively on endogenous growth factor levels, may act locally in the gastrointestinal tract, or may be locally degraded.
