We studied changes during lactation in the relative concentration of individual gangliosides in human milk from mothers delivering preterm and term infants. The relative content of GD3 was higher in colostrum than in mature milk, and tended to be higher in preterm colostrum than in term colostrum, whereas the relative content of GM3 was higher in mature milk than in colostrum, and was also higher in term than in preterm milk. As GD3 IS usually detected in developing tissues whereas GM3 IS more abundant in mature tissues, these results suggest a relationship between the presence of individual gangliosides in human milk and immaturity of the mammary gland in mothers of preterm infants.
