Lactoferrin--a promising bone-growth promoting milk-derived glycoprotein.

Lactoferrin, an iron-chelating protein present in the granules of polymorphonuclear leukocytes and in the milk whey is having powerful osteogenic activity, as demonstrated by experiments performed in vitro on osteoblast cell cultures and in vivo on mice. It seems to be a promising factor to be applied in osteoporosis treatment.
