This data was developed using the undiluted version of this antibody ( ab15554 ). Insulin resistance changes over time during pregnancy, and in the last half of the pregnancy, insulin resistance increases considerably and can become severe, especially in women with gestational diabetes and type 2 diabetes. It is also believed to help regulate the mother’s metabolism by increasing maternal blood levels of nutrients for use by the fetus. The function of human placental lactogen is not completely understood, although it is thought to promote the growth of the mammary glands in preparation for lactation. The reproductive hormones act directly on the mammary gland, whereas the metabolic hormones act indirectly by altering endocrine response and nutrient flux to the mammary gland. 1986 Jun;108(6):251-5. After implantation, the inner cell mass (embryo) differentiates into an outer layer called ectoderm and an inner layer called endoderm.
