SABONET-MORENTE, L. et al. Regulation of bone modifications in the mother during pregnancy. Rev Osteoporos Metab Miner [online]. 2015, vol.7, n.1, pp.27-32. ISSN 2173-2345.  https://dx.doi.org/10.4321/S1889-836X2015000100007.

Pregnancy defines a model where the development of the fetal skeleton occurs in a short lapse of time. This achievement is accomplished under the control of the own fetus, who regulates the process through the signals generated in the so-called feto-placental unit. The maternal organism undergoes an adaptation process in which a drastic readjustment of mechanisms involved in the bone turnover takes place. Among the most obvious changes detected in maternal blood there are the increases in calcitriol, placental growth hormone, insulin-like growth factor -1 (IGF-1), estrogens and prolactin. There are also increases in osteoprotegerin and in the ligand of the receptor activator of nuclear factor kappa (RANKL). The phenomenon leads to transitory states of bone deterioration, which extends up to the end of lactation. The whole process is still insufficiently explored. We present an update of the changes affecting the mother and of those that arise in the placenta.
