Most of the genes that were more abundantly expressed in deciduous dental pulp tissue have barely been discussed with respect to tooth and dental pulp tissues, although most of them have been found in association with the development of other organs or cancer, such as IGF2BP1. IGF2BP1 regulates the growth factor IGF2, and the results of knockout of the gene in mice suggest a role in organ development [29], while its expression is associated with ovarian cancer [30]. The gene discussed is IGF2; the disease is cancer.
