Establishment of Proliferative Tetraploid Cells from Nontransformed Human Fibroblasts

¹Division of Morphological Science, Biomedical Research Center, Saitama Medical University, ²Department of Pathology, International Medical Center, Saitama Medical University

Although proliferative polyploid cells are necessary to analyze chromosomal instability of polyploid cells, creating such cells from nontransformed human cells is not easy. The present report describes relatively simple procedures to establish proliferative tetraploid cells free of a diploid population from normal human fibroblasts.

Here, we present a nonhuman primate model of mother-infant intervention for breastfeeding disorders in the presence of paternal inhibition and maternal neglect. The mate model video complements education to support primate and human caregivers with respect to infants with breastfeeding problems such as pain.
