Hamster Development
Introduction
These rodents belonging to the subfamily Cricetinae. Sexual maturity occurs at about 4 to 6 weeks and hamsters are seasonal breeders (April to October in the northern hemisphere) with several litters of 1 to 13 pups after a gestation period of between 16 to 23 days. The Chinese hamster (Cricetulus griseus) ovary (CHO) cells have been used widely in research as a host for protein production.
This animal model also demonstrates neural tube defects when exposed prenatally to hyperthermia.

Some Recent Findings
"Perfluorooctane sulfonate (PFOS) (C(8)F(17)SO(3)) and perfluorooctanoic acid (PFOA) (C(8)HF(15)O(2)) are synthetic chemicals widely used in industrial applications for their hydrophobic and oleophobic properties. They are persistent, bioaccumulative, and toxic to mammalian species. Their widespread distribution on earth and contamination of human serum raised concerns about long-term side effects. They are suspected to be carcinogenic through a nongenotoxic mode of action, a mechanism supported by recent findings that PFOS induced cell transformation but no genotoxicity in Syrian hamster embryo (SHE) cells. ...The whole results showed that PFOA acts as a tumor promoter and a nongenotoxic carcinogen. Cell transformation in initiated cells was observed at concentrations equivalent to the ones found in human serum of nonoccupationally and occupationally exposed populations. An involvement of PFOA in increased incidence of cancer recorded in occupationally exposed population cannot be ruled out."
