VIP Guinea pig (Vasoactive intestinal peptide), a trophic and mitogenic factor, stimulates growth in whole cultured embryos. VIP Guinea pig functions as a simple gastrointestinal hormone and suggest a possible neurotransmitter function.

Vasoactive intestinal peptide (10(-7)M) shortened S phase and G1 phase of neuroepithelial cells by 50% (4.8-2.4 h) and 58% (1.9-0.8 h), respectively, compared with controls.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.
