In general cell cultures even normal cells do not grow, accumulating as tissue as fffin vivofff. Hata et al. found that cultured cells formed three-dimensional tissue fffin vitrofff when APM was added to the culture. It was found in the study of type I collagen mRNA of skin fibroblasts incubated in APM containing cultures that APM not merely promotes the hydroxylation of proline, one of the collagen protein amino acids, but also activates gene expression of collagen itself.
In addition, AMP is also said to promote cell accumulation by proteoglycan sulfate, one of the combinations of proteins called proteoglycans, one of the extracellular matrix constituents other than collagen, and mucopolysaccharides. Information has been gradually accumulated that unveils diverse hidden actions of vitamin C.
