Effect of the stability of the poly(gamma-glutamic acid)-ACP dispersion system on biomimetic mineralization of type I collagen

: In our system, the PGA-ACP solution stability and occurrence of intrafibrillar mineralization are directly correlated. Thus, we suspect that the same correspondence exists in other biomimetic mineralization systems and that a relatively stable supersaturated calcium phosphate solution may be a necessary condition for intrafibrillar mineralization.
