phenotypic modulation was also associated with an alteration in the relative proportions of type i and iii collagens synthesized , contractile smc synthesizing 78.1 +/- 3.6 % ( mean +/- s.d . ) type i collagen and 17.5 +/- 4.7 % type iii collagen , and synthetic cells synthesizing 90.3 +/- 2.0 % type i collagen and 5.8 % +/- 1.8 % type iii collagen .
