Figure 3. Secretion of KGF by Fp and Fr as a function of donor's age.
Evolution of secretion was estimated by linear regression in a cohort of 16 different pairs of Fp and Fr obtained from independent donors, ranging from 19 to 74 years old. Secretion of KGF was quantified. Values are expressed in pg/ml per 105 cells. (A) KGF secretion by Fp samples. (B) KGF secretion by Fr samples. (C) KGF secretion ratio [Fr/Fp].
