Die Wirkung der Ascorbinsäure auf die Faserbildung in Fibroblastkulturen

Abstract: Wie es in frfiheren Versuchen durch einen yon uns (Jeney) beobachtet wurde, zeigten die Hautwunden yon skorbutleidenden Meerschweinchen auch noch am 17. bis 23. Tage keine Heilungsneigung. Die mit Sehorfen bedeckte Wunde kann man nach dem Entfernen der Klammern leicht auseinanderziehen und den Wundrand vom Grunde leicht aufheben, so dab unter diesem eine Beutelbildung zum Vorschein kommt. Es bildet sich zwar Neugewebe, welches aber zum Zusammenhalten der Wundr/~nder nicht geeignet ist; in nach van Gieson gef~r… Show more

“…The Fe^ is believed to couple to the hydroxylase, thus activating it (Barnes 1969). The exact role of ascorbate, tetrahydropteridine, tetrahydrofolate, or dithiothreitol is not clear, but all stimulate proline hydroxylation (Peterkofsky and Udenfriend 1965, Hutton et al 1967, Priest and Bublitz 1967, Rhoads and Udenfriend 1970, Stassen et al 1973, with maximum activity at 75 to 100 pg ascorbate/ml medium (Swltzer and Sumner 1971) and Increased rate of collagen fiber production by fibroblasts (Jeney and Toro 1936). These agents may act by maintaining the Fe in the reduced state, since a,a'-dipyridyl, a Fe -chelator, inhibits hydroxylation even with saturating ascorbate (Blanck and Peterkofsky 1975).…”
