[Proliferation and 3H proline incorporation of cells of palmar fibromatosis (Dupuytren disease)].

Proliferation and 3H-proline incorporation were studied autoradiographically in cells of Dupuytren's fibromatosis. It was observed that cells in the fibromatous tissue only exhibit a minimal proliferation rate. Increased 3H-thymidine labelling was found in vascular and perivascular cells. The finding may indicate that cells of perivascular areas contribute to the formation of the nodules. 3H-proline labelling was pronounced over cells of the fibromatous tissue leading to the assumption that these cells are highly metabolic.
