Summary
Authors have investigated the ultrastructural morphology of transformation of homologous human tendon transplants. Tenoblasts and mast cells were found next to collagenous fibres originating in the transplant and disintegrating in the voluminous ground substance. The formation of new collagen tissue was of different grades; areas of only a few fibres and areas with oriented fibres were both present. Twenty months after inplantation parts characterised by apparently mature structure were found as well as abundant new fibre formation and mast cells.
Zusammenfassung
Es wurde das ultrastrukturelle Bild des Umbaus humaner homologer Sehnentransplantate untersucht. 120 Tage nach dem Einpflanzen des Sehnentransplantates fand man neben den aus dem Transplantat stammenden sich auflösenden kollagenen Fasern in der reichen Grundsubstanz Tenoblasten und Mastzellen. Die kollagene Neoformation war variabel, es kamen sowohl faserarme als auch geordnete kollagenfasrige Gebiete vor. 20 Monate nach der Sehnentransplantation waren neben den reif scheinenden Teilen auch ausgedehnte Faserneubildungen und in großer Zahl Tenoblasten zu finden.
