Ricerche sull'aggregazione di cellule dissociate di embrioni di cavalletta (Schistocerca gregaria, Forskål). III. Studio istologico degli aggregati di cellule di embrioni a stadi diversi di sviluppo
The structures of aggregates obtained in vitro from cell suspensions of locust embryos were studied by light microscope on Epon-sections. The aggregates show an internal pattern which is the result of a sorting out and a specific association of embryonic cells. True aggregates are formed. A general characteristic is that no outer cellular boundary and no inner mesenchyme-like structure are present. The size and the structure of the aggregates differ according to the developmental stage of the embryos...
