Studies in vitro of oncogenic agents have attained an ever increasing importance mainly because of the precision and ease by which events at the cellular and sub-cellular level can be followed. This article will examine the relevance of such data for the understanding of a much more complicated process — the development of spontaneous malignant tumors ...

Graft formation in plants involves the severing of the vascular system with consequent loss of water and solute transport throughout the plant. This transport must be restored to prevent death resulting from nutrient starvation or dessication.

The processes by which diversity is acquired and maintained during embryogenesis have been repeatedly described but are as yet not understood. One fascinating example of diversity following gastrulation is epidermal organogenesis and in particular embryonic tooth morphogenesis.

IN 1935, Gautheret1 published an account of in vitro grafts he had obtained between fragments of cambium of Populus nigra, Salix caprea and other trees, excised and cultured on artificial media. In attempting to repeat this work, I encountered some difficulties when tissues freshly removed from the plant were employed.
