On the vegetalizing & neutralizing factors of Tiedemann in relation to the establishment of mesoderm in in amphibian development.
On the role of cell cycles in determination of tissue differentiation.
On his book of alpine flowers. On the application of his theory of cell-type expression to the cancer problem.
On his article 'Cell Type Expression mediated by Cell Cycle Events and signaled by Mitogens and Growth Inhibitors'. On the regulation of meso-endodermalization of amphibian ectoderm.
On his "working hypothesis that the control of cell type differentiation of a cell lineage during vertebrate ontogenesis can be divided into two: The immediate control is the direct control of genes to express the cell type. The remote control is exercised by a specific cell event which may or may not be influenced by the factors coming from the outside of the cell lineage. The completion of remote control activates the immediate control of a specific cell type within the cell lineage."
