  • I'm used to thinking in terms of networks of genes: there are regulatory interactions between genes in a single cell that establish cell-type specific patterns of gene activity; all express a common core of genes, but different cell types, such as a neuron vs. a cell of the digestive epithelia, will also have their own unique special-purpose genes switched on.

  • Along this line of research, Marilyn Farquhar and I investigated the capillaries of the renal glomeruli and recognized that, in their case, the basement membrane is the filtration barrier for molecules of 100A diameter or larger; a byproduct of this work was the definition of junctional complexes in a variety of epithelia.
