The Cell Theory
... In 1839 the cell theory, as it came to be called, was first announced to the world by two scientists. Matthias Schleiden and Theodor Schwann concluded that all living things were composed of cells. This was the first statement of the cell theory. Twenty years later, Max Schultze pointed out that the ...

To determine DNMT3B function in human ES and EC cells, we have established inducible DNMT3B knockdown of human ES cells, and of both human pluripotent and nullipotent EC cells. We find that DNMT3B does not inhibit differentiation and apoptos ...
