- Key to cell type identity are evolutionary changes in the 'core regulatory complex' (CoRC) of transcription factors, that make emergent sister cell types distinct, enable their independent evolution and regulate cell type-specific traits termed apomeres.

The first rule is that “all living organisms are made of cells“, the second is that “the cell is the smallest structural and functional biological unit that constitutes a living organism”, and the third is that “every cell is derived from another cell” [2] (Figure 1).
The names of Schleiden and Schwann are almost as closely linked to the cell theory as are those of Watson and Crick with DNA. Like Watson and Crick, they had quite different backgrounds and met by chance in the laboratory of a distinguished scientist. Schleiden changed from law to botany in 1833 and joined the laboratory of Muëller in Berlin.

The cell theory. Hints at the idea that the cell is the basic component of living organisms emerged well before 1838–39, which was when the cell theory was officially formulated.

Oct 24, 2024 · Three critical discoveries made during the 1830s, when improved microscopes with suitable lenses, higher powers of magnification without aberration, and more satisfactory illumination became available, were decisive events in the early development of cell theory.
Aug 1, 2021 · This review explores the developments leading up to the establishment of the cell theory and cellular pathology and their subsequent refinements and applications while focusing on the individuals who have made seminal advances in the field.

Apr 21, 2024 · Explain the contributions of Semmelweis, Snow, Pasteur, Lister, and Koch to the development of germ theory. While some scientists were arguing over the theory of spontaneous generation, other scientists were making discoveries leading to a better understanding of what we now call the cell theory.
Mar 2, 2018 · Overton’s pioneering experiments (published between 1895 and 1900) showed cell volume changes in more than 500 different solutions and allowed him to conclude that a barrier distinct from the plant cell wall must exist and is made of ether-soluble components (i.e., is hydrophobic).
