What’s on the Differentiation poster
A definition and 6 facts worth remembering.
The process by which a less specialised cell becomes a specialised type, driven by differential gene expression rather than by any change in the DNA sequence.
- All somatic cells carry the same genome.
- Differentiation is regulated by transcription factors.
- Epigenetic marks — methylation, histone modification — lock in the state.
- Homeobox genes control body plan across animals.
- Differentiation is usually stable but can be reversed experimentally.
- Dolly the sheep demonstrated that a differentiated nucleus retains full potential.
- Cell types — ~200 in humans
- Same genome — yes
- Differs by — expression
- A neuron and a liver cell contain identical DNA and express entirely different subset…
Epigenetic marks are heritable through cell division, which is what keeps a liver cell producing liver cells.

- Who is the Differentiation poster for?
- Differentiation belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning cell biology can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Differentiation poster?
- Every cell has the same DNA. What differs is which genes are expressed. A wall chart earns its place by being glanceable from where the work is happening, so Differentiation belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Differentiation?
- Cell Cycle Control, The Cell Membrane and Cell Signalling sit alongside Differentiation in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Cell Cycle ControlThe Cell MembraneCell Signalling
- Is the Differentiation poster free to download and print?
- Yes. Differentiation downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Differentiation poster print at?
- Differentiation is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Differentiation loses nothing.Printing guide
