Guest editing an issue of ‘Essays in Biochemistry’ on the Extracellular Matrix

The extracellular matrix (ECM) has fascinated me ever since I was a student, newly introduced to the concept that interactions between cells build and sustain multi-cellular tissues. Unlike the cells of plants or fungi, animal cells have no cell wall: molecules secreted by animal cells into the extracellular space can bind directly to plasma membrane receptors to influence gene expression and cell behaviour.

Prime editing – a cutting edge new development in genomic engineering

Most biologists would agree that the most extraordinary development of the 21st century has been the discovery and manipulation of the CRISPR/Cas9 method of gene editing – a natural defence mechanism that bacteria use to defend against viral infection which scientists have hijacked to modify the DNA sequence of living cells.
