Exploring the Cell, by Dr. Jessica Hayes

In ‘Exploring the Cell‘, the sixth in our weekly series of articles by NUI Galway researchers, Dr. Jessica Hayes, Research Fellow within the Orthobiologics group in the Regenerative Medicine Institute (REMEDI), takes us on a journey inside the cell and tells us how stem cells are being used in medicine to encourage the body to repair itself.

Cells – the building blocks of the human body. Here we demonstrate how molecules form cells. Groups of cells in turn form tissue which combines with different tissues to form an organ such as the heart, stomach, brain etc. Several organs that function together form an organ system i.e. cardiovascular, respiratory, reproductive systems etc. (Image source: http://www.studyblue.com/notes/note/n/introduction-to-the-human-body-chapter-1/deck/282266)

The Latin phrase ‘Omnis cellula e cellula’ or, all cells come from cells, was made popular by the German pathologist Dr Rudolph Virchow, and it is this concept that forms the basis of regenerative medicine. But what are cells and why are they so important?
