7 Stunning Cell Images from 2017
1. Human cell nuclei
A team of scientists from New York University used a state-of-the-art fluorescent microscope to observe human cell nuclei. They discovered that the nuclear envelope flickers over a period of a few seconds, and changes during the cell cycle.

2. Cell migration
Bumsoo Han, Professor of Mechanical and Biomedical Engineering at Purdue University revealed secrets of ‘en masse migration’ of fibroblasts, demonstrating how they cooperate to deform the matrix.

3. Pancreatic cells
Researchers from the University of Copenhagen have demonstrated how stem cells can be used to produce insulin-producing cells, paving the way for more effective treatments for diabetics.

4. Stomach gland regeneration
Professor Thomas Meyer and colleagues revealed a new mechanism of stomach gland regeneration and the effect that Helicobacter pylori infection can have on this process.

5. Lung cell development
Researchers from the Perelman School of Medicine have discovered new details of lung cell molecular pathways involved in repair and regeneration.

A team of researchers from UNC have discovered that nasospheroids, small balls formed from nasal cells, are filled with fluid that can help study how a patient will respond to CFTR drugs.

7. Immature vs mature stem cells
Researchers from the Karolinska Institutet have demonstrated a new way to distinguish between immature and mature stem cells, by identifying cell surface markers.
