Research identifies earlier origin of neural crest cells

Neural crest cells—embryonic cells in vertebrates that travel throughout the body and generate many cell types—have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest ...

3-D printing, bioinks create implantable blood vessels

A biomimetic blood vessel was fabricated using a modified 3-D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein. The result ...

Biological material boosts solar cell performance

Next-generation solar cells that mimic photosynthesis with biological material may give new meaning to the term "green technology." Adding the protein bacteriorhodopsin (bR) to perovskite solar cells boosted the efficiency ...
