Summary:

Bioprinting is an emerging technology with various applications in making functional tissue constructs to replace injured or diseased tissues. The interest in bioprinting of different biomaterials is rapidly growing, in which both hyaluronic and bioink have a unique role in this development. Hyaluronic acid is among the main components of the extracellual matrix and among the main biomaterials used in regenerative medicine due to its properties related to anti-inflammatory and angiogenetic activity. In recent years, thanks to the possibility of modifying its structural properties, it has also proved to be an excellent bio-ink for successful use in 3D cell printing. 

The aim of this special issue is to collect articles in which the authors have used hyaluronic acid as the main component of the bioink. Besides, novel bioink binding analysis with hyaluronic acid, the role of hyaluronic acid in bioprinting, and novel biomaterials are of interest.
