Cardiovascular 3D bioprinting

Bioprinting, 2022
Cardiovascular diseases such as myocardial infarction account for millions of worldwide deaths annually. Cardiovascular tissues constitute a highly organized and complex three-dimensional (3D) structure that makes them hard to fabricate in a biomimetic manner by conventional scaffold fabrication methods.

Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites

Advanced Functional Materials, EarlyView.
A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.

3D bioprinting skin

South African Journal of Plastic & Reconstructive Aesthetic Surgery & Burns, 2019
We used adipocyte-derived stem cells in combination with previously used methods (platelet-rich plasma and cell seeding) to create a 3D bioprint of skin on a hydrophobic matrix dressing. The patient was a 16-year-old girl with 65% total body surface area burns who had had multiple previous operations, and required additional skin with minimal donor ...
