The added value of cultured cells in burn treatment: A systematic review.

Introduction: Advancements in resuscitative care and burn surgery have improved survival rates after extensive burn injuries, shifting focus to enhancing the quality of survival. Conventional treatment with split-thickness skin grafts (STSG) presents limitations such as donor-site morbidity, limited availability in extensive burn injuries, and hypertrophic scarring. Tissue engineering aims to address these drawbacks by developing optimal skin substitutes.

Small molecular weight alginate gel porogen for the 3D bioprinting of microvasculature.

In order to recreate the complexity of human organs, the field of tissue engineering and regenerative medicine has been focusing on methods to build organs from the bottom up by assembling distinct small functional units consisting of a biomaterial and cells. This bottom-up engineering requires bioinks that can be assembled by 3D bioprinting and that permit fast vascularization of the construct to ensure survival of embedded cells. To this end, a small molecular weight alginate (SMWA) gel porogen is presented herein.

Non-animal derived recombinant collagen-based biomaterials as a promising strategy towards adipose tissue engineering.

Adipose tissue engineering (ATE) has been gaining increasing interest over the past decades, offering promise for new and innovative breast reconstructive strategies. Animal-derived gelatin-methacryloyl (Gel-MA) has already been applied in a plethora of TE strategies. However, due to clinical concerns, related to the potential occurrence of immunoglobulin E-mediated immune responses and pathogen transmission, a shift towards defined, reproducible recombinant proteins has occurred.

An Update on the Survival of the First 50 Face Transplants Worldwide.

Importance: Since 2005, a total of 50 face transplants have been reported from 18 centers in 11 countries. The overall survival of the grafts has not yet been established.

Objective: To assess the survival of the face transplant grafts and evaluate factors potentially influencing it.

Reconstructing Curves: A Bottom-Up Approach toward Adipose Tissue Regeneration with Recombinant Biomaterials.

The potential of recombinant materials in the field of adipose tissue engineering (ATE) is investigated using a bottom-up tissue engineering (TE) approach. This study explores the synthesis of different photo-crosslinkable gelatin derivatives, including both natural and recombinant materials, with a particular emphasis on chain growth and step growth polymerization. Gelatin type B (Gel-B) and a recombinant collagen peptide (RCPhC1) are used as starting materials.
