From Lab to Life: How 3D Bioprinting Could Change Medicine Forever Scientists are developing 3D bioprinting technology to create tissues, blood vessels, skin, and experimental organ structures using living cells and biomaterials. 3D bioprinting is reshaping personalized medicine. It permanently solves the global organ shortage and prevents immune rejection. Surgeons use a patient's own stem cells…

Researchers at Tampere University have developed a 3D printed ceramic implant that closely replicates the composition and internal architecture of natural human bone. Published in Materials Today Bio, the work advances the case for patient-specific bone regeneration without the need for donor tissue, synthetic drugs, or growth factors, and may offer a more accessible path…

Wool-derived keratin membranes helped regenerate organized, stable bone tissue and may offer a promising alternative to collagen in regenerative medicine. A new study found that keratin, a structural protein taken from wool, can support bone regeneration in living animals. The material produced bone tissue that more closely matched healthy natural bone than collagen, which is [...]

This Collection highlights research on engineered allografts for regenerative medicine including engineered allografts, bioengineered grafts, decellularised scaffolds, tissue engineering, regenerative allografts, and composite tissue allotransplantation.

Researchers at Penn State have developed a new class of 3D-printed bioelectronics made of soft, stretchy materials, as well as an adhesive component that helps the device painlessly stick to biological tissue. The team reported that their new design, which they call CaroFlex and tested in a rodent model, relieved hypertension while causing much less damage to surrounding tissue.

Researchers at the University of Toronto's Institute of Biomedical Engineering have developed a new method to mature lab-grown heart cells, so they more closely resemble adult human heart tissue.

Scientists have developed a breakthrough injectable biomaterial that travels through the bloodstream to repair damaged tissue from within, reducing inflammation and jumpstarting healing. In animal studies, it successfully treated heart attack damage and even showed promise for conditions like traumatic brain injury and pulmonary hypertension. Unlike earlier approaches that required direct injecti…

Nature Communications, Published online: 28 April 2026; doi:10.1038/s41467-026-72468-8 Existing Janus hydrogels struggle to combine high-strength, asymmetric adhesion, and simple fabrication. Here, the authors develop a high-strength Janus hydrogel with bilateral asymmetric adhesion for wet tissue hemostasis and intestinal/intrauterine anti-adhesion.

By studying and engineering heart tissue in the unique low-gravity environment of space, the laboratory of Arun Sharma, PhD, is uncovering new ways to protect and repair the failing heart.

New study combines tissue engineering with synthetic biology tools to grow healthy liver tissue inside the body, and lays foundation for “smart” solid organ therapies

UNIVERSITY PARK, Pa. — Cell cultures — single layers of cells grown in a small dish — have enabled researchers to study biological growth, develop or test drugs and even discover what causes some diseases. Cell spheroids, 3D versions of cell cultures built using a process known as cell aggregation, are the next step in advancing this work, capable of more closely modeling real tissue. According t…

Scientists from Great Ormond Street Hospital and UCL have created the first lab-grown oesophagus and have implanted it in pigs, … read more

A new study shows that engineered, cell-free cartilage can safely support bone regeneration without provoking immune rejection. New research suggests it may be possible to repair major bone damage using a tissue implant that contains no living cells. By relying on the body’s own repair machinery, the approach aims to encourage new bone growth while [...]

At IMDEA Materials Institute, a new line of research is emerging with the potential to change how we treat injuries and degenerative diseases.
