Development and Preliminary In Vivo Study of 3D‐Printed Bioactive Glass Scaffolds with Trabecular Architecture

Advanced Engineering Materials, EarlyView.
This study reports the fabrication of trabecular bioactive glass scaffolds (composition “1d”: 46.1SiO2‐28.7CaO‐8.8MgO‐6.2P2O5‐5.7CaF2‐4.5Na2O wt%) through vat photopolymerization and the relevant results from mechanical testing and in vivo implantation procedures in rabbit femora, showing great promise for bone tissue engineering applications.

PIK3CA mutations in vascular malformations [PDF]

Current Opinion in Hematology, 2019
Purpose of review Recently, it has been discovered that a subset of vascular malformations, of the lymphatic and venous type, are caused by oncogenic mutations in the PIK3CA gene. Now, efforts have been focused in the understanding of the molecular and cellular consequences of these mutations and the opportunities for novel ...

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

Combined surgical and medical treatment of a retroperitoneal lymphatic-venous malformation presenting with significant haemorrhage

Journal of Pediatric Surgery Case Reports, 2018
Lymphatic-venous malformations are rare congenital defects resulting from the abnormal communication between lymphatic vessels and systemic circulation, integrating the group of combined vascular malformations, with low-flow.

Glomangiomyoma of the knee : a rare juxtasynovial presentation [PDF]

, 2020
Glomus tumors are benign tumors typically located in the subcutis or deep dermis of the subungual region of the fingers. Histologically, glomus tumors are divided into three subtypes, in descending order of frequency: solid glomus tumor, glomangioma and ...

Vascular Malformations in Childhood

Actas Dermo-Sifiliográficas (English Edition), 2012
Vascular malformations are inborn errors of vascular embryogenesis present at birth that should be diagnosed in childhood and, when necessary, treated to prevent later complications. The current trend is to classify these lesions according to flow characteristics and the predominant type of vascular channel affected.

Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

The Route to Artery Mimetics: Hybrid Bioinks for Embedded Bioprinting of Multimaterial Cylindrical Models

Advanced Functional Materials, EarlyView.
The fabrication of a cellularized, multilayered 3D printed cylindrical model comprising hybrid bioinks inspired by the natural extracellular environment as an approach to artery mimetics, is presented. Using embedded bioprinting, interlayer crosslinking of self‐supporting concentric cylinders is achieved.
