3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Implementing BMP‐7 Chemically Modified RNA for Bone Regeneration with 3D Printable Hyaluronic Acid‐Collagen Granular Gels

Advanced Healthcare Materials, EarlyView.
This study developed 3D‐printable THA‐Col microgels for delivering BMP‐7 cmRNA. The key result is that hMSCs transfected on the biomaterials showed BMP‐7 secretion levels comparable to pre‐transfected hMSCs, therefore introducing a cmRNA‐activated matrix to promote bone healing.

Increased nasal tip projection with “pseudo-flaps” using excess lateral cephalic alar cartilage [PDF]

Revista Brasileira de Cirurgia Plástica, 2019
Introduction: An increased nasal tip projection is sometimes necessary to achieve an appropriate proportion between nasal tip and dorsum. Numerous techniques and tactics have been described for this purpose using cartilaginous grafts obtained from the ...

Structured Light Projection Using Image Guide Fibers for In Situ Photo‐biofabrication

Advanced Materials, EarlyView.
Light‐based biofabrication is typically performed with single wavelength light sources and within benchtop devices. This work demonstrates FaSt‐Light (Fiber‐assisted Structured Light) as a new approach to achieve multiwavelength image projection using flexible image guide fibers, which enables a variety of applications for in situ biofabrication ...

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Repair of sheep articular cartilage defects with a rabbit costal perichondrial graft [PDF]

Acta Orthopaedica Scandinavica, 1991
A xenograft of costal rabbit perichondrium was transplanted to an articular cartilage defect in a sheep knee. After 12 weeks, cartilage was formed with increased calcification of the basal layer and a mean of 74 percent collagen type II. The synovium did not show any infiltration, indicating the absence of any immunologic reaction.

A Cadaveric Analysis of the Ideal Costal Cartilage Graft for Asian Rhinoplasty

Plastic and Reconstructive Surgery, 2004
Augmentation rhinoplasty of the Asian nose may be effectively accomplished with alloplastic materials. However, certain circumstances mandate the use of autologous grafts (e.g., dorsal augmentation that exceeds 8 mm and patient intolerance of alloplastic implants). Septal and auricular cartilages are inadequate for dorsal augmentation of the Asian nose.

Age-related difficulty in post-intubation tracheal stenosis reconstruction: a comparative analysis of CO2-laser, resection and anastomosis, and costal cartilage grafting techniques

The Egyptian Journal of Otolaryngology, 2022
Background Costal cartilage graft (CCG) sustains primary donor material for laryngotracheal reconstruction in patients with post-intubation tracheal stenosis (PITS). But, the elasticity and viability of CCG decrease elderly.

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.
