Visual histological grading system for the evaluation of in vitro-generated neocartilage [PDF]

open access: yes, 2006
Here we present the development of a visual evaluation system for routine assessment of in vitro-engineered cartilaginous tissue. Neocartilage was produced by culturing human articular chondrocytes in pellet culture systems or in a scaffold-free ...

Designing the Next Generation of Biomaterials through Nanoengineering

open access: yesAdvanced Materials, EarlyView.
Nanoengineering enables precise control over biomaterial interactions with living systems by tuning surface energy, defects, porosity, and crystallinity. This review highlights how these nanoscale design parameters drive advances in regenerative medicine, drug delivery, bioprinting, biosensing, and bioimaging, while outlining key translational ...

Neural crest cell-derived VEGF promotes embryonic jaw extension [PDF]

open access: yes, 2015
Jaw morphogenesis depends on the growth of Meckel’s cartilage during embryogenesis. However, the cell types and signals that promote chondrocyte proliferation for Meckel’s cartilage growth are poorly defined.

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

open access: yesAdvanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Periodic Mechanical Stress Stimulates the FAK Mitogenic Signal in Rat Chondrocytes Through ERK1/2 Activity

open access: yesCellular Physiology and Biochemistry, 2013
Background/Aims: The biological effects of periodic mechanical stress on chondrocytes have been studied extensively over the past few years. However, the mechanisms underlying chondrocyte mechanosensing and signaling in response to periodic mechanical ...

3D‐Printed Unibody Microfluidic Devices for Organ‐on‐Chip Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A practical approach is demonstrated to 3D printing unibody microfluidic Organ‐on‐Chip (OoC) devices using commercial resins and desktop DLP printers. The demonstrated functional devices support 2D monolayers, 3D spheroids, and barrier tissues. With optimised design and post‐processing techniques, leak‐free, biocompatible microchannels and membranes ...

The oncofetal gene survivin is re-expressed in osteoarthritis and is required for chondrocyte proliferation in vitro

open access: yesBMC Musculoskeletal Disorders, 2011
Background Regulation of cell death and cell division are key processes during chondrogenesis and in cartilage homeostasis and pathology. The oncogene survivin is considered to be critical for the coordination of mitosis and maintenance of cell viability

The TGFβ type I receptor TGFβRI functions as an inhibitor of BMP signaling in cartilage. [PDF]

open access: yes, 2019
The type I TGFβ receptor TGFβRI (encoded by Tgfbr1) was ablated in cartilage. The resulting Tgfbr1 Col2 mice exhibited lethal chondrodysplasia. Similar defects were not seen in mice lacking the type II TGFβ receptor or SMADs 2 and 3, the intracellular ...

Liquiritin Exerts a Dual Effect on BMSCs Osteogenic Differentiation and Fracture Healing by Activating the ERK/JNK Pathway and Providing Antioxidant Protection

open access: yesAdvanced Therapeutics, EarlyView.
Liquiritin enhances the osteogenic differentiation of BMSCs and promotes fracture healing through the activation of the ERK/JNK signaling pathway and by exerting antioxidant protective effects. Abstract Liquiritin, a flavonoid from Glycyrrhiza uralensis L., has diverse pharmacological properties, but its impact on fracture healing is unexplored.
